It was a while ago now but I think it was a bit of both. I particularly
remember trying to set breakpoints and it seemed that the code would execute
without ever stopping at the breakpoints.
I've just had a quick revisit and played with it using the simulator target.
I'm impressed again :) It didn't playup and it broke at every breakpoint.
I noticed that I too had link errors for crt0 so I used -msim. This implies
that my other tests on our hardware was using the -mads option which may have
been the cause of the problems I was seeing. Alternatively, I do have access
to a Motorola ADS board and I may have tried with that piece of hardware but it
is so long ago now that I can't quite remember.

That would be very cool. There are quite a few people using BDM for Motorola
processors. This would also be good the these embedded systems running eCos.
I tried using the BDM with a Linux port to the MPC860 but it died. The gurus
on the powerpc-linux mailing list said it is impossible to use the BDM with
Linux due to its virtual memory management etc.
Brendan.
