Hi,
I'm porting Linux 2.6.12 to a MIPS 4KEC based SOC.
I have do some essential setup work, include CPU setup,
board setup, interrupt initialization, page table setup, etc.
In breaf, it can go through the kernel initialization code in "
main.c"
until it try to open "/sbin/init " file, here is the source code:
if (execute_command)
run_init_process(execute_command);
run_init_process("/sbin/init");
run_init_process("/etc/init");
run_init_process("/bin/init");
run_init_process("/bin/sh");
"run_init_process(execute_command);" calls "execve" which is a
system call, then the kernel stopped without any information.
In trap_init( ), kernel has already installed exception vector, now
I cann't find the problem, can anyone give me some advices?
Thank you very much!
