MPC5777M: How to ensure shared memory coherency

Hello all, 

 

We are writing an application requiring shared memory berween core and cache enabled (for perfomance issue). 

The memory will be updated by two ways: The classical one (store memory) and DMA. 

 

 

I don't know how to ensure cache coherency in these cases. Is someone can help us?

 

Thanks for you help.
