Hello,
Is it possible to programmatically enable-disable local bus cache on MPC8347?
Is it possible to check programmatically whether the local bus cache on MPC8347 is enabled?
I will appreciate any help, including a reference to the appropriate documentation.
Regards,

Do you want to disable caching of just the local bus (i.e. let the system still cache the DDR)? If so, then you need to modify your MMU settings (32-bit programming environments manual) and set the cache-inhibited option.
