How may I use STM32MP257F-EV1 PCIe in *Endpoint Mode*? I am looking to connect two STM32MP257F-EV1 devices together via PCIe; one device in PCIe host mode, and the other in PCIe endpoint mode.1) Physical connectionAccording to the boards user manual...
Accessing memory protection unit for cores in MP2
Does anyone know how to see and set the cacheable status of memory regions in an MP25x series micro? It is very simple for the H755: you pull up the cores in the Cube, and the MPU fields are all there to fill out. The memory regions outlined in the R...
