在 Texas Resuments CC3220SF-LAUNCHXL 上下载、构建、刷写并运行 FreeRTOS OTA 演示
下载 FreeRTOS 和 OTA 演示代码
-
浏览至 Amazon IoT 控制台，从导航窗格中选择 Software (软件)。
-
UNDERFreeRTOS 设备软件，选择配置下载.
-
从软件配置列表中，选择连接到Amazon IoT-TI. 选择配置名称，而不是 Download (下载) 链接。
-
在 Libraries (库) 下，选择 Add another library (添加另一个库)，然后选择 OTA Updates (OTA 更新)。
-
在 Demo projects (演示项目) 下，选择 OTA Update (OTA 更新)。
-
在 Name required (需要名称) 下，输入
Connect-to-IoT-OTA-TI，然后选择 Create and download (创建和下载)。
将包含 FreeRTOS 和 OTA 演示代码的 zip 文件保存到计算机上。
构建演示应用程序
-
将 .zip 文件解压缩。
-
按照 入门中的说明进行操作，将
aws_demos项目导入 Code Composer Studio，为主板配置 Amazon IoT 终端节点、Wi-Fi SSID 和密码，以及私有密钥和证书。 -
打开
freertos/vendors/vendor/boards/board/aws_demos/config_files/aws_demo_config.h#define CONFIG_CORE_MQTT_MUTUAL_AUTH_DEMO_ENABLED定义，并定义CONFIG_OTA_MQTT_UPDATE_DEMO_ENABLED要么CONFIG_OTA_HTTP_UPDATE_DEMO_ENABLED. -
构建解决方案，并确保其构建没有错误。
-
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
-
-
在主板上运行项目，确认它可以连接到 Wi-Fi 和 Amazon 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：
