Hi, I have a custom board with a stm32mp153. I was able to get past the trusted bootloader and into optee. It builds the mmu map and then panics when checking it. I am able to partially step through building the table and the memory starts to get corrupted but I can't see why. I also have a 157-ev which works fine when I build for that on the same dev machine. I am looking for possible clues on where to go from here.
if you are writing to DDR, maybe double check the correct DM Vs DQ/DQS wirings on your schematics. We had seen similar behavior when customers swapped Data Mask and Bytes which mean x32-bits write works but not bytes.
