oh, didn't know that.

I'm not sure if i understand you correctly, do you refer to
the problem i had seeing the the source code?  That was related
to the return value of "S0" instead of "S00" somehow.

The example provided in the pppcb/examples/arm/eb01 folder
in the package i wrote is the one i'm testing with (except some
minor changes maybe).  I can download it, start it, stop it,
set breakpoints, ..., all with the GDB remote protocol server
i wrote.


Best regards,
Torsten.
