RT1020 & RT1050: How is the MPU configured during boot ?

For the RT1020 and the RT1050:


1. What actually configures the MPU during boot? Is it the ROM bootloader?


2. What memory regions are blocked/enabled during boot for each processor?


It looks to me like the RT1020 has the internal SRAM blocked, but the RT1050 does not.

I cannot see where this is documented.

Please can you expand on this.


Many thanks.
