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. > > This was the very first release of Insight so I put it down to it's > > imaturity.

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.
