Hi!
According to the instructions on page https://wiki.st.com/stm32mpu/wiki/How_to_perform_Secure_Boot_from_Distribution_package#Creating_signature_key_for_STM32MP15x_lines
1.) Problem at 5.1

This may brick your system.
Use this command only if you are sure of what you are doing!
Really perform this fuse programming? <y/N>
