Title: TI-Nspire emulator
Post by: Goplat on February 25, 2011, 01:20:07 am
This topic is the new home for nspire_emu, the TI-Nspire emulator with the highly uncreative name.

Current version: v0.70 (post (http://ourl.ca/9360/330734), download (http://www.omnimaga.org/index.php?action=dlattach;topic=6763.0;attach=14364))

See below.

Perhaps. The CX isn't just a normal Nspire with a color screen. We know it has extra RAM and flash - what else in the hardware might have changed? We'll just have to wait and see.

Yay for that. Will there be another linux-compatible release? :)
Someone else made that, not me. I'm not familiar with Linux GUI libraries.

Anyway, here's the new version, 0.50:

I should probably update. I still run 0.20. X.x

Btw glad it's not available for download for more people and I'm glad this is still in the works. Are you still planning to post updates on UTI as well too? You could probably just link to the Omnimaga attachments since they aren't that big.

Will this version run at accurate speed?

nspire_emu works well on Wine, which lessens the urgency of having a native *nix version.

Great changes, as usual ;)

This is good to hear. Most programs work in Wine, but there are exceptions, such as Starcraft Battle.net and RPG Maker VX database editing section.

Excellent Goplat, as usual!
Does this mean that we now have enough information on the USB controller to implement on-calc drivers?
Title: Re: TI-Nspire emulator
Post by: Goplat on February 25, 2011, 12:04:31 pm

Timing is the same as it always was (1 instruction per cycle). I may make it more accurate at some point, but various features of the CPU make exact cycle timing impractical.

Does this mean that we now have enough information on the USB controller to implement on-calc drivers?
I think we already did: we know that it's Freescale's USB OTG module, revision 0x42; you can find documentation of it in the MCF54455 reference manual (the MCF54455 is not related to the TI-Nspire but just happens to use the same revision of this module). The host interface is based on EHCI 1.0 (http://www.intel.com/technology/usb/ehcispec.htm).

This is actually not new, there have always been problems when the OS tries to go into standby (after 3 minutes of idleness). In previous versions, you would see an infinite loop of unsupported USB port accesses:

And the calculator doesn't crash.

Yes. With the new modifications to the USB code, the symptoms have changed, but it's still the same bug. And I still don't see it any sooner than whatever the standby time is set to (unless emulation is sped up by pressing "`" or something)

On my computer, it typically runs around 100-200 million instructions per second. It depends heavily on the code being executed - plain arithmetic is fast, branches and memory accesses are slower, accesses to memory-mapped I/O ports are very slow. The main reason it's so fast otherwise is that I translate sequences of ARM instructions into the x86 code needed to emulate them, and execute that directly, so the overhead of figuring out what an instruction does is only incurred the first time it's executed. Without this feature, it's about 10x slower.

I have to ask: what hardware does the Prizm have whose emulation can be sped up with multi-threading?

Title: Re: TI-Nspire emulator
Post by: z80man on March 23, 2011, 04:51:40 am
I use multi-threading to control the hardware other than the cpu itself. So primary execution is handled by the first thread, hardware and peripherals on the second thread, gui on the third thread, and the plug-in app scripting language on the fourth thread.

The emulator works well with Wine :)

My scripts for launching the boot2, the 1.7.2741 CAS, and 1.7.2741 non-CAS respectively, are:
Code: [Select]
#!/bin/sh
pushd ~/TI-Nspire/ncubate_emu-v032b
wine nspire_emu.exe /B=boot2.img.raw /F=tinspire_boot2.bin /G=2000 &
popd
Code: [Select]
#!/bin/sh
pushd ~/TI-Nspire/ncubate_emu-v032b
wine nspire_emu.exe /C /B=boot2.img.raw /F=tinspirecas_1.7.2741.bin /G=2000 &
popd
Code: [Select]
#!/bin/sh
pushd ~/TI-Nspire/ncubate_emu-v032b
wine nspire_emu.exe /B=boot2.img.raw /F=tinspire_1.7.2741.bin /G=2000 &
popd

This requires creating the .bin files first, which is, IIRC, done with the /N option.

~/TI-Nspire/ncubate_emu-v032b is the folder where I store the emulator.

Have you notified that the OS 3.0.2 reboots infinitively ? (tested with boot2 1.4)

Post by: Goplat on July 09, 2011, 02:11:32 pm
Have you notified that the OS 3.0.2 reboots infinitively ? (tested with boot2 1.4)

I've noticed this. In OS 3.0.2, if you're using boot2 1.4, then it updates to boot2 3.0 and then immediately reboots (the reboot is to prevent the bricking that sometimes happened on-calc in OS 3.0.1). Of course, updating boot2 means nothing if you're using the /B option, so you'll get an infinite loop.

boot2 3.0 requires boot1 to work, and you could use the two of them together to start OS 3.0.2. (e.g. nspire_emu /1=boot1.bin /PB=boot2-3.0.img /PO=ti-nspire-3.0.2.tno) If you haven't made a boot1 dump, another way around this problem is just to use TNOC.

If you're trying to run OS 3.0.1, just use TNOC to get rid of boot2, and use a boot2 ripped from a lower OS version. (That's how Levak showed me.)

It looks like an Nspire CX emu wll have to use the boot2 that comes with the tcc/tco file, its different than the
one that comes with the tno/tnc files for boot2_3.1.131.
I get an error decompressing it , but it seems most if it is there. [I get an EOF error]
Title: Re: TI-Nspire emulator
Post by: critor on August 08, 2011, 04:58:11 am
The decoded CX Boot2 is correct.
It's just that the EOF code has been removed from that new CX Boot2.

But it then has to be decrypted, which means you need the CX Boot1.

Yeah, I probably should have given this thing a better name by now. I'm not too creative with names.
eNulator is nice, Nulator doesn't suggest the right pronounciation (without context, I would probably pronounce it null-a-tor or noo-later).

A while ago I came up with the name "TraNspire" - based on the way that I get decent emulation speed by translating ARM instructions into sequences of x86 instructions to emulate them.

I'm trying to install the emulator on my non-cas nspire but I have a doubt... I followed these <a href="http://hackspire.unsads.com/wiki/index.php/Emulators#Setup">instructions</a> and reached to the point of getting emulator screen to start the installation. Now, my doubt is: Should I have the calculator plugged in at this time and the OS will be installed automatically or should I let it load, then save the flash as <name>.tno and install it using the software from Ti-Texas?...  ???

I'm not sure I understand correctly your problem, but the emulator communicates neither with a real calculator, nor with TI's software (TI-Nspire Computer Link Software a.k.a "TINCLS", TI-Nspire Computer Software a.k.a "TINCS").

makes me think that you don't want to emulate a Nspire calculator on your computer (which you can do as described in the page you linked to, adding a /C switch to the final nspire_emu / ncubate invocation if you want to emulate a CAS calculator). Instead, I think that you want to try to use the CAS OS on your real, non-CAS Nspire calculator. Is that right ?

The nspire_emu / ncubate emulator doesn't communicate in any way with a real Nspire, and is not involved in making a real non-CAS calculator run the CAS OS.

