    XMC Debug LED blinking

    Hey Guys,
    I just got my ordered xmc 4500 Relax Kit Lite.
    Unfortunately when I plug the board (both sides) into my laptop (Win10) the debug LED keeps blinking fast.
    The Power LED is normal. What does that mean?
    Dave Version 3.1.10 installed & JlinkARM_V484 installed as well.
    J-Link commander doesn‘t find the board as well. Already tried different micro usb cables.

    Do you guys have any idea about my problem?

    Thank you guys,
    Best regards

    Can you try using only the USB debugger connector?
    You should see the Power and Debug LEDs on.
    Update JLink to latest version, i.e. v6.80b
    Try now with JLink commander.
    You should see:
