Hi
The good news : I can explain you BDI2000 problem :)
Thank you for the explanation.
The bad news : AFAIK you can't fix it :( There is a bug in the rev <= 1.2 of the silicon of MPC5200 : When there is another XLB Master active (like USB or any bestcomm activity), the XLB arbiter can get confused during debugging and you can resume nor can you access memory or do anything ... you can just reboot.
Hmm, this is not good. :( How can I determine the silicon rev.? I'll look it up in the docs.
It's VERY frustrating since the BDI2000 is then kind of useless for debug in the cases when you need those activated ...
So I have to disable USB (can live without it for debugging), bestcomm (hmm, how can I use console on serial port then?) and what else? Thanks again for the explanation, I'd spent one more week on this. Now I know I have to use a different approach :-( BR, Matej
