STM32h573 read OTP

[CHeck.1]

Hello,
I'm trying to read the OTP flash form my application but I get a hardfault.

Is there a read protection or something like that?

 Here is a code snippet:

#define FLASH_START_ADDRESS 0x08FFF000

int main(void) {
 HAL_Init();

 uint32_t* flash_data = (uint32_t*)FLASH_START_ADDRESS;

 uint32_t data = *flash_data;

maybe....from rm :

I think that should not result in a hard fault
