I'm working on H745 dualcore MCU and I'm trying to get STM32 UID from M4 core accessing to addres 0x1FF1E800UL. Reading datasheet I can't find explanation why that address range is not accessible.

Hello @Community member​,

Indeed, these fields are not accessible via CM4. You need to copy it using CM7 elsewhere so that you can access it through CM4.

Hope this helps!
