Hello All ! I'm new in embedded linux and trying to run linux (2.4.22) on PowerPC (405GP). It boots nice, but when it tries to execute /sbin/init it hangs. Last console messages are: ....... VFS: Mounted root (nfs filesystem). Freeing unused kernel memory: 56k init 4k prep
I've tried to replace /sbin/init by my own executable - it's definitely have not been executed. I've traced it to the "last point" in kernel-mode (instruction "rfi" in file arch/ppc/kernel/entry.S:389). Everything OK before this point. But after this step kernel just hangs. After this sysrq-t prints that process init are running at c0007190 (this is in the arch_kernel_thread). sysrq-p doesn't print any registers, just the line "SysRq : Show Regs".
Could someone give me any tips how to handle this trouble?
