I was having some soldering issues with my crystal I assembled the components on another board and tested. It worked.

I assume that you have a SWD interface, since you have managed to program the board? You can use the debug out port on the DK to connect the custom board to the on-board debugger of the DK, then you run debugging from the IDE/debugger application like you would with the DK.

You only need VDD, GND, SWDCLK, and SWDIO to debug the application on the board. In addition you need to connect VTG of the DK to the VDD of the custom board, to make if debug this board, rather than the nRF5 chip on the DK.

No, i haven't tried to debug how do i debug on Adafruit feather board. I have previously done debugging on NRF52 Dk but for this one i tried to debug on the adafruit feather dk it works fine.

Have you tried debugging the application, to see if there are any errors or HardFaults, etc?

Yes I do have 32.768 kHz LF crystal on my board

Hi,

Do you have the 32.768 kHz LF crystal on your custom board? If not, you may have to configure the application to use the internal RC oscillator.

Best regards,
