| ---help--- |
| 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. |
