I have used the gdb-stub for sparc targets to implement a simple
monitor that can be used to debug RTEMS applications on a remote
target. There were three issues that required some attention:

1. How to halt all timers when a breakpoint is reached and 
   re-enable them when control is given back to the application.

2. How to insert the breakpoint trap-handlers into the trap table
   of the RTEMS program.

3. How to setup the UART interrupt handler so that a 'break-in'
   is possible when typing Ctrl-C in gdb.


Feel free to mail me directly for more details.

Regards, Jiri.
