You could assign a known virtual address to the physical address you want to
view.  You can then dump that virtual address to see the physical contents.

Subject: SPI bus on MPC8xx


I'd like to know if somebody know how to debug physical addresses via
bdigdb ( on a MPC8XX  the dual port RAM of the CPM for example) because
bdi always translate adresses to physical one and when i need to access
physical addresses i can't.
Is it possible to force some space addresses not to be translated by bdi
or not ? ( i have looked the bdi user manual and did not find anything

thanks you
