I'm trying to follow the guide on how to setup a border router with the nRF52840 dongle (see https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/ug_thread_tools.html#configuring-a-radio-co-processor). The guide tells me to build the "nrf/samples/openthread/coprocessor/" app, however when using the VSCode Extension to create the project (see screenshot below), I get the following error:
I've also tried the freestanding option, but when executing the command
west build -p always -b nrf52840dongle_nrf52840 nrf/samples/openthread/coprocessor/ -- -DOVERLAY_CONFIG="overlay-usb.conf" -DDTC_OVERLAY_FILE="usb.overlay"
I only get the error
usage: west [-h] [-z ZEPHYR_BASE] [-v] [-V] <command> ...
west: error: argument <command>: invalid choice: 'build' (choose from 'init', 'update', 'list', 'manifest', 'diff', 'status', 'forall', 'help', 'config', 'topdir', 'selfupdate')
