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

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

nrfjprog version 9.7.3

can anyone help me ?

  • Hi,

     

    If you measured between VTG and VDD, then you have measured the current going into the Segger IC, and not the current going into your custom board. "VTG" is an input for the SEGGER IC to use this specific port for programming, as the DK has a total of 3 debug outputs (P19, P20, and on-board nRF).

    You should measure the current like this:

    VDD ------+--<AM-METER>-> VDD
             /
    VTG ----+
    
    GND ------------+-------> GND
                   /
    GND DETECT ---+
    
    SWD IO -----------------> SWD IO
    
    SWD CLK ----------------> SWD CLK

     

    You could also check if there's voltage on the VDD (in case you've used the board for current measurement on a previous occasion and cut SB9).

     

    Best regards,

    Håkon
