Can't connect to custom nrf52 board with J-LINK

navarrocantero

We come from here : 

https://devzone.nordicsemi.com/f/nordic-q-a/35180/error-with-nrf52dk-and-mac-os-hs

Now, i have a new development kit and i can program it but now i have a problem with the J-LINK connection, i cant connect with my nordic 58323 custom board 

I have tried from j-link, and j-link commander, and nrfjprog --recover, nothing works :( 

I have tried with a few usb wires too, and a few laptops with differents environments (windows, mac)

Here is the  nrfjprog --recover log :

nrfjprog --recover --log

    Hi,

     

    Are you using P19 (2x5 pin header, top left corner) or P20 (1x8 pin header, just above the SEGGER IC)?

    If using P20, please follow this schematic: https://devzone.nordicsemi.com/f/nordic-q-a/14058/external-programming-using-nrf52-dk/53757#53757

    If using P19 (DEBUG OUT), then connect the 10 pin SWD cable, as well as VDD and GND, to your custom board.

     

    Best regards,

    Håkon

    Hello, thanks for your reply !! 

    My custom board is powered with external supply and, i have tested it that i have +3v between VDD and GND

    I have connected the custom board with the following configuration on port 20:

    nRF52-DK            Custom Board


VDD ------+-------------> VDD
         /
VTG ----+

GND ------------+-------> GND
               /
GND DETECT ---+

SWD IO -----------------> SWD IO

SWD CLK ----------------> SWD CLK


    With same behavior, I cant program it.

    I also tried: 

    nRF52-DK            Custom Board


VDD ------+-------------> VDD
         /
VTG ----+

GND DETECT -----+-------> GND
              
SWD IO -----------------> SWD IO

SWD CLK ----------------> SWD CLK

    And nothing, here is the nrfjprog --recover --log:
