Will boot ROM code checks the integrity and authenticity of Secure boot in STM32F769I-DISCO?

On running the SBSFU project on STM32F769I-DISCO board, will the boot ROM evaluate the integrity and authenticity of Secure boot. So that, the user will be sure that his/her Secure boot not replaced by others.

Hello @MdFayaz​,

According to AN5056 In production mode, the Secure Boot checks the Option Byte values (RDP, WRP, PCROP, Secure user memory) and blocks execution in case a wrong configuration is detected. For F7 products, nDBANK must be configured. If this is not done, the device remains unsecured.

Hope this helps!