All right!! Now I know why I couldn't install it!  :P

Indeed, the third-party PC emulator is just a PC emulator, and the official TI Nspire Computer Software does not even emulate the calculator, it's a similar code base recompiled for Windows and MacOS X :)

It became possible to hot-launch "other" OS during the spring of 2010, but "RunOS" was never released, for fear TI would lock down the calculators even further.
About one year later, and after TI added lots of lockdown, an independent reimplementation of RunOS was released as OSLauncher, which you can download from http://www.ticalc.org/archives/files/fileinfo/437/43701.html . OSLauncher itself did obviously not mention the dirty little secret that it could launch the CAS OS on the Nspire sold as non-CAS (but perfectly CAS-capable), but critor made a tutorial, which dramatically raised both usefulness and public awareness of OSLauncher. It can be downloaded from TI-Planet (http://tiplanet.org/forum/archives_voir.php?id=3517) , the required OS can be downloaded from TI-Planet again (http://tiplanet.org/forum/archives_list.php?id=OS%20Nspire), and you'll have to somehow find the "imgdump" tool :)

Several notes:
* OSLauncher requires Ndless 2.0, so it will work only on Clickpad & Touchpad calculators running OS 1.7.2741, 2.0.1.60 or 2.1.0.631;
* Ndless and OSLauncher must be launched again after every reboot;
* as is, OSLauncher cannot be used to cheat in standardized tests, unless said tests do not use the built-in Press To Test functionality (which triggers a reboot);
* due to changes in internal files across versions, it can launch only an OS of the same version as the host OS (1.7.2741, 2.0.1.60, 2.1.0.631);
* there will be some glitches, e.g. CAS functions not appearing in the functions catalog, odd display of the HOME screen on OS 1.7, etc.;
* and most of all, hot-launching the CAS OS on models sold as non-CAS can be extremely picky. It seems that it either works on the first or second try, or it might just happen to work, if you're lucky, after dozens of attempts...

OSLauncher just launches the other OS, it does not install it in any way; just reboot the calculator and the effect of OSLauncher is gone :)

The CX hardware is presumably reasonably similar to the Touchpad hardware (besides the difference in bpp for the screen), but there's a significant software difference: as mentioned by critor above, unlike the boot2 in Clickpad & Touchpad calculators, the boot2 in the CX is partially encrypted, and decrypted by the boot1.
This extra step is the cause of the noticeable delay (sigh) between 50% and 60% on the progress bar, a delay which doesn't exist on the older models...

In order to work correctly, an emulator for the CX would therefore require a boot1 image (*), unlike an emulator for the Clickpad & Touchpad... but the problem is, how to get that boot1 image ?
1) dumping the boot1 requires an arbitrary code execution exploit;
2) this hurdle will eventually be overcome in the future (like on pretty much any closed platform in the past two decades), but the result cannot be redistributed: the boot1 contains TI's copyrighted code...

Because of 2), users of a hypothetical CX emulator will have to go through the extra steps of dumping the boot1 of their own CX... but they cannot do that at the time of this writing, because there's no Ndless 3.0...


(*): embedding the boot2 decryption code into the emulator is not possible: circumventing protection measures would easily fall under the DMCA, and this time, TI would have a better case than they did for the signing key fiasco.

So I'm betting there could be a Nspire CX emu, but finding the boot1 images or roms will be a major PITA, leading to many forum posts asking where can we find them?

Yeah, we'll probably have to tell a significant number of people that they need to perform their own dumps, when they can.

Would it be more than a few calls to OpenSSL functions?

If it's similar to the other pieces of the encryption infrastructure, indeed, decrypting the boot2 wouldn't require more than several calls to OpenSSL functions. However, my understanding is that even distributing the decryption key(s ?) isn't perfectly legal in some countries (for questionable reasons, but it's the law) :(

But aren't the os update files (.tnc/.tno) also encrypted in a weird way? And the imgdump tool was distributed without legal problems?

They're ZIP files with a weird header; the boot2 (if any) is compressed with a non-standard format; the OS is encrypted with a symmetric cipher whose name evocates fish.

Well, the original author of imgdump removed all references to imgdump from his own posts, and all copies of imgdump able to decrypt the OS.

The version of imgdump that supports only the boot2 decompression cannot produce phoenix.raw files anymore, indeed.
The other method for decompressing a Clickpad/Touchpad OS, which involves running the Clickpad/Touchpad boot2 in an arm-none-eabi-gdb, keeps working.

OSLauncher just launches the other OS, it does not install it in any way; just reboot the calculator and the effect of OSLauncher is gone :)

So I tried do install the OSLauncher... But because I'm a NOOBBB... I updated the SO when I purchase the calc... That means right now I have the "deadly" SO 3.1 and I'm stuck!...

I tried to find a solution to do a downgrade with this SO and found a software called TNOC that claims that removes the boot2 from the SO and generates a new file without the boot2. Tried that and installed the SO generated by TNOC but didn't find any difference and couldn't do the downgrade..

Then I also read that there is a way to "crash" the SO by installing it and during the instalation, swap the keypad to the TI-84 and swap back again.. or something like that..
That should crash the SO and then should be able to install any SO.. Well, I don't have the TI-84 keypad to try this, but I notice that Texas in Portugal was offering these keypads to whom purchased an Nspire calc... But that promotion was only untill June! (how lucky am I?...  <_< )... I've sent the coupon anyways, together with a nice letter see if I can convice them to send me the keypad!....  ::)

In the meantime, do you have any other sugestions of how to "kill the beast" SO 3.1?...

Well, TNOC avoids installation of the newer boot2 (with more lockdown) on calculators that still have the old boot2, but is obviously powerless for calculators which already received said newest boot2 through unmodified OS upgrades :)

No, not at all: even if you erase the OS completely, the anti-downgrade protection enforced by the boot2 won't allow you to downgrade to any OS version supported by Ndless - and thus, to use OSLauncher.

I think its possible to downgrade the boot2 through the serial port (TTL), and then use downgradefix to remove 3.1.
But I'm not entirely sure.
Title: Re: TI-Nspire emulator
Post by: Lionel Debroux on November 18, 2011, 03:27:30 pm
If you manage to downgrade the boot2 to 1.4, indeed, you can use DowngradeFix, and the serial port lets this downgrade happen (critor did it on Levak's calculator shortly after the release of OS 3.0.1.1753)... but only a tiny minority of people have a USB TTL adapter, and I focused on solutions that don't require extra hardware.

I stand corrected, though - I should have mentioned the serial port :)

Here is the version capable of emulating the CX. Use the /M switch to specify the model of calculator to emulate:
/MC for CAS
/MX for CX
/MXC for CX CAS
/MM for CM
/MMC for CM CAS
For the CX/CM models, you can change the size of SDRAM to 64MB with the /R switch, and the size of NAND flash to 128MB with /N. (Both options are off by default just because they use a lot of memory and most programs won't need them)

I got rid of /N because it just adds an extra unnecessary step to the goal of creating a flash image with the OS installed. Here's a quick guide to getting set up without it.

TI-Nspire or TI-Nspire CAS, starting at boot2: (this will work with boot2 version 1.4 only; boot2 version 3.0 requires that you start at boot1. The newest OSes require boot2 version 3.0 unless you TNOC them.)
First run (non-CAS): nspire_emu /B=boot2.raw /PO=os.tno
First run (CAS): nspire_emu /B=boot2.raw /MC /PO=os.tnc
After installation is complete, go to "File -> Save As..." to save flash image
Subsequent runs: nspire_emu /B=boot2.raw /F=flashimage

TI-Nspire or TI-Nspire CAS, starting at boot1: (note that you must use the original boot2.img; don't decompress it)
First run (non-CAS): nspire_emu /1=boot1.raw /PB=boot2.img /PO=os.tno
First run (CAS): nspire_emu /1=boot1.raw /MC /PB=boot2.img /PO=os.tnc
After installation is complete, go to "File -> Save As..." to save flash image
Subsequent runs: nspire_emu /1=boot1.raw /F=flashimage

TI-Nspire CX or TI-Nspire CX CAS, starting at boot1: (this is the only way to run a CX OS - all versions of the CX boot2 require that you start at boot1. Again, you must use the original boot2.img; don't decompress it)
First run (non-CAS): nspire_emu /1=boot1cx.raw /MX /PB=boot2cx.img /PO=os.tco
First run (CAS): nspire_emu /1=boot1cx.raw /MXC /PB=boot2cx.img  /PO=os.tcc
After installation is complete, go to "File -> Save As..." to save flash image
Subsequent runs: nspire_emu /1=boot1cx.raw /F=flashimage

Please update the first page (which still gives version 0.53)

My advice for emulation is to download every single OS available, and keep it. (You never know when it might be useful.) I also have a shortcut to nspire_emu.exe for every single OS (each with different parameters), so I don't have to go into the console every single time I want to emulate the Nspire.

