  • [SOLVED] Problem with J-Link SWD Isolator


    I have a J-Link Plus device connected to an J-Link SWD Isolator. A green LED and a red LED light up. With the JLink Commander program I execute the command "power on perm" and the two green LEDs light up. When I turn the J-Link Plus off and on, the green LED and the red LED stay on again. This parameter is not saved correctly. Do i have to do something else?


  • Hello,

    Thank you for your inquiry.
    What exactly is the unexpected behaviour?
    When turning J-Link off and on after power on perm, how many green LEDs are lighting up?
    What J-Link software version are you running?
    Could you post a screenshot of the commander output when your are executing the command?
