what o.o
do you mean you are making linux for the TI-nspire?

Yep. Well hopefully

Wow awesome o_O
Coming from such a talented developer as you are, you will surely get some more people interested and I truly hope this is going to be a great step towards ... a new world ?

(also, you should modify the topic title to make it more attractive )


EDIT : cross-posted/newsed on tiplanet

btw tangrs : you're using XCode for nspire dev too ?

No, I usually just use a simple text editor

So any chances that this will be available for the non-cas ever?

I believe that's not a problem
(However, CX is probably a pre-requisite)

It's CX only right now because that's the only hardware I have right now to test on. I've found that the nspire emulator can't emulate some of the instructions Linux uses (especially to do with caches) so I actually need real devices to test on.

It is definitely possible to make it work on the older calculators - there's no reason why it wouldn't work. Linux only needs ~4MB of RAM which even the old calculators have plenty of.

Extremely interesting
Of course you should upload the source code (of the kernel, device tree definitions, U-Boot, etc.) somewhere in public, tangrs

Note that a Linux port for the Clickpad series would be even much more interesting than a port for the CX series, because on the Clickpad series, it is certainly possible to install Linux permanently (because it is definitely possible to change the contents of the boot1), and thereby be completely free of whatever lockdown TI will try - and fail, as usual - to put forth (instead of embracing developers and making its calculator more useful as a result)

And indeed, CAS vs. non-CAS (especially on the CX, which does not have interchangeable keyboards) is, for all practical purposes, only a difference of several bits in the ASIC ("CAS bit" and two leading hex digits of the product ID), as shown by RunOS (never released, in 2010) and OSLauncher (independently reimplemented, and released, in 2011).

Alright. In that case, I'll post up sources some time tonight - but beware! I'm new to kernel developing and the code is quite messy to say the least.
