    XMC4500 Relax Kit only debug with USB, but not by JTAG/SWD Jlink

    Hello,

    I can only program my board by USB, but I want to use Jlink because I already have the power on board.
    In this board there is 2 processors and one for debug, may be it keep priority on debug.

    So I connect it on the connector X5 but when I run the debug on DAVE, an error appear.

    Connecting to J-Link...
    J-Link is connected.
    Firmware: J-Link V10 compiled Jul 23 2018 09:53:14
    Hardware: V10.10
    S/N: 50111665
    Feature(s): GDB
    Checking target voltage...
    Target voltage: 3.04 V
    Listening on TCP/IP port 2331
    Connecting to target...ERROR: Could not find core in Coresight setup
    ERROR: Could not connect to target.
    Target connection failed. GDBServer will be closed...Restoring target state and closing J-Link connection...
    Shutting down...
    Could not connect to target.
    Please check power, connection and settings.



    I run Jlink.exe and try connected by connect

    Hi Milou T,
    Do you have solved it?I have some related questions.
    But I can debug it by SWD, not JTAG.
    I think that The TRST Pin must need pull up.
