Connecting to powerpc target via wiggler.

Has anybody been successful in connecting to the powerpc board
using the BDM wiggler from MACRAIGOR system?

I have gdb-5.0 which I have compiled with OCD and BDM4GDB targets.

I am unable to connect to the ocd using command like

	target ocd wiggler /dev/parport0

I have also tried building the BDM4GDB and connecting using
that target, without any luck.

AFAIK Macraigor sells some MS-Windows code that makes the wiggler work
with the MS-Windows versions of GDB. I searched the web some months ago if
someome succeeded using powerpc board, wiggler, GDB and linux but it seems
there is no (free) solution available.
