That is the exact same build I was using, that or the one from the 18th.

The latest build just causes my calculator to hard reboot after I run my script... ???
Do I need a new ndless or something?

Yep, I'm using the latest version.
Do you have the latest linuxloader?

I believe I do, i just redownloaded it from tiplanet. Why one kernel would work and the other wouldn't with the same ndless version is beyond me. I guess I'll try updating it (though I swear I just did it not long ago for gpsp)

That would probably also explain the flicker and such.

Edit: Nope, its definitely up to date, the last time ndless was updated was 8/15/2012, and I've definitely updated it since then

Thought so, too, but nTxt didn't work for me.
I'm using ndless v3.1 beta r685.

That's a bug in nTxt's version checker, im pretty sure, i get the same thing.

Nope, it just crashed.
With the last ndless versions it works perfectly.

Im using ndless r985 and it won't even launch for me.

Edit: I'll try reinstalling ndless again, see if that helps. Also the build I used for the kernel was 20130119_1525, and 20130118_1959 for the FS Image

Hmm..
I'll try the exact same configuration as you're using on my calc.

Edit: You're right, it crashes O.o
Now my NAND is corrupt.. f*ck.

Mine freezes on reboot until I hard reset it. Is that what NAND corruption is? Or did I just completely brick your calc? :o

Nope, you didn't xD Sometimes I only need to reboot, but most times I have to run NAND tests in diag mode..

I think it's caused by some accidentally accesses to NAND which makes it lose some data.
I needed to format my NAND completely once..

Ok, so this is basically an issue with the kernel itself, not with my setup. I wish I could help with porting/patching linux stuff, but I'm a newbie with C.

Yes, probably with the cpufreq driver. I hope tangrs implemented the AHB clock limit correctly..

If you don't want to/can't code stuff, you may try to understand the filesystem.
Just open your flash image from nspire_emu in a hex editor.
Maybe you can reverse engineer it, there's currently no open source driver for the filesystem TI uses available.

Edit: Compiled the kernel on my laptop (instead of download it), it works. (Haven't tested X)
Does it work for you, too?

Black-box reverse-engineering of the filesystem is a pain.
The boot2 1.4.1571 for Clickpad/Touchpad has long been known (through strings) to contain lots of filesystem-related code, not only FS interaction code called by the NavNet code, but also testing code.

Haven't done it before, but I think it's too confusing to see weird accesses with apparently no purpose at all.
Maybe it's the best way to compile nspire_emu with nand read/write debugging.

It works for me as well.

The font is very hard to read (its tiny), but it works better, the flicker is there, but MUCH better.

X Windows still won't work, im getting

Code: [Select]
(EE) Failed to load module "fbdev" (module does not exist,0)
(EE) Failed to load module "mouse" (module does not exist, 0)
(EE) Failed to load module "kbd" (module does not exist,0)
