Right. I think this also might depend on a closed source utility. ??

In February, someone posted on irc about their python gdb stub for the UDK debugger, which sounded promising: https://github.com/night199uk/edk2-gdb-server Unfortunately, I don't think it ever got posted to edk2-devel. -Jordan > I think that's a good idea.
