Sadly, I think I have an issue with the touchpad here. :(

The touchpad itself has stopped working now for me. :(  When this happened earlier, a reset fixed it, but now I have reset/switched kueypads entirely several times, but the touchpad keys won't work.  The only keys affected are the actual touchpad itself.  Other keys (number, alpha) on the touchpad keypad work fine.  Likewise, the clickpad works perfectly fine.  Could Ndless do something that inactivates the OS reading the "keypresses" of the touchpad?  I have not tried resending the OS yet; that might fix this.

I think you should reformat the calc and re-send the OS. By the way, can Ndless modify the OS inside archive? I know it was possible to accidentally do so on flash z80 calcs.

Set the target folder to an empty string, connect, send the documents, save the flash and restart the emulator the usual way.
That worked: Don't hit <Enter>  in the console window to download through the serial port.
The sent documents end up in /My Documents/ and not in any subdiirectory like Examples or MyLib.
You should be able to use the same trick with Ncubate and not have to patch boot2

The file system can be written to, but the original OS image loaded at boot time cannot be changed since it is signed.

Ok thanks for the info.

serial port.
Serial port? ??? I thought the Nspire only supported USB and that serial ports were long gone. ???

It has an internal one, and the emulator can deal with it.
Edit: This is my understanding, at any rate.

There are RS232 pins on the connector on the bottom of the calculator most
people don't use. I am trying to find an aftermarket adapter for this, so
I dont have to solder to the pins to have a serial communication with the calculator.

Oh, that's the serial port being talked about. I personally thought of serial ports as something like this: :P



I even have a TI link cable for that port that came with my 83+ Silver Edition

Thats right. The other end of the cable will be a DB9 male or female like
you have shown above to connect to a computer. Hackspire and yAronet have some circuit diagrams .
ExtendeD has a RS232 to USB converter - I think , that makes it more convenient to use .

Tomorrow, I'll have some time.
Is there any file to modify for CAS support ? Same than before ? (I haven't looked yet)

edit : Before going to bed I've looked up:

file (number of adresses to get)
bootstrapper.S (1)
install.c (2)
stage2.c (1)
syscalls_cas_2_0_1.c (inf)
syscalls_light_cas_2_0_1.c (inf)
utils.c (2)

Levak: the lines to update are marked with the keyword "OS-specific" in the source code.
I have committed the support for CAS 2.0.1, but there is a memory leak after the installation which make the calculator unusable, I need to figure this out.

DJ Omnimaga: it looks like this on the calculator side.

One bug fixed:
bootstrapper.S CAS line should look like this:
.long 0x101EBAA0, 0x101ebba4

Now hello.tns,particles.tns, NES game,console.tns all work.
ndless_tests  fails - very likely a bug in syscalls_cas_2_0_1.c

It seems there is another missed adress you forgot to mention, I still have the Nspire CAS rebooting after 2 clock' turn.
Otherwise, the Nspire should not reboot. =)
