Issue programming my board with the nrf9160

galook

Hello,

I have designed this schematic according to reference designs provided by Nordic Semi, however I might have failed as I am unable to flash the main module. I should mention I am a beginner, however not a complete beginner, as I've created functioning PCBs in the past.

I am flashing it using the nrf9161DK via SWD and I am sure the connections are correct. Still, the Programmer app of Nordic SDK doesnt recognize the new board with the nrf9160

The following is the log file of "nrfjprog --eraseall --log" with the DK connected by USB to the host computer and my board connected to the DK by the P20 pins
