# Download, build, flash, and run the FreeRTOS OTA demo on the Texas Instruments CC3220SF-LAUNCHXL **Important** This is an archived version of the FreeRTOS User Guide for use with FreeRTOS release 202012.00. For the latest version of this document, see the [FreeRTOS User Guide](../../../latest/userguide/index.html). **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 [Getting Started with FreeRTOS](freertos-getting-started.md) to import the `aws_demos` project into Code Composer Studio, configure your Amazon 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_MQTT_DEMO_ENABLED`, and define `CONFIG_OTA_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 Amazon IoT MQTT message broker. When run, the terminal emulator should display text like the following: ``` 0 0 [Tmr Svc] Starting Wi-Fi Module ... 1 0 [Tmr Svc] Simple Link task created Device came up in Station mode 2 142 [Tmr Svc] Wi-Fi module initialized. 3 142 [Tmr Svc] Starting key provisioning... 4 142 [Tmr Svc] Write root certificate... 5 243 [Tmr Svc] Write device private key... 6 340 [Tmr Svc] Write device certificate... 7 433 [Tmr Svc] Key provisioning done...
