    Hello,

    Did you possibly write some of the registers before loading the hex file, and only have the hex file configure the remaining registers? If the user has a few registers already configured and wrote only the remaining registers using the HEX file, then the VERIFY OTP function will give a FALSE for that HEX file because the existing OTP register values are not known to the GUI.

    If you include the already configured registers in your hex file and run the Verfiy OTP again, it should pass.

    Regards,
