  • [SOLVED ]How to verify if a chip being secured

    Any recommended method to verify if STM32 and nRF51822 being secured?


    Perform Blank Check or Read Back an secured STM32 and nRF51822 with J-Flash and J-Link Plus?
  • Hi,


    depends on the target device and level of security.
    E.g. on NXP Kinetis devices the and ST STM32 devices the security settings can always be accessed / read via the debug interface,
    as long as the pins of the debug interface are not disabled.


    Best regards,
    Niklas
