Board files

The board definitions of the Icarus SoM Development Kit are currently not included in the GitHub repository of Zephyr OS. In the mean time, the board files for the DK are available on this page:

nRF Connect SDK Version	Board Files Update Pack (BFUP)
2.1.x	BFUP-v1.2.1-nrf-2.1.x
2.2.x	BFUP-v1.2.1-nrf-2.2.x

Please extract the archive into the zephyr/boards/ directory of your SDK version. This is usually ~/ncs/<sdk-version>/zephyr/boards/.
