Hi,

It looks like you might have missed some steps in the installation procedure. Are you able to compile any other nRF Connect SDK samples through with either command line or through the Visual Studio Code extension?

Could you retrace the installation steps either through https://academy.nordicsemi.com/topic/exercise-1-1/ or https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/getting_started/assistant.html and make sure that nrfutil and nrf command line tools are properly installed

Kind regards,
Andreas

Hi,

I just updated SDK to v2.4.0 and I have the same problem with our custom nrf9160 board. Flashing works on SDK 2.3.0 without any issues.

Flashing nrf9160dk seems to work.

Edit:

I updated our board.cmake using ncs/v2.4.0/zephyr/boards/arm/nrf9160dk_nrf9160/board.cmake and flashing started to work.

Thanks for your great support! I can flash successfully after modifying board.cmake as follows.

board_runner_args(nrfjprog "--softreset")
board_runner_args(jlink "--device=nRF52832_xxAA" "--speed=4000")
include(${ZEPHYR_BASE}/boards/common/nrfjprog.board.cmake)
