Flashing custom nRF52840 using nRF52840DK Rev2

Hello, 

I am using the nRF52840DK for development  and I was able to cross flash another nRF52840DK using the debug out/in ports, flashed several 52832 boards, however, for the board that I just finished designing and assembling, I just can't figure out the right pinout.

I am using the Tag-Connect TC2050 footprint on the target PCB and I have the following layout:


And this schematic for the connector

And this is my schematic for the 52840 chip

Do you see anything out of the ordinary with those?

If not, what are the right connections from P20? I want to have the board powered from the Tag-Connect too.

I found this schematic in the fab files but I am not sure how up to date my PCB is for it (REV2)


Many thanks in advance
