Hi all,


I would like to know more about the GDB Server inside RTEMS. I read about
the work from people at Canon, but I still have some questions:

1) Do this GDB Server works only for Intel and PowerPC BSPs?

2) How can I enable and use it?


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

3) What are the advantages over a regular monitor software ? (this one is to
convince my bosses ;)


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.
