Can not access memory after turning MMU on

[Freddy Lugo]

Hi,

After turning the MMU (turn_on_mmu) the next memory
access instruction (stwu) can not be translated, the
memory can not be accessed and the system halt.  I
check the list archives and there are references to
set the Debug Enable Register (DER) to an
"appropriate" value.  I am working with the MPC750 and
in the Users Manual I can't find any reference to such
register.  Also I checked my bdi2000 (in case it was a
register on the bdi) and I didn't found anything.

This register exists or has its counterpart on the
MPC750?  Besides the DER value, there are other
methods to work and find the problem?

Thanks,

Freddy Lugo
