Changing attributes for different memory regions

Discussion created by Zubair Mohiuddin on Jun 11, 2019

Hi Experts,

 

Is it possible to change the memory attributes for different memory regions for Cortex-M4 core in HALO processor MAC57d5xx?

As mentioned in the reference manual, the default attributes for different regions for ex: DRAM is WBWA, i want to try to change this area to non-cacheable instead being cacheable, so is there a way? i don't find anything in the reference manual.

There is no MMU but MPU for M4 core.

 

Or simply there is no way to control cacheability attributes of different address space regions for HALO CM4, right?
