  • Hi,

    I'm not able to debug MIMXRT1020-EVK board with P&E Multilink Universal FX. Tried with lowest debug frequency but result is same. Getting P&E Connection assistant window.

    In same board Segger J-link works.

    J25,J26,J27,J28 - All jumper is Open.

    I have installed all available updates in MCUXpresso.

    P&E Micro has latest update

    MCUXpresso IDE v11.1.0 [Build 3209] [2019-12-12]

    I bought new debugger and facing issue with MPC5566 so decide to check with other board but it won't work.

    Did i received faulty debugger?


    • Hello Jay,

      Can you confirm for me that you are booting from QSPI? This is SW8 in OFF, OFF, ON, OFF positions with the first position being SW8-1.

    • Can you also confirm for me that when you connect your device to your MultiLink, you are seeing both the blue and yellow LED illuminated?

      • I checked Blue and Yellow led are ON.

        It seems some other issue from PE Micro debugger, after many tries it start work when I power off the board and again power on then it again stop working but after USB cable reconnect and retried for few times it start works.
