SPI bus on MPC8xx

Hello,

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 intresting)

thanks you
