The CRIS version of gdb can be used to remotely debug a running
|
|
Linux kernel via the serial debug port. Provided you have gdb-cris
|
|
installed, run gdb-cris vmlinux, then type
|
|
|
|
(gdb) set remotebaud 115200 <- kgdb uses 115200 as default
|
|
(gdb) target remote /dev/ttyS0 <- maybe you use another port
|
|
|
|
This should connect you to your booted kernel (or boot it now if you
|
|
didn't before). The kernel halts when it boots, waiting for gdb if
|
|
this option is turned on!

If the system locks up without any debug information you can say Y

here to make it possible to dump an OOPS with an external NMI.

Place segfaulting user mode processes on a wait queue instead of
|
|
delivering a terminating SIGSEGV to allow debugging with gdb.
