It seem to run but it did crash or play up quite often.

It IS set up to do normal gdb remote protocol stuff. It is also setup to do some other kinds of DLL based remote debugging. It would be pretty straight-forward to add support for the BDM to Insight, and I will be happy to help anyone who wants to do so get started. > The only way to target the wiggler BDM > was to go to the gdb command prompt and type the usual setup stuff (eg. > "ocd wiggler lpt").
