When using this board with RIOT, set the BOARD variable to nrf5340dk-app in your Makefile. If you follow the standard RIOT project structure, your Makefile should look like this:

# name of your application
APPLICATION = hello-world

# Change this to your board if you want to build for a different board
BOARD ?= nrf5340dk-app

# This has to be the absolute path to the RIOT base directory:
RIOTBASE ?= $(CURDIR)/RIOT

include $(RIOTBASE)/Makefile.include

Support for the nRF5340DK-app board

General information

The nRF5340DK is a devboard based on nRF5340 MCU which offers a dual core Cortex-M33 with one application core and one network core. The network core is able to handle Bluetooth 5.3, BLE, mesh, NFC (only tag emulation, no reader support), Thread and Zigbee connectivity. Currently only the application core can be used with RIOT-OS.

The board features four LEDs, four user buttons/switches and a reset button.

Flash the board

The board is flashed using JLink or nrfjprog software. Programs needs to be installed.

The process is automated in the usual make flash target.

Accessing STDIO via UART

The STDIO is directly accessible via the USB port. On a Linux host, it’s generally mapped to /dev/ttyACM0.

Use the term target to connect to the board serial port
