hi, zhangfx,
thank you for your reply, I added printf to the init.c file of
android file system code (system/core/init/init.c), and found that the
kernel panic after the "open_devnull_stdio" is called, so I think the
kernle panic in that function, I will check the exact point the error
arise.
as you said " For illegal instructions,you can add printk in arch/
mips/kernal/traps do_ri entrance", did you mean whenever illegal
instructions executed, the do_ri function will be called?
