DE0 Nano uclinux

[Charles Manning]

They'll be using ucLinux because full-fat Linux requires a MMU.

Wayhoo! Thanks for the inspiration!

If anybody is using Windows, and want to get it up and running real quick using a prebuilt configuration...

Download 'DE0-nano.sof' and 'zImage' from http://www.ccm.ece.vt.edu/usvn/svn/alteraApps/trunk/uClinux/precompiled/DE0-Nano/

Launch "Nios II 11.0sp1 Command Shell" (or equivalent version)

bash-3.1$ nios2-configure-sof /cygdrive/c/Users/<username>/Downloads/DE0_Nano.sof
...
bash-3.1$ nios2-download -g /cygdrive/c/Users/<username>/Downloads/zImage
...
bash-3.1$ nios2-terminal.sh
nios2-terminal: connected to hardware target using JTAG UART on cable
nios2-terminal: "USB-Blaster [USB-0]", device 1, instance 0
nios2-terminal: (Use the IDE stop button or Ctrl-C to terminate)

Finally after a full night of pratting around and a lot of Internet
bandwidth I have got the following combination working:

- Quartus 11.0sp1
- Fedora 14 x64
- All running in Virtual Box

I can now build a full set of SPOC hardware and zImage from source. Big
problem was you need 'make-3.81' from Fedora 13 for it to work.

If anybody wants a copy of the VM let me know - it's about 40GB.

Hi,

I've finished my write-up on how to get it working at
http://ec2-122-248-210-243.ap-southeast-1.compute.amazonaws.com/mediawiki/index.php/UClinux_for_Terasic_DE0-nano_on_Fedora_14,
if anybody wants to "give it a go".

Be warned, the 'svn' checkout is about 1.8GB....
