use bdi on board with ppcbug

hi!
I want to debug the kernel on the motorola lopec p011 board with bdi tools.
And the first thing I must solve is to let the ppcbug "go" under the bdi control.But I don't know where the entry of ppcbug is,so I can't "go" the ppcbug.Has anybody know that?Or,the ppcbug can not be run under this circumstances?

Wait for your reply?
Thanks in advance!

Just type "reset", followed by "go".

Like any other boot loader, ppcbug will strat right from the reset vector.

Best regards,

Wouldn't it be the PowerPC reset address - 0xFFF00100?

0xFFF00100 is just one out of several possibilities, depending on CPU type and system configuration.

to see where your boot code starts:

at the BDI prompt the command:
reset halt <enter>
followed by the command
info <enter>

BDI responds with:

Target state : debug mode
Debug entry cause : debug port nonm
maskable breakpoint
Current PC : 0xfff00100

current pc is where your boot code starts
hope this helps
