# Download, build, flash, and run the FreeRTOS OTA demo on the Texas Instruments CC3220SF-LAUNCHXL **Important** This reference integration is hosted on the Amazon-FreeRTOS repository which is deprecated. We recommend that you [start here](freertos-getting-started-modular.md) 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](github-repo-migration.md). **To download FreeRTOS and the OTA demo code** + You can download the source code on the GitHub site at [https://github.com/FreeRTOS/FreeRTOS](https://github.com/FreeRTOS/FreeRTOS). **To build the demo application** 1. Follow the instructions in [Get Started with FreeRTOS](freertos-getting-started.md) to import the `aws_demos` project into Code Composer Studio, configure your AWS IoT endpoint, your Wi-Fi SSID and password, and a private key and certificate for your board. 1. Open `freertos/vendors/vendor/boards/board/aws_demos/config_files/aws_demo_config.h`, comment out `#define CONFIG_CORE_MQTT_MUTUAL_AUTH_DEMO_ENABLED`, and define `CONFIG_OTA_MQTT_UPDATE_DEMO_ENABLED` or `CONFIG_OTA_HTTP_UPDATE_DEMO_ENABLED`. 1. Build the solution and make sure it builds without errors. 1. Start a terminal emulator and use the following settings to connect to your board: + Baud rate: 115200 + Data bits: 8 + Parity: None + Stop bits: 1 1. Run the project on your board to confirm it can connect to Wi-Fi and the AWS IoT MQTT message broker. When run, the terminal emulator should display text like the following: ``` 0 1000 [Tmr Svc] Simple Link task created Device came up in Station mode 1 2534 [Tmr Svc] Write certificate... 2 5486 [Tmr Svc] [ERROR] Failed to destroy object.