Your screenshots show that you're using MacOS X, where "gcc" is a quite old, and heavily patched, version of GCC, which will produce executables targetting MacOS X.
But what you want to do is to cross-compile, producing executables targetting Windows ;)
On Debian, installing a Win32/64 SDK takes only several clicks... but on MacOS X, unless someone provides ready-made DMG, it's probably going to be a major pain for you to install.

BTW, Goplat: when running "make" after replacing "gcc" with "$(CC)", where "CC = i686-w64-mingw32-gcc", and "windres" with "$(WINDRES)" where "WINDRES = i686-w64-mingw32-windres", i686-w64-mingw32-windres spits out:
Code: [Select]
i686-w64-mingw32-windres -v resource.rc -o resource.o
i686-w64-mingw32-windres: resource.rc:52: syntax error

Running it with -v provides the following additional clues:
Code: [Select]
Using `i686-w64-mingw32-gcc -E -xc -DRC_INVOKED  resource.rc'
Using popen to read preprocessor output

Running that command shows that DS_MODALFRAME and DS_CENTER are left unchanged by the preprocessor, so the SDK doesn't know about them. Ditto for IDOK and IDCANCEL at lines 57 and 58.

Those errors can be fixed by #include <windows.h> instead of just #include <winuser.h> :)

I do have a mingw32-crosscompiler installed, but I do not want to do cross-compiling. As only very few files in nspire_emu contain Windows-specific code I was thinking about trying to replace them. But I am not able to write Assember-code. I never learned it.
I can also use gcc 4.6.2 for compiling, but it makes no difference. No wonder, because gcc just calles "as". I'll try to update it as it is not installed with binutils but cctools on Mac OS X..-.- Ok, that's really stupid. I already updated my binutils to 2.21..-.-

EDITNOTE: I take some of what I said back.

As of nspire_emu_060, I think I need some explanation/help.
I decided to experiment more with this version since it is a major release, and start from scratch extracting boot2,files etc.
However when it came to creating a rom, it didn't work the same way it did in v053.
Some commands have changed since 053 and 060 (see screenshot)
Digging into Levak's batch file (from 2+ years ago, and I have edited for my own purposes), I found the /N command was used to create the rom image and it is different now as /N stands for Nand Flash (also was confused about what that meant until I read the v060 post today).
So as of v060, is there any way to create the rom using the command line nspire_emu.exe?

I could just run with boot 2 and install the OS and Save the flash within the emulator window, but since the /N does not mean create a new image anymore, is there any other way?
EDIT: I think /PB and /PO do the job, tho I'm not exactly sure what they do.

I may write a tutorial myself and put it in the Omnimaga Tutorials section for convenience.

Though, this is a great guide: http://hackspire.unsads.com/wiki/index.php/Emulators#Setup

Never mind I created a rom image using the way I said above, install OS and save Flash in the File-> menu. But it's a shame I can't create it directly commandline anymore. At least I think I can't

Post by: Jonius7 on February 25, 2012, 07:03:37 pm
To put it directly, as of nspire_emu_060, there is no way to create and save a flash image in the Windows directory directly from the command line (nspire_emu.exe) anymore? You have to press file, Save Flash as from the emulator window?

Never mind, I found it somewhere in this thread. Perhaps all of this could be put on the first post?

Question: I have some code programmed with the notes application on the Nspire CX. I sent it through TiLP to my computer. Then I opened it with nspire_emu. Is there any way I can get the code out? Copying and pasting like with student software doesn't work...

Thank you!
Title: Re: TI-Nspire emulator
Post by: Jim Bauwens on March 02, 2012, 05:57:43 pm
It's hard, but possible. It involves setting a breakpoint in nspire_emu and dumping the xml in a file.
You can find the exact details on Ndlessy (can't link now since I'm on my phone).

If you don't get it working, send me the file and I'll extract the code out of it tomorrow :)

Would it be possible to use this notepad program http://ourl.ca/8679 (http://ourl.ca/8679) to create a .txt, then somehow save or "send" the document back onto the computer in a compatible format (for editing with Notepad++ per se)?

I didn't find the breakpoint and xml thingy...

I'll PM you the document, good luck and Thank you!

Edit: I guess you can't PM attachments, so um, I guess I'll just post it.
Title: Re: TI-Nspire emulator
Post by: Jonius7 on March 02, 2012, 11:46:48 pm
that would be mighty useful, to extract what you had typed in a Notes app into a .txt file onto your computer. And vice versa.

Post by: Lionel Debroux on March 03, 2012, 01:37:16 am
Another way to get files off nspire_emu/Ncubate is to make a program that outputs the file to the RS232 port.
Title: Re: TI-Nspire emulator
Post by: bsl on March 03, 2012, 02:26:35 am
Another way is to open and load any file into a high memory location and use the debugger dump utility
The attached program does that, and breaks into the debugger for you.
You will have to concatenate the files made.

Ok, the code is attached.
Since I run an OS in nspire_emu that doesn't support ndless, I sadly can't use bsl's or Lionel's way.
What I do is copy the content I need to the clipboard (of the nspire) and then dump the memory of nspire_emu using gcore :P
Sounds strange, but works good for me :P
Then I just use a hex editor to find the offset of the data and use dd to get it :)

easier yet:

Then you dont have to look at the rest of the emulator code only what you are interested in.

Post by: cyanophycean314 on March 03, 2012, 10:20:54 pm
Thanks for the source, jimbauwens! I'm not using Ubuntu right now, so I don't think I can use gcore...

easier yet:
debug> w nspirememory.bin 10000000 2000000

Then you dont have to look at the rest of the emulator code only what you are interested in.
When I looked at nspirememory.bin through notepad, I got random symbols.

Another way to get files off nspire_emu/Ncubate is to make a program that outputs the file to the RS232 port.
I wouldn't know how to program something that would output through RS232. Not entirely sure what it is...  :P

Isn't there just a way to save a document outside of nspire_emu?
Title: Re: TI-Nspire emulator
Post by: cyanophycean314 on March 05, 2012, 05:40:49 pm
Sorry for the doublepost, but I just realized something really simple. You could just run Notepad, send the .txt file to your computer and then remove the .tns extension! I'm so stupid...  :banghead:  :banghead:

The only problem with that is notepad doesn't work on ndless 3.1...

You either have to use polydumper (available at tiplanet.org) on a real CX to get boot 1 in order to run nspire_emu, or ask someone else for a boot 1 raw file. However it technicially is considered illegal to distribute roms, it still happens sometime :P

I hope the Touchpad mapping is just wrongly configured for me, because it is quite confusing at the moment and nearly every key is mapped to another key that shouldn't be.

Hi everyone, (my very first message here)

As far as i can figure, 'touchpad' only works with non-cas OSes.
Unfortunately, for cas Oses, only 'clickpad' seems to work.
The problem is we don't get certain touchpad's keys mapped at all, eg: "trig>"+ "frac" + "?!>" + "pi>" + "ctrl+>="

Maybe Goplat (he's the man!) could find sometime to fix it, notably because nowadays most of the folks only have/want cas-machines.

