Re: bdi2000 debugging

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. :(
 

No kidding ;)

How can I determine the silicon rev.?
I'll look it up in the docs.
 

L25R marking on the top means rev 1.2 IIRC. That's the one I have. Also, 
if you have a
rev 2, you're lucky, I'd like one ;)

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?
 

Serial port console is OK the drivers I know don't use bestcomm. But
USB, Ethernet, IDE, Codec, ....
