Problem with access permission for on-chip peripheral on STM32MP257F

Hello

We are using the STM32MP257F in M33TDCID flavour using the package

stm32mp2-m33td-openstlinux-6.6-yocto-scarthgap-mpu-v25.06.11

We can boot and run the Non Secure application, but when we try to use some of the peripherals (I2C, SPI, GPIO)

we see processor exceptions or Resource Manager issues.

How do we configure the device to allow the Non-Secure application access to all the peripherals

Thanks
