WOW, this is unexpected. Well done! How does it run? I assume it's not really at a usable speed.

I do wonder why "Minor compilation changes for older GCC versions" was necessary, binary literals have been supported since ages.
You should definitely update your SDK and toolchain!

Boot up is slow, taking ~3-5 minutes (Although I believe I can speed it up), but after most of the core services are starting the system is actually pretty usable (imagine an HTC Dream running at half-speed), making this a feasible alternative OS to run on the calculator.

And regarding the whole "Minor compilation changes for older GCC versions" commit, I at first (embarrassingly) set my $PATH to the wrong arm GCC toolchain location (which I originally thought was the ndless SDK location). After I fixed that, the whole commit was rather useless but I figured I wouldn't revert it just in case...

This is awesome! Where is the rootfs stored? I assume it's on an external flashdrive or something.

Until NAND drivers are working on the new kernel, I opted to put the rootfs on an external USB drive via usb-otg. It currently uses 4 partitions, one for the system, one for userdata, one for the cache, and one for the virtual sd card.

Here's a demo video as well:

Thanks for the video - I updated the TI-Planet article :)
And it actually runs faster than what I would have expected!

I saw this yesterday and also thought it was a joke. That's a lot faster than I would have expected, well done. :)

Can this run Android?

Theoretically, yes but it's too much work for it to be worth it.

Oops



My my! Touche!

Congratulations! That is absolutely amazing!

This was just brought to my attention and I believe news is in order. I'm a bit too busy with work to post one myself but I'll tag a couple people and see which one does it first

i saw this yesterday but didn't realise it was a huge deal. what had to be done to get it running on top of linux stuff? interface drivers? stripping out bloat processes?

Congratulations on this outstanding achievement, joshumax. Saw it on the main German tech news site earlier today ;)

Thank you in advance

Wow, this is soooooo amazing. I did not think you could actually run a game on the android port.  Though, it's not that intensive it it?(Unless that's not on the android port?   :hyper:

Can you describe what's happening while it's loading and where it's freezing? Also, if possible can you send pictures of the problem? I can't really diagnose what's going on without more information...

I posted a video a few posts back of it running the Android SDK game demo "Lunar Lander." (See https://www.youtube.com/watch?v=Skbuc_pQj9g). It can also run games like Snake rather well; other than that the only real limit is the capability of the hardware, which isn't that high-performance to begin with.