Cheers,
SpiroH

Oh ... =(
I know that bug and I have no idea at the moment why it is crashing.
I've changed the code from using dynamic strings (like internally) instead of char * in utf16 in order to support larger string, but I somehow broke the cancel feature and them BOOM, I had school stuff to do (still now). I know where to look but do not have currently the tools nor the time to look and fix it.
Title: Re: TI-Nspire emulator
Post by: lkj on October 10, 2012, 09:54:53 am
I think the only problem was that if cancel or esc is pressed, it doesn't malloc, and therefore you free a not allocated pointer if you don't check whether it returns -1. At least this solved the bug for me.

You should also mention in the documentation that it doesn't work if lcd_ingray() is called, or change this.

I suppose you mean the Ndless SDK.
You can run it with the Ctrl+2 keyboard shortcut.

Or you can alternatively create your own .bat file to run it outside of the editor.
The executable file is nspire_emu\nspire_emu.exe and the parameters must be /1=path/to/boot1.img.tns /F=path/to/nand.img /MX (or /MXC for CX CAS).

OK, it appears that keeping these features in beta has caused some drama (just so people know: the only real reasons behind the lack of public release are fear that I might have accidentally broken something, combined with a big dose of procrastination), so here's a new release.

OK, it appears that keeping these features in beta has caused some drama

Yeah, I was surprised to read that strange idea here some weeks ago...


here's a new release.

  • implement CAS+ emulation (just enough to get the OS to boot, so I could test dumpers before sending them to critor... this wasn't really intended as a public feature, but someone on the mailing list wanted to see it and now that word has gotten out I can't really remove it now :p)
  • implemented sending files via XMODEM (mainly for CAS+ prototype OSes (1.0.3xx/4xx) - each one needs a different header so /PO= won't cut it - but works for any model)
/me feels concerned :P

Great! Thank you very much - at last! :)

Let's start the fun now ;)

Well I'm glad that holding up the release wasn't due to the other emulator. I feel it's best to release it for the rest of the community instead of delaying it just because of an issue with another program or user (unless of course the release wasn't complete and needed some time before coming out)

I might give this a try when I have some time, but I had so much troubles setting up nspire_emu in 2010 that it was finally Bwang who sent me a pre-set copy, so since then I have been using nspire_emu 0.20 >.< (and my real calcs). I'll need to find a few hours of free time to try to figure it out again with the latest build (which will take a while since I'm a bit busy helping Sorunome with Reuben Axe).

Will this build be posted on ticalc.org?

Pretty cool, nice to see this updated again.

Is there any chance of an update for the linux version? I don't remember who was adapting it in the past but there don't seem to be any that can support the CX :/
(I guess one could just use wine tho..)

Post by: Lionel Debroux on December 23, 2012, 04:13:32 am
nspire_emu has always worked pretty well under Wine, indeed :)
IIRC, the third-party Xspire version has been unmaintained since before the advent of the Nspire Touchpad.

I have a question for Goplat: how difficult would nspire_emu be to port, especially to Android? I might do that if the project is feasible.
Porting to another x86 OS like Linux or Mac OS X would require rewriting the GUI, and replacing some of the funky memory management code (I think I do have an unreleased Linux port of the memory code somewhere, but I never ported the GUI)

Since Android runs on ARM instead of x86, porting to Android would also require rewriting all the x86-specific code (asmcode.s, translate.c, and anywhere where I may have used inline assembly). I don't think the fact that it's an ARM CPU being emulated would help much, unfortunately.

You don't have to convert anything if you got the files with polydumper. Just rename the file extension from .img to .raw

It's probably: users\shagfried\documents\nspire_emu_070 (1)\nspire_emu.exe

also 1 more thing....... the actual emulator will not open every command I give it just keeps repeating the same thing with the menu that was first pulled up and yes I removed the .exe for the programs that followed or it says invalid argument
or is says boot2.raw is an invalid directory or it says boot2.img is an invalid directory
now it is just saying that PO=os.tno is an invalid argument
or that PO is an invalid argument
Title: Re: TI-Nspire emulator
Post by: lkj on February 20, 2013, 09:07:34 am
The following would be a valid combination of options if your OS is a .tno:
nspire_emu /1=boot1.img /M /PB=boot2.img /PO=310.tno

Replace the names after the equal signs with your own ones, obviously.

nspire_emu cannot run the Nspire port of Linux, as Linux uses the processor's features (especially the MMU) more extensively than TI's Nucleus-based OS does, and nspire_emu only implements what is needed for TI's OS to work.

In the menu I click connect after setting target folder to "My Documents" (without the quotes), then when I try sending a document, nothing happens at all ???. (Ndless 3.1 with OS 3.1 CX)

I think this is a bug with space characters in folder names, because sending to any folder with no space works fine.

It has worked alright for me. What are you doing exactly, and what error message (if any) do you get ? ;)

FWIW, nLaunch provides an alternate way to use Ndless on OS 3.1, but the installation procedure is more complicated, and it wouldn't necessarily solve your problem anyway.
Title: Re: TI-Nspire emulator
Post by: DJ Omnimaga on April 27, 2013, 02:51:06 am
Actually nevermind, it just appears to require several tries until it works. I clicked connect, set folder to ndless, sent file, it worked. I then sent a second file successfully (and almost instantly). However the file I sent froze when I ran it so I restarted the emulator, but then when I tried to set folder to ndless then connect it didn't work. I tried again in reverse order, to no avail, then after 1 minute I changed target folder name to My Documents and suddenly it said it sent the file to ndless folder. It wouldn't let me send the 2nd file (the calcemu_cx ROM) until about 5 more tries.

I get no error message. It just seems to randomly not work (although more often than working), so I have to retry sending up to 10 times until it is successful, while other times it works on 2nd try. I didn't have this problem in Nspire_emu 0.20 (I now use the one on BrandonW's server).

I use Windows 7 by the way.

EDIT: By the way, any reason why this emulator wouldn't run Jacobly's Z80 emulator? ???

Being under 1024, 1000 is a privileged port, so you cannot bind to it as easily as ports above 1024 (needs more privileges) :)
And yup, I use nspire_emu and its GDBstub exclusively under Wine under Linux, even if it's not very stable - crashes do occur, as you're experiencing.

Ah, so you actually want to debug a C / C++ program through GDB, not just use the GDBstub to benefit from an external GDB-interoperable debugger instead of the built-in debugger...
I've never done that, and from my work on forward-porting the GDBstub from Ncubate to nspire_emu, I'm not quite sure it's supposed to work (it requires extra support in the debugger, which wasn't updated for Ndless 3.1, IIRC).

Yes, it works now in r866 using the included nspire_emu.exe. :D

And this is unrelated, but in the nspire-gcc, nspire-g++, nspire-ld, and nspire-ld-bflt scripts, could you change $USERPROFILE in the last line (where gcc or g++ is called) to $home so Linux users can put static libraries in .ndless too?

This message is for Goplat and SpiroH, my humble contribution to these great emulators.

Testing nSpire_emu and kArmTI with some different ROMs I have found a problem emulating the CX prototype. Boot1CX-3.0.0.DEVBUILD rises a warning in the emulator and it breaks:
Code: [Select]
Boot Loader Stage 1 (3.00.DEVBUILD)
Build: 2010/9/14, 16:30:29
Copyright (c) 2006-2010 Texas Instruments Incorporated
Using developer keys

Last boot progress: 65
Warning at PC=00007718: Bad write_byte: 0001c634 00
debug> c

 I have to press c for continue the execution as a workaround.

Last night user fortytwo, in the IRC channel, helped on solving this issue. He changed line 47 of emu.c initializing the boolean break_on_warn flag as false in order to run smoothly. Maybe the emulator could include another command line argument such as /W in order to activate break_on_warn flag from the command line.

fortytwo compiled a test version and it runs smoothly.

