Actually, the "port" was my sending a copy of the SH-2 stub to someone who was
working on PPC.  They promised to port it and return, but I never heard back
from them.

You can now find the complete SH-2 stub at www.sourceforge.net.  Do a search
for "gdbstubs".

It's a complete rewrite from the ESP days, designed for more portability.


If you're familiar with the PPC, then you could always do the port yourself.
eCos has a stub as well, and it shouldn't be too hard to meld it into my
sources.  I don't have any PPC hardware, though, so I'm understandably wary of
trying to offer much help with the hardware-specific stuff.  If I had the
hardware, though...

You can try the thing I put togehter at
http://www.std.com/qqi/labslave/rproxy.html

Among other things it provides an application bridge between
wiggler (BDM debugger from macraigor) and gdb remote protocol.

Yes, that's an even better solution than a stub, on targets and platforms that can
support it, becuase it does in hardware what the stub does in software.
