Hello,

Thank you for response. I knew about connection to P20 already.

But my problem is different. A problem exactly as described in https://devzone.nordicsemi.com/f/nordic-q-a/90665/nrf-52840dk-debug-out-on-board-version-3-0-0-not-working#:~:text=nRF%2052840DK%20debug%20out%20on%20board%20version%203.0.0%20not%20working.

Basically my board nRF58240-Dk (PCA10056, 3.0.0, 2022.36)does not support P20 for configuration an external nRF52840 according to schematics of this DK board.

I will try to use a P19 instead.

Please close a case.

Sincerely,

Take a look at the connections described here for P20 that needs to be connected to your custom board. For simplicity attaching the snapshot here

Hello, Attached snapshoot of the "My nRF52840 DK board's P20". Please see diagram for programming in the document RE: Programming a custom board with an NRF52840 dev kit.

The P20 pins label on my DK board different then in thread.

Could you please provide what P20 pins on my board (attached) correspondent to signals on RE: Programming a custom board with an NRF52840 dev kit diagram:

GND_DETECT, SWD_CLK, SW_IO, VTG, VDD_NRF, VDD_NRF.

Hello,

I am trying to use the connection diagram from the "Programming a custom board with an NRF52840 dev kit" thread. Snapshoot attached.

Attached snapshoot of the "My nRF52840 DK board's P20".

Attached snapshoot from the P20 "P20 from nRF52840 DK v1.0.0 User Guide".

Here are difference of the pin labels between "My nRF52840 D board's P20" and "P20 from nRF52840 DK v1.0.0 User Guide".

Basically, could you please provide a pin labels on my DK "My nRF52840 DK board's P20" which (pin labels) correspondent to "Programming a custom board with an NRF52840 dev kit" thread diagram.

I tried the Nordic support suggestions regarding programming and debugging nRF52840 based custom boards. But no succes.

Can you please describe exactly what you tried and links to other Nordic support suggestions?

The documentation for how to use nRF52840 DK is clearly mentioned here