The other issue I have is related to the Diags ROM. It can be executed using the following command line:

Code: [Select]
nspire_emu.exe /1=boot1cx.tns  /MX /PD=diagscx.tns
I can not go down and test other systems than memory. And when testing memory it reports a failure in the emulated flash. Is it a failure of the emulator or am I not configuring it correctly?

Thanks

I do extensively use GitHub and AFAIK there's no clone of this project there. I would like to clone the source code there so people can also send patches through there.

Thanks for all your work!

You can find the nspire_emu v0.60p1-gdb by Goplat repo clone here: http://goo.gl/E4uscN but I really do not know where is the latest code.

If you navigate a folder up you can also find the sources of other interesting tools like polydumper ( http://goo.gl/1QIgox ).

Legmet, AFAIK Goplat's nspire_emu source is accesible, while kArmTI is not.

As it was GPL and code was provided I tought a repo was being used.

If there's a repo I would like to mirror it and if not, this may be a good moment to create one.

Lets see what the author thinks :)

Post by: Legimet on December 11, 2013, 04:29:29 pm
Boot1, that's what I was saying, the repo is private, although the code for the latest stable version is released

antoniovazquezblanco: I don't think it's GPL. Actually, it has no license. I read once that no license makes it standard copyright, so nobody can redistribute or modify it. Goplat might want to change that.
Title: Re: TI-Nspire emulator
Post by: Boot1 on December 11, 2013, 05:28:12 pm
The copyright problem is then more complex since there are some forks of the original work done by Goplat like:
- ncubate (find the sources here http://www.ticalc.org/archives/files/fileinfo/433/43367.html ) based in Goplat's nspire_emu v0.32 (adds debug commands)
- kArmTI based in Goplat's nspire_emu v0.60 IIRC (adds skins)

It is sad not working together in different areas of the same emulator.

I'm sorry, I don't know why I thought it was GPL.

I think that the main reason why there's so much forking is because of the repo issue and maybe licensing issue although the last one is not a problem for me. I just want to collaborate.

Thanks Lionel Debroux for replaying. I'm sorry to say I could not answer because I'm not allowed to send PM.

For anyone interested, I have cloned the project in https://github.com/antoniovazquezblanco/nspire_emu (https://github.com/antoniovazquezblanco/nspire_emu).
I will be accepting changes! ;)

UPDATE:
I misunderstood that Lionel Debroux was one of the authors of this project. So although the mirror is up, I still waiting for the author to tell me if this is ok or not.

Thanks for your patience.

Antonio, The network already have mirrors of the 0.60 version of nspire_emu:
https://github.com/Nickorama21/Minecraft--TI-Nspire-CX-Port/tree/master/base/ndless%203.1%20sdk/nspire_emu
https://code.google.com/p/ndless/source/browse/Ndless-SDK/nspire_emu/

Nonetheless none of them are focused on the emulator. As I said before I would like your energy and interest in this project won't cause another fork but improve the current main source code another step forward keeping it as compact as possible.

In case that you want to contribute, the latest code I've found available is nspire_emu r96 inside ndless-​v3.​1-​beta-​r914-​sdk.​zip (http://www.unsads.com/projects/nsptools/downloader/download/category/1/file/83) that you can download from http://www.unsads.com/projects/nsptools/downloader/download/category/1




Regards and thanks to all people contributing to the community.

That one is very interesting to me. It would be perfect to be able to see the source code.

As it seems there's no public source code for that project.

I still waiting for a confirmation for finally leaving the repo where it is.
Please, let me know if that is ok.

Thanks.

The Ndless SDK integrates the latest public patches for nspire_emu I know of, that are Goplat's (the author of most of the code), Lionel Debroux's and mine, and is maintained with this goal in mind, it can be considered the most up-to-date. I'm not sure a GitHub repo is really what's missing, contributions are. But you may have a try with one.
Title: Re: TI-Nspire emulator
Post by: antoniovazquezblanco on December 16, 2013, 03:03:23 am
Thanks ExtendeD,

I've been looking around and I've found a Track page where I can't access the source code and a google project unoficial mirror. Where should I look for this?

Thanks in advance.

I'm not sure who created the google project mirror and if it's still active.

Is there any chance of moving nspire_emu to a new location for itself? It is quite dificult to mirror it this way :(. I believe it is a project on its own.

I've mirrored the project in Github https://github.com/antoniovazquezblanco/nspire_emu (https://github.com/antoniovazquezblanco/nspire_emu).

I've been trying to work on the sorce code for fixing warnings and for beeing able to compile it under both windows and linux.

After some work I realised that it no longer runs correctly under Windows and I don't know where I screwed up things so it would be very nice if any of you helped me find the mistake.

Here's a sample output:

nspire_emu's source moved to https://github.com/OlivierA/Ndless/tree/master/Ndless-SDK/nspire_emu, so consider forking the whole ndless repo for now.
Title: Re: TI-Nspire emulator
Post by: antoniovazquezblanco on June 10, 2014, 04:00:09 pm
Ouch! This is very frustrating... Although it wasn't a great job I spent quite some hours working on this... I find ndless repo very messy and I see different projets inside the same repo which in my opinion difficult to maintain...

If you accept sugestions git submodules and different repos will be easier to work with...

I don't know what I will be doing. I just feel I wasted a lot of time in this project for nothing. I will probably abandon it in its poor state because I see I'm too out of the development discussion...

Thanks
Title: Re: TI-Nspire emulator
Post by: Vogtinator on June 10, 2014, 04:05:30 pm
Just do a quick diff of the two source folders, there are no huge changes, really.
I totally agree with you, the ndless repo is indeed a big mess. I tried to clean up some parts on my fork (http://github.com/Vogtinator/ndless), but can't do anything as I can't really get nspire_emu to build under linux.. You might be able to fix this with your patches!
Title: Re: TI-Nspire emulator
Post by: antoniovazquezblanco on June 10, 2014, 04:11:53 pm
For being able to compile under linux you need to separate os dependent source files (gui and os) (done in my repo) and implement every function there for linux (not done). After that you should force 32bits compilation because of assembler (done) and you should add references for every symbol used both in c and asm to not include an underscore before them (done) so you will be able to compile in both platforms.

It is not very difficult to get done but it is sometimes tedious and ugly...

If I decide to continue on this I will probably try to clean up ndless repo first.

My patches are not difficult but they break the emulator in windows. If we are able to fix this issue it would be reasonable to merge my patches but not until then.
Do you feel in the mood for trying?

Thanks

Post by: Legimet on June 10, 2014, 04:15:08 pm
I agree that it's very messy. IMO the Ndless installer/resources, Ndless SDK, Ndless editor, Luna, and nspire_emu should all be in different repos. Vogtinator has done some things to clean it up though, you should check out his repo at https://github.com/Vogtinator/Ndless (https://github.com/Vogtinator/Ndless).
Title: Re: TI-Nspire emulator
Post by: Vogtinator on June 10, 2014, 04:16:56 pm
Getting the nspire_emu kernel to run on anything else than win32 is a PITA. Just so overly many calls to windows-specific functions for which there isn't a simple equivalent in linux. I tried it once to remove the GUI stuff and get it to compile, but it stopped at an undefined reference in assembler to a win32 call. That was too much for me at that time and now I think it's easier to just use mingw and wine on linux..
Title: Re: TI-Nspire emulator
Post by: antoniovazquezblanco on June 10, 2014, 04:27:39 pm
Congrats Vogtinator for your work. Your repo looks quite good.

