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 :

    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:

    Hi,

     

    Could you check the current of your external board, by connecting an am-meter in series with the VDD taken from the nRF5x-DK?

    Also, could you check that the "nRF current measurement" header, next to the USB header, is shorted (if you have cut the SB9 solder bridge)?

     

    Have you tried using Jlink Commander to see what the output is there?

     

    Kind regards,

    Håkon

    Thanks again Håkon.

    I have measured the current consumption between the  VDD jumpered with VTG from my nRF52-DK and my custom board. 

    In idle was 29µA and when i tried the nrjprog --recover  oscilates between 33µA and 130µA.

    The nrf current measurement dosn't have any cut, Its a new development board with factory settings. 

     

    I have tried the jlink commander  too and here is the log : 




    regards!

    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
