No, I never had this machine. If I had a few, I won't mind doing in-depth analysis of the hardware though (but if there's anyone else who would like to do this, I'd pass on it ;-) ). > 2. what (if any) arcNumber do I have to pass to U-boot for the mainline > kernel to boot? Did you compile the mainline linux kernel for correct machine ? Don't forget this is ARM, the platform setup is pretty much fixed. That's mostly why you pass machine ID. > 3. how do I get the booting process to show on my screen (I mean pre-linux > kernel, just the u-boot messages), cause now the screen stays black and I > can't debug the errors Well u-boot should have serial console working.
