STM32MP133C- writing to ETZPC from baremetal
Hello! I've been fighting with the MP13 for a couple months now in trying to enable reading/writing to the NAND, as well as configuring ethernet and keep running into issues with being unable to update the necessary registers for this.
When writing to the extended truztone protection registers, no change is made. The clock's enabled, so that shouldn't be it. Within the reference manual, it states "ETZPC registers are write-secure (that is, read accesses are allowed by secure and non-secure domains, write accesses are allowed by the secure domain only". I've yet to figure out how to be in the "secure" domain to update these bits so I can actually use most of the features of this board without using Digi's yocto builds.
Any thoughts/advice on the above?
