在 Texas Instruments CC3220SF-LAUNCHXL 上下载、构建、刷写并运行 FreeRTOS OTA 演示

重要

该参考集成托管在已弃用的 Amazon-FreeRTOS 存储库中。当您创建新项目时，我们建议从此处开始。如果您已经有一个基于现已弃用的 Amazon-FreeRTOS 存储库的 FreeRTOS 项目，请参阅 亚马逊免费版 RTOS Github 存储库迁移指南。

下载 FreeRTOS 和 OTA 演示代码

• 您可以在 GitHub 网站上下载源代码，网址为 https://github.com/FreeRTOS/FreeRTOS。

构建演示应用程序

1. 按照 开始免费试用 RTOS中的说明进行操作，将 aws_demos 项目导入 Code Composer Studio，为主板配置 AWS IoT 终端节点、Wi-Fi SSID 和密码，以及私有密钥和证书。

2. 打开 freertos/vendors/vendor/boards/board/aws_demos/config_files/aws_demo_config.h，注释掉 #define CONFIG_CORE_MQTT_MUTUAL_AUTH_DEMO_ENABLED 并定义 CONFIG_OTA_MQTT_UPDATE_DEMO_ENABLED 或 CONFIG_OTA_HTTP_UPDATE_DEMO_ENABLED。

3. 构建解决方案，并确保其构建没有错误。

4. 启动终端模拟器，并使用以下设置连接到主板：

   • 波特率：115200

   • 数据位：8

   • 奇偶校验：无

   • 停止位：1

5. 在主板上运行项目，确认它可以连接到 Wi-Fi 和 AWS IoT MQTT 消息代理。

终端模拟器在运行时应当显示类似以下内容的文本：
