Programming external board with nRF9160 DK

[Mr.Newlove]

So this is my understanding of the programming process of an external board using the DK.

Pins from table 1 here: https://infocenter.nordicsemi.com/index.jsp?topic=%2Fug_nrf91_dk%2FUG%2Fnrf91_DK%2Fext_programming_support.html

And this is about as far as I have made it: https://i.imgur.com/EgJqTJN.jpg

So right now I am mostly not knowing where I should put SELECT and SWO lines

Thoughts?

Thanks.

Edit 1: After further reading yes VTG should be used as the select pin. So its optional if you want to power using the DK. Still have no idea where SWO should goto on the external board/chip.

You need to connect: SWDCLK, SWDIO, ground and VDD_nRF

Where did you find that? I was looking everywhere I thought.

And we do not need the reset pin?

I made the drawing, based on a similar drawing posted on DevZone for nRF52 series.

The reset pin is nice to have, but not a must, see reset in the PS.
