Why is it necessary to disable the MPU when reading/writing to an SD Card?

Question asked by Manuel Malagon on Mar 20, 2017

Hello everybody

 

I'm looking at the code for reading/writing to an SD card, particularly in the FRDM-K64F board. I notice that the code contains the statement "MPU_Enable (MPU, false);" which at the best of my knowledge, disables the MPU.

 

So I would like to ask why is this necessary?
