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.
