  • [SOLVED] J-Link: VTREF has to be powered on at each start

    Hello,

    I just received a new "Segger J-link Base"
    In JlinkExe, I entered "Power On -perm" command that allow to have VTref=3V and power on our device
    But I have to enter this command each time I plug the Jlink on my computer, otherwise VTref=0
    I was expecting the -perm option to get rid of that (ie I have only to do it once), but I guess there is another command?

    Thanks for your support
    Regards,
    François
  • Hello Francois,

    Thank you for your inquiry.
    The correct command is "power on perm" without the "-".
    Then it should work as expected.

    Best regards,
    Nino
