Hi list,
I am playing with an embedded system based on an IBM PPC 405GP. So far I made
the kernel boot, but it gets stuck after running the the init process
(busybox). Any hints?
I notice that ShowRegs does not output anything, and I traced this behavior to
pt_regs passed as NULL in the serial irq routine. Is this normal?
Thank you,
tavi
