Install the initial version of firmware on the Nordic nRF52840 DK - FreeRTOS

Install the initial version of firmware on the Nordic nRF52840 DK

Important

This reference integration is hosted on the Amazon-FreeRTOS repository which is deprecated. We recommend that you start here when you create a new project. If you already have an existing FreeRTOS project based on the now deprecated Amazon-FreeRTOS repository, see the Amazon-FreeRTOS Github Repository Migration Guide.

This guide is written with the assumption that you have already performed the steps in Getting started with the Nordic nRF52840-DK and Over-the-Air Update Prerequisites. Before you attempt an OTA update, you might want to run the MQTT demo project described in Getting Started with FreeRTOS to ensure that your board and toolchain are set up correctly.

To flash an initial factory image to the board

  1. Open freertos/vendors/nordic/boards/nrf52840-dk/aws_demos/config_files/aws_demo_config.h.

  2. Replace #define CONFIG_CORE_MQTT_MUTUAL_AUTH_DEMO_ENABLED with CONFIG_OTA_MQTT_UPDATE_DEMO_ENABLED or CONFIG_OTA_HTTP_UPDATE_DEMO_ENABLED.

  3. With the OTA Update demo selected, follow the same steps outlined in Getting started with the Nordic nRF52840-DK to build and flash the image.

    You should see output similar to the following.
