ARMv7: Default Memory map in case Write-Through is not supported

Peter Happ

Hello,

I am currently having a strange behavior when disabling the MPU and now I am wondering about one point there.

In the default memory map of the ARMv7 there are memory regions that use "Write-Through Cacheable" in case cache is enabled and default memory is used.

Now the Cortex-R7 that, does not support Write-Through:

My question is: What is the caching strategy for the Cortex-R7 for the memory regions that would in the default memory map be "Write-Through Cacheable".

Thanks and regards,

Peter
