I'm somewhat a Linux noob, so...
How do you start Linux on the new bootloader?
It confused me too first time. You can find the readme here: https://github.com/tangrs/nspire-linux-loader2
First you need the files: initrd.tns, zImage.tns and bootloader2.tns. Put those in a folder and run bootloader. To boot linux, do "kernel <path to zImage.tns>" followed by "initrd <path to initrd.tns>" and finally "boot" (all without the quotes ofc) I also suggest reading the readme, which I did not at first XD

ARM seems to be a second-class citizen in TCC, and last I checked, TCC wasn't actively maintained anymore.

FWIW, the buildroot config I posted contains Lua compiler, interpreter and LuaJIT (but not some extra libraries) :)
MicroPerl shouldn't consume much space either.



Didn't it also include gcc? How did it end up being only ~8MB?

Nope, it did not include GCC on the target filesystem.

Arg, accidentally deleted my last post.

Compiled the image, only 30MB :)

Has lua, microperl, and some libraries.

I'll upload it later on after I am done with my schoolwork.

EDIT: Dang it, i only get a colorful screen of garbage when I boot it. (Using the pre made zImage)

The kernel image posted somewhere above should do the job :)

Got my image working. Has lua and nano

Log in is a bit messed up, the user is "default"

Lua works nicely, including io stuff.

I attached the image for people who want it.

Also, note for others who want to build their own image, change the default getty console from "ttyS0" to "tty0", so login will work.

Does this work for the Ti-nspire CX? If not is there anyway to get it working on a Ti-nspire CX?

It definitely works on the CX CAS, it might work on the regular CX, don't really know. It's worth a try.

Noob question: how do I exit this?

edit: never-mind, you have to type exit. I feel like an idiot -_-

It works fine on a normal CX, though if using nover too it seems to fail. To me it always fails if I have my nspire overclocked. It hangs on the "keyboard p2/ mouse" message (don't know the exact message, but that one)

Weird? overclocking shouldn't have any effect on running programs (except that they run faster)

Overclocking shouldn't kill anything :S

Are you sure you used the latest kernel? The first kernel has a bug where it freezes when you touch the touchpad.

For the cool factor :) Why else do we program stuff for calculators? :P

Though, eventually, I would love it to have a OSS CAS software replacement. But that's a while away :P

I've have had plans for that for some time now, even before Nspire Linux was there.

Hopefully, I can get Python to compile and run, though I think it might be too big. Can't hurt to try it :)

Currently, it fails on compiling the unicodeobject.h file, don't know why, something about variable declaration errors.

Python 2.7 on an Nspire, now THAT would be cool.