I've implemented some of the missing functions although there's a lot of missing work there but I meant to fix the emulator in win32 with mingw. It compiles but I'm stuck because it doesn't emulate as it is expected. If that worked I could be able to send the patches either to the main repo or to your fork.

It looks good, but apart from the SDK part nothing works :)
Just try to execute the generated ndless installer or resources, instant crash..

I just created a nspire_emu repo and made an initial commit.
Also, with the latest mingw32-w64 version it seems to compile on linux, and boot1 executes successfully!
Title: Re: TI-Nspire emulator
Post by: Vogtinator on June 12, 2014, 07:20:36 pm
Bad news: With newer MinGW versions it compiles and runs sucessfully, but the 3.6 ndless_installer.tns segfaults the emulator.
Any ideas?
Title: Re: TI-Nspire emulator
Post by: antoniovazquezblanco on June 22, 2014, 03:37:17 pm
My version of the emulator works now on Windows. I fixed that anoying mistake I made. It compiles under linux with gcc but it is far from being usable as there are a lot of uninplemented functions.

I will have a look to your repo Vogtinator to see your changes but I want to make sure we will be all working toguether so I think we should talk about how things are going to be organised to avoid wasted hours.

Thanks for your time.

Compiles fine for me, but it's "nspire emulator v0.61", the latest is "nspire emulator v0.70[+Ndless-SDK patches]".
Also, why GTK for GUI? I'd use Qt for both platforms.
And could you include an option to do a windows build on linux, as it's impossible for me to test it?
Title: Re: TI-Nspire emulator
Post by: antoniovazquezblanco on June 23, 2014, 11:39:46 am
Yes it is v0.61 because I mirrored the old repo. As for the new repo I don't really know how to get a diff or a patch between 0.61 and 0.7 because I have changed a lot of files (although very little changes) and if I diff with the mirror version I don't know why it diffs the whole file. I have to look at it again (probably today).

I wanted to start with GTK because I use cinnamon and qt apps don't look that well... I also thought of leaving the windows gui as is for the windows platform...

About the windows build in linux I don't know how to do it... You will have to point me again in the right direction.

Thank you very much.
Title: Re: TI-Nspire emulator
Post by: Streetwalrus on June 23, 2014, 05:37:52 pm
Hmm qt apps can use the gtk theme. It just needs a couple seconds of googling and configuring but afterwards they look exactly the same.
Title: Re: TI-Nspire emulator
Post by: antoniovazquezblanco on June 24, 2014, 04:23:30 am
As it seems there's more people interested in a Qt gui I will think about it but a lot of work must be done before that.

When you talk about windows build in linux do you mean using mingw compiler in linux?

Thanks.
Title: Re: TI-Nspire emulator
Post by: antoniovazquezblanco on June 24, 2014, 05:52:27 am
Vogtinator, can you test the windows build trick?

Code: [Select]
cd src
OPTS=mingw make

I know this is not clean but I think it is better than the "prefix" solution there's in your makefile because prefix is tipically used for other things in a makefile.

Update: As I'm not able to get a clean diff (git and diff commands just diff the full code instead of the changed bits) of the changes between v0.61 and current version of the emulator, could anyone help me achieving this?

Update: It seems it is a file codification problem. Already working on it.

Thanks

You did it almost like I'd have done it, I'd just have a common section for not linux-native Makefile lines and a section for both MinGW and windows native builds.
And I'm getting a message, that "_WIN32_WINNT" would be redefined in gui-windows.c, so you may want to surround it with #ifndef.

Also you could help me finding the bug that prevents me from installing ndles 3.6 on a mingw compiled nspire_emu.
Could you add
Code: [Select]
printf("Data abort: address=%08x status=%02x pc=%08x\n", mva, status, arm.reg[15]);at the top of data_abort in emu.c and launch ndless_installer?
For me it outputs
Code: [Select]
Data abort: address=0101010d status=01 pc=102fd8e4 before "Segmentation fault".

Some things that I found:
-  This does not only happen in v0.7+Ndless patches, this also happens in previous versions (v0.61).
- It only happens if it was compiled with mingw under linux.
- I get no line with data abort information.
Title: Re: TI-Nspire emulator
Post by: Vogtinator on June 24, 2014, 11:43:28 am
Then it may just be my self-compiled ndless_installer which does something different then.
Could you try it on the not-mingw version with data abort printf()?

And I don't really know how to use GDB, but if I read it correctly the call to sched_process_pending_events() segfaults once before crashing the second time?
Title: Re: TI-Nspire emulator
Post by: antoniovazquezblanco on June 24, 2014, 12:15:06 pm
On linux:
- Your tns generates the same sigfault than the precompiled version.

On windows:
- Neither the original tns or your tns show that line of debug.
- Both install correctly.

And I don't really know how to use GDB, but if I read it correctly the call to sched_process_pending_events() segfaults once before crashing the second time?
It seems that it is true but the position of argv?? Argv is null?? I have to take a deeper look it must be in another point.
Title: Re: TI-Nspire emulator
Post by: Vogtinator on June 24, 2014, 01:08:48 pm
I found it: It's the call to longjmp that doesn't reach setjmp again.
But how can "restart_after_exception" get corrupted?

I found that some (older) MinGW versions have a bug that setjmp puts garbage into ebp, but the workaround -fno-omit-frame-pointer doesn't help so it's probably another bug.
Can you make a write breakpoint in gdb on restart_after_exception and longjmp in data_abort? The contents of restart_after_exceptions have to be the same as after the initial call to setjmp.

Edit: Set up a Win7 VM and compiled it. With gdb it outputs the same emu.c:551, argc = 65535, argv=something weird, and it indeed segfaults at main + 2088: call sched_process_pending_events(). As call pushes eip onto the stack ($esp), but $esp is somehow 0x10, it segfaults. That also explains why argc and argv are weird, they're stored on the stack.

Yup, I think the same. My changes are smaller: A message if ndless wasn't detected at gdb connection and prefixing emu output with "[nspire_emu]".

Maybe it got corrupted somehow. Can you step through setjmp or look when 0x10/16 gets written into restart_after_exception[1]?

Hmm. do __builtin_setjmp and __builtin_longjmp work? I tried it, it didn't make any difference, but I'd want to know whether they also call msvcrt.dll., probably 'cause I forgot copying nspire_emu.exe..
On http://sourceforge.net/p/mingw-w64/mailman/message/31232870 (http://sourceforge.net/p/mingw-w64/mailman/message/31232870) someone seems to have the same issue, even with MinGW 4.8.2, where the bug should have been fixed. It also happens only on 64-bit..
Could you try using the __builtins and -fno-omit-frame-pointer just in case and then look at the write to restart_after_exception (or not, if it works :D )?

Edit: You forgot
Code: [Select]
emuprintf("Ndless not detected or too old. Debugging of applications not available!\n"); :P

Edit2: Compiled, tested: WORKS!

Post by: antoniovazquezblanco on June 25, 2014, 02:42:43 pm
Compiled with __builtin_... + no -fno-omit-frame-pointer and it worked both in wine and windows 8.1  ;D

I will commit the mising line now.

We should report the issue...

For those who know the code of the project better than me, is apb.c code any useful? Can it be deleted? Old makefile didnt compile it and all the functions defined in there are duplicated. It is something someone is actually working on or it is something outdated?

I would also like to specify some kind of coding guidelines as sometimes things are very messy because of a non unified style. What do you think?

Thanks!

As for what first I think I have seen some code in your repo wich involved using Qt. I have very little idea about that so if you were able to start thinking about how things could be implemented it could help me a lot. On the other hand there are some ugly things around there and I feel like the code should be a bit more organized so I think I will be spending some time with that. apb.c code for example, I don't know if it is usefull for anyone, data types are a mess, I would like to parse arguments from command line with optarg for simplicity (maybe a gui if no argument is provided...), etc.

