Hello Novello,

What version of NCS are you currently working on? The nRF52840 on thenRF9160 DK functions as a board controller, and as stated under the board controller chapter:

If you want to route some pins differently from what is done in the preprogrammed firmware, program the Hello World sample instead of the preprogrammed firmware. Build the sample (located under ncs/zephyr/samples/hello_world) for the nrf9160dk_nrf52840 board. To change the routing options, enable or disable the corresponding devicetree nodes for that board as needed. See Board controller firmware for detailed information.

The nRF52840 controls analog switches on the nRF9160 DK, enabling routing of some of the nRF9160 GPIO pins to onboard functionality, for example LEDs, or the regular GPIO interfaces. More information in the nRF9160 DK User Guide. Make sure to route the correct UART pins in regards to the VCOM ports. The board documentation found in the Zephyr repo provides more information on the board controller FW

[quote user=""]The other question is Wich is the best mainline to use with which version of zephyr.[/quote]

We recommend using the latest tag (currently v1.5.1) of nRF Connect SDK, which is the official SDK to use with nRF9160 DK.

Kind regards,
Øyvind
