BDM/OCD with Macraigor Raven on MPC8xx from x86

I'm wondering if anyone has had any success using gdb from an Linux x86
machine to debug an MPC8xx target via BDM using a Macraigor Raven OCDemon?

I've looked in the mailing list archives, and only found mention of using a
Windoze host with a Wiggler. I'm not keen on switching to Windoze, and would
like to take advantage of the Raven's extra speed if possible. Any pointers
greatly appreciated!

Thanks,
Graham

Can not be done.

Macraigor will not release the specification to enable GDB to interface
directly to their OCD Debuggers. The only support is through the
Macraigor supplied DLL, and that only runs under windows. If you can get
the specs for their devices then you can always write the interface from
linux :).

Im building my own interface, specifically for Linux/GDB because of
this. When it's available i'll post to the list.

I am building something (I call it labslave) like gdbserver, only for
embedded environment. So, one can run this labslave on NT talking to
Macraigor DLL one side, while communicating with remote GDB over standard
remote protocol on anther side.. Current version is 0.1 and the only
target supported is 'remote' (and I am looking for pre-beta testers).