I've been filling some of this things in my repo issues list in order not to forguet them.
https://github.com/antoniovazquezblanco/nspire_emu/issues?state=open
Pick one if you feel in the mood :).

Some "core" code has ben initially ported to linux (see os/os-linux.c) but a lot is missing.

Wine was complaining about a missing libmpg123 lib. Installed it and now I can't use the emulator at all...

It seems to boot but at some point loading the os the window doesn't redraw anymore...

Anyone experiences anything similar?

PD: I've also updated my packages (Archlinux)...
Title: Re: TI-Nspire emulator

I use Arch too. Wine wants libmpg123 for some reason and this is not program specific.

This has been quiet for a long time. The repo has also been moving slowly but after some commits I think the code is a bit more clean.

The emulator now uses a different method for parsing command line arguments. There was functionality that was not listed in command line options and now is. Parameters have changed a bit and testing is needed. It would be nice if any of you could test the devel branch of the emulator and report bugs if found.

The code is in https://github.com/antoniovazquezblanco/nspire_emu (https://github.com/antoniovazquezblanco/nspire_emu).

Thanks!

I would like to have more time for it but from time to time I try to clean some code and improve some bits.
Some bugs were fixed and code is cleaner in my opinion. Argument parsing is better now but no new functionality yet. I hope this encourages people to start coding a bit :)

In theory you could run X and wine with qemu and binfmt support in a chroot.
If you just want some calculating capabilities similiar to the nspire, there are some apps in the store.

Yes, in the way of "implementing support until it's usable", but not in the way of "I'll maintain it until we both are dead" :P
There is no current "maintainer", it's just floating around the internet.

Can someone install Qt for Android and try to cross-compile the code from http://github.com/Vogtinator/nspire_emu?
It should be possible now to run it on other platforms. It's probably a bit too slow to be usable, but it should work.

Edit: With some minimal changes it compiles and runs, but crashes somewhere in boot1. I'll debug it and upload for tests, if anybody wants to test nspire_emu on his android phone.

You might want to try try radare2. You can import the Nspire .idc files using a script called idc2rdb. Although radare2 doesn't have a good GUI and it lacks decompilation support.

In theory you could run X and wine with qemu and binfmt support in a chroot.
If you just want some calculating capabilities similiar to the nspire, there are some apps in the store.
I tried that once, but apparently qemu required a patch for something called "NTPL support" to run wine :P

The core of a good reverse engineer tool is to provide a nice user interface. Decompilation is mostly useless anyway. I'll try it, do you use it?

It may work but be even slower as iOS has some massive restrictions. But I guess it would run on iOS as well if it works on android.

Does ARM support hardware virtualization ?
Most ARM processors in consumer devices don't, but AFAIK Aarch64 requires it. (Xen and KVM support the extensions already, they're quite new)
Some kind of accelleration would be needed, though, I had to wait for ~8m to boot this:
(http://img.ourl.ca/nspire_android.png)

Also, I had to do a quick hack to display the 4bit framebuffer, that's why it's blue for now.
I had to use a classic image as my device doesn't have enough RAM to allocate the various caches, flash and SDRAM, I'll have to change that to utilize nmap.

Yeah, I can upload the "working" app if you want to, but it'll take some minutes to fix some stupid issues (using "-Os" instead of "-Ofast" e.g.) and the framebuffer.
Also, as I have hardcoded the path to boot1 and flash, is "/sdcard" ok?

For me, it's either /sdcard0 or /sdcard1, depending on if I use the flash or the SD card.

For me, the path is /sdcard so it should definitely work ^^ I'd rather see it customizable tho so I can throw stuff on my SD card as my flash is only 1GB <_< but that's something for later.

The flash image that can be booted using the provided boot1. I called the file "flash_3.9_nothing.img" as I had "flash_3.9_cas.img" etc.
It doesn't matter whether it's 132MiB or 32MiB.

Edit: boot1 not boot2.

Which version on which platform are you using? It should work just fine on linux, windows and android. Mac crashes due to some mmap weirdness. (https://github.com/Vogtinator/nspire_emu/issues/3)

Oh, ok. I just read the last posts again and I don't know how I assumed you weren't running the android version  :banghead:
You need at least 1GB RAM and you definitely need to use a 32 MiB flash image if it crashes due to mem exhaustion.

If you can "adb logcat" your device, it should print some OOM kills and then a final SIGKILL to nspire_emu.
Title: Re: TI-Nspire emulator
Post by: lkj on November 12, 2014, 04:47:14 pm
It actually starts, but prints "Warning (00003c18): Bad write_word: 5480040c 00000000" in the debug tab. I'm being very imprecise today :banghead:
It expects a classic boot1 and a classic non-cas rom created with nspire_emu 096 on the PC, right?
Title: Re: TI-Nspire emulator
Post by: Vogtinator on November 12, 2014, 04:50:27 pm
As long as the flash is for the right model, it should automatically set the correct model number and id.
You can also try to run boot1 cx. I have never seen that error before, is it always the same?
Title: Re: TI-Nspire emulator
Post by: lkj on November 12, 2014, 05:06:46 pm
No, the error changes almost every time. It's always "Warning (00003c18): Bad write_word: [...] 00000000" but the [...] could be any of these (and more):
5480040c
6200040c
9940040c
5640040c
53c0040c
9700040c

It doesn't crash with the CX boot1. I don't know if it's loading very slowly or if it's hanging or what because I can't enter the debugger there.
Title: Re: TI-Nspire emulator
Post by: Vogtinator on November 13, 2014, 12:28:13 pm
If you enter the debugger, nothing will happen until you execute a command, like "s" or "r".
I have seriously no idea where the error comes from, are you sure you have the correct flash image?
I just flashed 4.2.2 to my tablet and it works without (major) issues there.

What I really don't like to see is that the write address changes everytime.
Title: Re: TI-Nspire emulator
Post by: lkj on November 13, 2014, 01:06:54 pm
I know, I tried to execute "r" and other commands but nothing happened. I'll try again with other CX flash images. It's strange that it seems to freeze with the CX boot1 while it just runs into an error with the classic boot1.
I'm pretty sure the flash images are correct (unless I should create them with another version of the emu on the pc side. I'm using the one from the latest prebuilt ndless sdk).
I have android 4.4.2 on my phone. It has a normal armv7 processor and much more RAM than needed.
Title: Re: TI-Nspire emulator
Post by: Vogtinator on November 13, 2014, 03:16:07 pm
I believe I found the issue:
In nspire_emu theres an array called addr_cache, which holds two values (read and write) for each 400 bytes of memory.
Each entry (For example, if you want to read at 18000020, its entry is addr_cache[(0x18000020 >> 10) << 1]) contains the following information:
-Pointer: If you add the address you want to access to the entry, bit 31 is clear and you can dereference the result directly
-Special entry: If you add the address you want to access to the entry, bit 31 is set
-MMIO: A special entry which (the entry itself, not the result of the addition) has bit 22 set
-Invalid entry: A special entry which has bit 22 clear.

The issue is, if the allocated memory is beyond 0x7CFFFFFF, you lose information and it crashes.
I expanded the entry format to 64 bits (but kept the bit positions!) and it works, except for rare occasions when the address itself has bit 31 already set!
So now I have to either:
-Fix the algorithm for computations
-Make a new format

This issue is also present on 32bit machines, but nspire_emu invoked VirtualAlloc with some parameter magic so it's always below 2GiB.
This "trick" also works on linux,  but not on mac.

I went for the latter, but it's slower, for now. I encode the 3 various kinds of entries in the lowest 2 bits.
Do you have a better suggestion?

