Barebox and the kernel are in = the NOR flash.

I’ve = successfully booted the exact uImage using u-boot v1, so I’m = fairly confident it’s OK.

Any = suggestions of what could be wrong?

The machine arch # is correct. The tagged list looks = correct (gdb mem dump just before calling theKernel()).

Guessing = something is not being inited as required. Or I’ve done something = silly.

I assume other people have booted successfully on = this board. (Any known working kernel images would be great to test = against!)

Hints greatly appreciated.

Cheers,

Marc

Great tip. It shows the kernel is starting ok and getting stuck just after irqs are enabled. I'm still a bit baffled as to why this only happens with barebox.

I have just tested 2.6.31 and 2.6.34-rc-something on my board, both working fine. Maybe this has something to do with the clocks. You could check the register values of the CCM module in barebox and U-Boot (md 0x53f80000+0x80). Also note this mail: http://lists.infradead.org/pipermail/linux-arm-kernel/2010-April/012691.html I suspect a bug in the kernel there which is still present.
