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.