I recompiled the App (https://dl.dropboxusercontent.com/u/105478372/QtApp-debug.apk) and it may work now, although I don't consider this as fixed.
I also solved the bug that you can't exit if the emulation thread enters an infinite loop (that's what happens if addr_cache overflows, what probably happened in your case).
Title: Re: TI-Nspire emulator
Post by: lkj on November 13, 2014, 04:19:30 pm
I can't think of a better solution that works in all cases...
Sounds like that was probably the problem with both errors for me, yes.
The directory is /sdcard/ on my phone instead of the /sdcard1/ in the current build, so I couldn't test if it's fixed.

Great! It really fixed everything, I could load a CX and a classic OS without any problems. Booting took about 2-3 minutes :)
The only thing that doesn't seem to work is the "Reset" menu entry, but that's a minor problem (actually not important at all as long as there's no input :P).
Oh, and the progress percentages are displayed after each other on a very long line instead of overwriting the old percentage as on the PC.

No, don't delete your repo, instead push upstream whenever you like to. If it's in any way a massive change, a pull request is the best way to avoid merge conflicts.
Branches on upstream work as well, but there are no pull requests for them. At least that's how it works now for ndless-nspire/Ndless and Vogtinator/Ndless.

Let's forget about that (and your doublepost). When I read your message I just laughed really badly xD
It's not really bad to delete an upstream repository as someone will have a working copy with git history and thus every branch can be restored.
But still, it's not a bad idea to check everything twice before deleting...

Anyway, back to the code. How should the keymap be implemented? I thought about a direct mapping of characters, so to type a ( you just have to type (. For {, { and so on.
The downside to this is that the shift key can't be controlled anymore. What do you think about that?

Yeah, I think it would be a good idea. But we obviously still need buttons, too (for nspire-specific keys...)
When the core stuff are done, a skin-based thing (well, at least, a keyboard that looks like the real one) would be good too, like what KarmTI does (or to a lesser extent, nRemote (https://github.com/adriweb/nRemote#i---about-)).
I looked at Qt and frame/headless windows (such that custom window shape/frames could be done for the skin-based interface, if that's the plan) and it looked relatively easy (3-4 lines of code in mainwindow actually, for making the window "custom", with transparent background etc.). I think I have the details bookmarked somewhere...

The downside to this is that the shift key can't be controlled anymore. What do you think about that?
Hmm. Is there any specific application of this where it could be an annoyance ?
But once again, the mapping could be temp. disabled with an option, too... :P

I looked at Qt and frame/headless windows (such that custom window shape/frames could be done for the skin-based interface, if that's the plan) and it looked relatively easy (3-4 lines of code in mainwindow actually, for making the window "custom", with transparent background etc.). I think I have the details bookmarked somewhere...
Hm, what about Qml/Qt Quick? It seems to be perfect for this, it supports SVG natively and makes design relatively easy.

The downside to this is that the shift key can't be controlled anymore. What do you think about that?
Hmm. Is there any specific application of this where it could be an annoyance ?
But once again, the mapping could be temp. disabled with an option, too... :P
Yeah, only double the work...

Ah, maybe. Cool then. I have never used it, so I didn't think about it.
As long as it still works on all platform without adding much size overhead (?)

Two seperate modules actually, one of them is WebKit's JavaScriptCore IIRC...

I've been touching the keymap because I wasn't able to use the calculator at all. I could add the remaining keys to the map if you want me to. What do you suggest for the special keys? F1-F12? Alt? Ctrl? ...

It would be very nice to detect mouse over the Lcd widget and send it to the emulator...

That's the problem. What about "easy", "normal" keys like (?
You can't assign it to "(" on the keyboard as it's Shift-8. (or Shift-9 for qwerty) and that means shift is active.
Maybe distinguish between left and right shift?

That's working already (LMB: touch, RMB: click), if you try pyWrite or crafti. Only the OS doesn't like it.

Qt::Key_Question among others is working for me...  :)
I cannot get the widget to capture Key_Tab... Selection is moved to the next widget. I know very little about Qt.

Of course, shift isn't implemented yet.

Right click the right edge in the center and the cursor moves.

An idea for the shift implementation based on the behavior of the calculator:
- Situation 1: Shift is pressed, another key is pressed and released, shift is released. Normal keyboard operation (produces symbols such as ? or {).
- Situation 2: Shift is pressed and released (activates calculator shift), and another key is pressed and released...

If the key release event is available shouldn't be to difficult to implement although it is not very intuitive...

That could work, what do you mean by normal keyboard emulation?

"Operation"... May be Spanglish. I meant the computer OS handles the keypress.
Title: Re: TI-Nspire emulator
Post by: Vogtinator on November 22, 2014, 06:48:07 pm
Oops, of course, operation not emulation.
So if the { key is pressed, it triggers Ctrl and then the ( key on the calc?

That would be very nice... I think it would be a good idea to have a look on how the official emulator handles all this details.
Title: Re: TI-Nspire emulator
Post by: Vogtinator on November 22, 2014, 06:53:39 pm
It doesn't emulate at all. It's a port of the calc's engine to the pc. That's why for instance ndless_installer_3.6 crashes the PC software as well.
Title: Re: TI-Nspire emulator
Post by: Adriweb on November 22, 2014, 07:13:04 pm
There's also the far-fetched way to directly send the navnet keyevent corresponding to the key... but.. yeah :D

edit : oh wait, that'd mean OS mainly, though ^^

Can download boot2 and OSes from TI-Planet, but boot1 you'll have to dump them yourself though :P
Title: Re: TI-Nspire emulator
Post by: Vogtinator on December 13, 2014, 02:04:19 pm
Oh, I saw boot1 for the classic calcs so I assumed there are also boot1's for newer models. There is a "Boot1 TI-Nspire CX prototype (v. 3.0.0.DEVBUILD)" though, that may work or did the keys change?
Title: Re: TI-Nspire emulator
Post by: Adriweb on December 14, 2014, 04:46:08 pm
I keep forgetting why the CX prototype one is there but I believe it won't work with newer stuff, so...
The old one for clickpad ( https://tiplanet.org/forum/archives_voir.php?id=13343 ) is for "debricking" some prototypes, I'm not even sure if it's useful anywhere else anyway.

Anyway, to dump your boot1, @jamesguessis, you can use PolyDumper (https://tiplanet.org/forum/archives_voir.php?id=3829).

I kinda lost my nspire, this is the only reason i'm trying to USE the emulator.

EDIT:so I've dumped my ROM, I was told I have to unpack it or whatever,  how do I do this??

Hey Vogtinator and antoniovazquezblanco (and anybody I should have addressed),

Just wanted to say I was able to compile and run the emulator you are working on from source! :)

I am on Linux (OpenSuse), I got a TI-NSpire CX with 3.6.0.550 image running and installed NDless 3.6 on it :)

Thanks for working on this!  And have an amazing day!

Great! I assume you used a flash file createy by nspire_emu v0.70?

If you're running on 64bit, could you try the latest source with x86-64 JIT?

Correct.  I don't know (and still don't) if it can create flash file.  But I figured I'd try with a nspire_emu v0.70 created flash file.

It did take me a couple of minutes to figure out how to use the program.  For instance to install Ndless 3.6 you need to press the 'menu' key; and I had to look at the source to see Alt + M (and to turn on the calculator after it went into sleep: Alt + Shift + Esc).  Also transferring a file is simple (drag-n-drop) though it did take me a minute to try that.  But got that all figured out! :)

If you're running on 64bit, could you try the latest source with x86-64 JIT?

Sure thing!  I got the latest and used QtCreator.  Below is a screenshot of it running as well as a screenshot of the QtCreator settings I had.  Thanks again!

That's awesome if you added a JIT! I'll try it soon.
