  • Hello,

    Thank you for your inquiry.
    Please be aware that this forum is a community forum so there is no guarantee to receive a response here.

    We tried to reproduce the reported behaviour but everything was working as expected in our example setup.
    See successful connect sequence attached.

    Are you using a RX adapter between J-Link and target device?
    segger.com/products/debug-prob…ries/adapters/rx-adapter/
    or
    segger.com/products/debug-prob…adapters/rx-fine-adapter/


    Are the 5 V VTref expected?

    Could you provide a screenshot of your connect sequence with J-Link Commander?

    Best regards,
