  • [SOLVED] How to reactivate the message box


    In testing the option bytes to set protection level for STM32L151 chip, I checked the pop-up message box 'Do not show this again'. This caused the chip to be unsecured automatically every time I perform a memory read. How do I undo this action? I am running J-Flash v5.10k.


  • Hi Henry,

    The dialog selection is saved in the Windows registry:
    HKEY_CURRENT_USER -> Software -> SEGGER -> J-Link -> "DontShowAgainUnlockSTM"

    To re-enable the message box, simply change the registry key value of "DontShowAgainUnlockSTM" from "1" to "0".
