[MPC5777C] MMU vs dual core

[ORaissouni]

Hi all,

I have a short/simple question.
-The MMU entries configuration, is it one shared configuration among the both cores (core 0 and core 1) or is it a core specific configuration ?
- In case it is is a core specific configuration, could one modify the core 1 MMU entries from code executed from core 0 ?

thank you for the quick reply

Hi @ORaissouni 

Each core has own MMU:

A core can acccess only own MMU. It's done via core registers (MAS0 - MAS6) and via asm instructions (like tlbwe - TLB write entry). There's no way to initialize MMU of core 1 by core 0.
