Hi,
I'm working on the evalboard of the STM32H563. With a plain project I'm able to activate the memory mapped mode of a plugged nor-flash.
If I change the project to have Trustzone activated and divided the application in secure/non-secure part, I'm not able to activate the memory mapped mode. The communication to the flash is basically working because I can read the ID. The hal functions don't give any error, so I expect that everything should work.
Has anybody an idea what the problem can be?
Best regards,
Stefan
