Looks like the only viable GDB option with the Raven is under Cygwin then;
has anyone had success getting this to work?  The gdb binary in B20 doesn't
appear to include the ocd target, which means configuring it myself...

Alternatively, is there a better option than Macraigor? I know we could wire
up our own BDM interface, but we have budget and I'd like to buy a commercial
one so we can focus on designing our target hardware.

Thanks,
