stm32h747: XIP from external SDRAM

Is it possible to run the firmware from an external SDRAM?

There is an example for h750, but it does not work with h747.

I go to the address I need, but I get a hardfault into bootloader for first command into external sdram

Hello

External SDRAM is execute disabled by default.

The MPU can override the default memory access.

Need to configure SDRAM region in MPU with XN bit at RASR register, disabled.
