gdbserver in Board

Assuming you have networking already setup to your target board. Copy gdbserver to it, run:

$ gdbserver --multi :2345

On your development machine, run:

$ arm-linux-gnueabihf-gdb
(gdb) target extended BOARD-IP-ADDR:2345
(gdb) set remote exec-file /bin/true
(gdb) run

and you're up and running with remote cross debugging.
