I am not able to Flash my custom board although i am able to establish Connection with my custom board using JLink commander. It always Shows an error as shown in JinkErr Image. Also Keil and Nrfgostudio dont work. NrfjProg is intalled but functions like "nrfjprog -f NRF52 --recover " Show error as unknown. Please guide what else can i Diagnose to find the failure. I have attached all screenshots whch i used while flashing the ble_app_uart Software into my Custom Board. I am using the Nrf52DK as my Programmer module and connecting Custom Board as shown in Design.jpg. Please guide as i am not able to Flash any Code into the nrf52 chip.

    According to the user guide you may be able to short shield detect on P5 to ground to activate the port you are already wired up to. See page 18 of the user guide.

    I've been using P20 to program the other boards (BC832 module and some other cheap breakout boards) fine.

    Your wiring diagram above more or less summarizes whatever I know about loading the N52 in a custom board :( Are you sure your custom board powers up fine? Can you ask your h/w buddies to check the custom board for you?
