As I mentioned before I managed to install a basic linux on the ChipWorkX module. For now it’s just a console version without any output whatsoever on the LCD and you should have access to COM1 (via UART<->RS232/USB) converter. You can alternatively ssh into the board but it’s still best to have console access in case something goes wrong.
If anyone else here on the forum is interested at this stage I will write a small howto (it only takes about 15 minutes to set this up, and you can revert back to the latest GHI firmware in less than 5 minutes) else I’ll wait until I have a more stable solution with graphics, ipkg and (hopefully) sd card support. I’m working on the cross compiler setup under linux right now so I can compile all the components myself and have more liberty over what drivers to add and which software to include.
If there is anyone else working on this please let me know and maybe we can work together…
