I'll try to see what happens when the image is moved now that I know this might be the problem, but my stupid debugger isn't friendly at all and it's very difficult to do so. I tought the image wouldn't be moved if I placed it a address 0. I copy my zvmlinux.initrd at this address so I tought it wouldn't be used. This is indeed a custom board and I'm really just dropping vmlinux at address 0. I also found out that the values of initrd_start and initrd_end aren't valid when assigned from r4 and r5, so something must be overwriting these values (intrd_end is smaller than initrd_start) What's the use for r3? I read it's board identification but I don't really care if my board isn't identified correctly (for now at least). A looked for documentation about this but couldn't find any (the booting process of linux on a PowerPc seems to be terribly undocumented) Thanks for your help, S?bastien C?t? ** Sent via the linuxppc-embedded mail list.
