I have some questions relate to memory caching in i.MX8 system. I'm working in M4 side


I understand there are two instances/modules for caching

   + MPU in M4 core

   + LMEM in M4 subsystem


Is there any relation between MPU and LMEM. Do they depend on each other?


Is it possible if i enable both MPU and LMEM?

If i configure a DDR region is non-cacheable by MPU and enable LMEM, when i access the memory in non-cacheable region, is the data in the region cached?
