  • [SOLVED] Unable to unlock debug port EFR32FG23

    I cannot unlock the debug port from the EFR32FG23A from Silicon Labs.

    I have noticed there is an "unlock" command with compatibility for EFM32Gxxx devices.

    I was wondering if there will be a unlock feature for the EFR32FG23A soon.

    I am also wondering if this unlock feature will be available in JFlash, so we can update devices with old software in production.

  • Hi,
    Thank you for your inquiry.

    The Unlock command is a legacy command.
    By now, the unlock will be executed by default on connect,
    however it is not implemented for all devices (same for J-Flash).

    For the EFR32FG23A, no special connect has been implemented, so you would have to do so yourself.

    The way to go here would be to use a J-Link Script File with an InitTarget() function.
    Within this function, you would have to unlock the the device.

    I added the native unlock to our feature request list, however I cannot provide any timeline for this,
    as we are currently pretty much booked.

    Best regards,
    Fabian
