It should branch to the beginning of arch/ppc/kernel/head_4xx.S, which I think was 0x0. Some things to check are: - Comment/remove the weak embed_config in arch/ppc/boot/simple/misc-embedded.c - Did you use ttyUL0 or ttyS0 as your console? If that fails, you can use XMD to set a breakpoint at 0x0 and then read the memory to see if it matches up with an objdump of vmlinux. _______________________________________________ Linuxppc-embedded mailing list [email protected] https://ozlabs.org/mailman/listinfo/linuxppc-embedded
