Custom nRF52840 DK board dual UARTE Zephyr application

Overview

This is an application that demonstrates how to implement a simple board that inherits from the nRF52 series. The board defines two UARTEs that are used in the application.

The custom board can be found in boards\arm\nrf52840dk.

You can flash this application to the nRF52840 DK board.

Getting Started

This application relies on the project and workspace structure described in zephyr-application.

Building and Running

Build the application using the custom nRF52840dk board. Not to be confused with the nrf52840dk_nrf52840 board that is provided already.

west build -b nrf52840dk app

Flash the application.

west flash
