you should read my answer to the other poster more carefully. I pointed them to the arm connector which you'll need to have mounted on your board connected to the SWDIO/SWDCLK/GND/VDD on that nRF52 chip. Then see the reference manual for the nRF52 Dev Kit which you can find under the resources tab at the top of the page here and see how to use Debug OUT with a 10 pin 0.5" pitch FTSH connector and cable.

So no you don't connect the SWD... pins to the same ones on the DK, you connect them to the debugger pins and the debugger drives them.

Thanks a lot for replying and sorry for my hard question.

So if i get it correctly i can program an nrf52 soc that is part of a custom pcb from a different nrf52 development kit.

What connections do i have to make?

Should i connect SWDIO and SWDCLK pins from nrf52 dev board to the same pins of the nrf52 soc, then connect dev board to pc with usb and that's all?

Can you tell me a short step by step process to connect dev board to an external nrf52 and program it?

I am really new to embed systems and i am discovering a whole new universe!

Thanks in advance

You can program your pcb by nrf52 dev board. Just link the 4 programming pins to your pcb.(you need supply extra power to your pcb)

It will skip dev board when it detected your pcb, and it also can enter debug mode with keil C.

Your question is very hard to understand, however I wrote an answer to someone else about programming custom boards yesterday, perhaps that would help you.
