Hi,
I'm porting Linux 2.6.12 to a MIPS 4KEC based SOC.
I have done some essential setup work,including CPU setup,
board setup, interrupt initialization, page table setup, etc.
In breaf, it can go through the kernel startup 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( ), it has already installed exception vector,and I cann't
find the problem, can anyone give me some advices?
Thank you very much!
