Do you use defconfig as kernel?
tangrs didn't enable CONFIG_LBDAF, so you can't mount ext4 r/w.

That was the only thing I changed. Other than that, is there anything I need to do?

Nope, It should work fine by now.
Could you post the full error messages in "nspire linux questions"?

I've just enabled CONFIG_LBDAF in the defconfig.

Oh, almost forgot that one. Yep, committed!

So, after all of this hard work, what can you do on Linux?  You use 80% of the available RAM so you can do what with it?  Run small programs on it?

You can run X. You can compile C code. You can even run graphical web browsers, but that's really slow. (Command line ones are faster)

oh OK, still not very appealing to me until you make a video showing all of the cool stuff you can do on it.

So, after all of this hard work, what can you do on Linux? 

Pretty much anything you can do normally on a desktop Linux distro.

You'd be surprised to know that Linux only uses about 8MB of RAM on my development build (potentially much lower without a ramdisk) which works out to be about 13% of the total available RAM on CX models (about 25% on the classic models). Nothing close to your estimate of 80%.

Of course, by today's desktop/laptop/mobile/tablet standards, the remaining 56MB wouldn't be enough to run anything. But in this case, we're talking about an embedded device running low overhead applications. In the embedded world of computing, 56MB is actually a huge amount of free memory with lots of potential. For example, I have in the past, ran a X server with Xterm, Xclock, Xeyes, Mathomatic open and plot a graph with GNUplot all at the same time with still plenty of RAM to spare.

Sure, if that's what you want :)

Don't forget that we're aren't a corporation or business trying to 'sell' Nspire Linux. I ported Linux to the Nspire simply because I could and it's something I can enjoy working on. I didn't and still don't think about how this could be useful at all when I develop for it. Plus, I learned a ton about kernel development on the way.

And come on, when was there ever a time when Linux being ported to a new platform wasn't cool? :P

oh OK, still not very appealing to me until you make a video showing all of the cool stuff you can do on it. 

It's totally cool if you don't find it appealing. I understand that not everyone sees things that same way as some of us do.

As developers, we generally engage more with the people who are more interested in our work but, for the heck of it, here's a few videos from the past that shows some interesting things with Linux

@tangrs I find all of your responses valid, thank you for your thorough reply.  Linux on a calculator is pretty cool.

No, you can't run Crysis on a calculator. (Assuming running Crysis is what you mean by appealing)

I can run a video of crysis....:P

I wonder how hard it would be to get a VNC client running. That would enable a lot of really cool tricks.

I am having an issue with the new kernels. I have a working version of Linux using an initrd, an older busybox kernel, and bootloader2. (there is only one version of bootloader2, right?) I recently downloaded the two kernels and tried to boot them both with and without a USB-OTG setup and script, every atempt failed to boot past the bootloader screen. I anyone wants to see the boot script I can post it. I would apreciate any help with this.

EDIT: Posted on next page.

I support this kind of hacking: making things do things that those things weren't originally meant to do.

Can you post your bootscript and make sure you have the latest kernel?
