News / Re: Help our community by being a good example
« on: April 08, 2011, 07:14:41 pm »
I personally haven't seen any of the Omni directed insults or bashing recently and I think much of the issue is rumors and just  general distrust. And any negativity seems to be both ways. There are many people who do visit both sites and I don't really see this a being a real issue.

I do have to mention that I am not too comfortable with the line "If #cemetech can get away with this, it's their website, let them do what they want." being on your sites front page. It seems like you are implying that our IRC channel is the only one this is going on in and that it is not in fact bidirectional. I would much prefer if the "FULL ARGUMENT" part was at least removed from the front page as to shorten the article and to not seem be claiming your IRC channel does not have its own issues.

And what are you trying to send, to which calc, and with what cable.

PK is part of the zip file header so that is expected with a zip.

Just to clear things up a Silverlink version is nigh impossible as the Silverlink speaks TI's OI protocol and CalcNet is an entirely different beast. Its like trying to Japanese to a Frenchman, it just doesn't work. Kerm could send calcnet packets via TI's protocol but it would require more PC side code and be a mess to handle.

Casio PRIZM / Re: Compiling stuff for Prizm

I actually have my own built toolchain I built based on GCC as I didn't want to register to dl the one from that KPIT site. It can be found at http://jonimoose.net/prizm/sh3-unknown-elf/ the two tars are identical one just used xz compression to be smaller.

I've started reading http://www.glomationinc.com/PortingLinuxKernel.pdf which seems to be a good starting place and so far has confirmed what I thought was the case when it comes to kernel side things. We'll want to see if the Nspire is similar enough to any existing machine types to base our work off we'll have to work from scratch but that doesn't seem to be as big of deal as I originally thought. Give this a read if your interested in helping as it seems to have very relevant info.

Well sadly its not just the processor, its the memory layout, peripheral chips, LCD, USB controller that we have to worry about, but the more I look into it the more sense starting from scratch seems to make, but that may just be me being tired. Once we have a way to boot things we'll know more.

Just to get an idea of how many different Arm based Linux machine types there are and why getting Linux on an Arm device is harder than just installing via Live CD on a desktop here is a nice list of all the registered "machine types" most of which are not or may never have been supported by the mainline Linux kernel. http://www.arm.linux.org.uk/developer/machines/

But hopefully one of those is close to what we need, if not we'll have to start from scratch which may not be the end of the world, just means harder work, but it maybe less in the end depending on the situation.

Some quick googling came up with this as a good place to look at getting a bootloader setup. Someone familiar with ndless programming could look into implementing something based on this via an ndless program, assuming we have enough access to the hardware to do so.

http://www.simtec.co.uk/products/SWLINUX/files/booting_article.html

Ok thanks I will look into that, the patch that adds support for that board to the kernel is here http://www.phytec.com/products/linux/bsp-LPC3180.html I have started to look through it to get an idea of where we will want to start. Sadly it seems the patch contains a large amount of useless content and is for a rather old kernel version but its better than nothing, thanks.

Also again sorry for any harshness, but I felt I needed to define what was constructive was in relation to this thread.

DJ my point was I wanted to see if we had the combined knowledge and manpower to do this before we had a 20 page thread about it. If and when things get going a 20 page thread+ML+wiki etc would be in order but I want to try and keep things organized since the first thing we need is a kernel and a bootloader then that is all the should focus on. Anything else is unneeded.

As I said our first step is to see if we can find a platform similar to the Nspire that already has Linux support, if none such device exists much more research will need to be done. I personally don't have the time to do this but I will assist if there is someone willing and knowledgeable enough to take the reigns.

For me PoC would be getting the kernel to spit something out on either the LCD or the rs-232 lines if we can get that then the rest will follow. The hard part is getting the ball rolling/the kernel booting, its mostly down hill from there thanks to the likes of angstrom and similar embedded Linux distros.

To clarify this thread should be about getting the Linux kernel booting on the Nspire if you don't know what that means or you are not familiar with the Nspire hardware, ARM devices in general, the linux kernel, or arm bootloaders than this thread is not of interest to you. If you cannot contribute in one of those areas please keep this thread clear of unneeded cruft. Encouragement and questions are good except when they drown out the conversation and content the thread is intended to contain.

DJ_O that is out of scope of this thread. Once we have a working kernel we can decide those logistics but without the kernel any other speculation of how things will work is pointless.

But in response to your question:
For booting Linux on a Windows Mobile device you can either install linux to replace Windows Mobile or you can use what is called a chain loader to boot Linux from Windows Mobile so that you can still use both, we'd most likely go with this second option.

I know nothing about the hardware itself other than it is arm9 so while I am willing to poke at the kernel a bit we'll need someone who is more of an expert on the hardware to at least point us in the right direction.

hackenspire has a lot of good information but finding at least what arm "platform" it is based off of will give me a starting point for linux. If it is entirely custom then we might as well stop here as I personally don't have enough knowledge nor the time to start from the ground up and nor does anyone else here afaik.

Step 1 and 3 are the big things, we can choose a distro or roll our own once we have something booting.

If we can find a similar board with at least close memory mapping and hardware we will save huge amounts of time and work. Currently afaik non of us know enough to start from scratch so this is where I think we should start.

Edit: Also lets keep this thread about the kernel and bootloader, we can figure out where to put the rootfs later.

Also space concerns on a non issue, busybox easily fits on routers with 2MB's of flash we so we have plenty of space.
