I never got this to work well. Also, it is quite old and cannot be 
easily ported to more recent
versions of GDB.

Therefore, I decided to implement my own version based on the GDB 
'remote' protocol.
It has the additional advantage that you can either use a serial line 
(useful if you want
to debug a network driver or networking related code) or a  TCP connection.

You find it at

Source-level debugging. Also, even if your board has a firmware monitor 
that is not necessarily
gonna work -- some RTEMS BSPs take over the entire machine and change memory
and/or exception vectors etc. in a way incompatible with the monitor.
