Hi,

you will turn on the image verification by setting the option flag in the stm32 header (see here: https://wiki.st.com/stm32mpu/wiki/STM32MP15_secure_boot#Image_signing) of the to be checked images (TF-A, U-boot, OP-TEE) to 0. To do so you can use the supplied signing tool: https://wiki.st.com/stm32mpu/wiki/Signing_tool
