Custom board NRF52832 blinking LED using NRF52-DK P20

[Alanarf]

Hi all, 

I have a custom board with LED on PIN 11 of nRF52832, and I am using SWD P20 configuration to program my board through nrf52 DK PCA10040. 
Apparently, nRFgo Studio find my custom board, so I want to blink the LED on my board using the blinky example. 

But when I upload the code to my board, nothing happens.

Here is the output of SES:

Here, what appear on nRFgo after loading the project: 

And before loading the program was like this:



Do i need to create a custom_board.h? If so, why when I debug the example on SES, in boards.h the pca10040.h is still chosen instead of  custom_board.h?

What am I missing?

Thanks!

Yes, I was aiming at the crystals, but they seem to be okay indeed. Thank you for the update.

Have you configured the blinky example to use P0.11 instead of the LEDs configured in pca10040.h (P0.17-P0.20)? pca10040.h is likely chosen because you're using the chip on the DK which checks the BOARD_PCA10040) define in boards.h and uses the pca10040.h header file instead of your custom_board.h.

Can you show me how your board custom board is connected to the NRF52DK debugger? Please use the picture below as reference when connecting your custom board to a DK's debugger.

Best regards,

Simon
