Use the "ps -l" command.  It will give you the Windows PID in addition to the Unix (Cygwin) one.


Start your "top" gdb in a separate shell.  Use the command attach passing the Windows PID (as opposed to the Unix PID) of the other GDB.

You are now debugging your powerpc-motorola-elf-gdb


Good luck.
