我有一个 Raspberry Pi 3 A+，并且我将 Raspberry Pi OS 32 位下载到我的硬件上。我已按照以下说明安装了 IoT Edge:Create and provision an IoT Edge device on Linux using symmetric keys.连接到 IoT 中心并运行 IoT 代理和 IoT 边缘模块工作正常。当我尝试推送额外的模块时，问题就出现了。
我尝试遵循这些Tutorial: Develop IoT Edge modules with Linux containers部署 IoT Edge 模块。当我将其部署到虚拟机(Linux ubuntu 20.04 x64)时，它工作正常。但当我尝试对我的 Raspberry 进行相同的部署时，它不起作用。
如果您不熟悉说明；这是在 VS Code 中创建*Azure IoT Edge:新 IoT Edge 解决方案时创建的模板代码。我唯一添加的基本上就是名称“temperatureTest”。其余的代码是为我生成的。正如我所提到的，它适用于 (Linux ubuntu 20.04 x64) VM。但当我把它推到我的树莓派上时它不起作用。 (在部署我的配置文件之前，我确实将“设置边缘解决方案的默认目标平台”交换为arm32v7)。

任何帮助将不胜感激。
最佳答案
因此，我们需要调查一些事情，因为我们无法离线解决整个问题..
首先，我们必须确保更新我们的物联网设备固件!
更新 Raspberry Pi 的固件:sudo rpi-update
尝试部署开箱即用的 TemperatureSensor模块provided by Microsoft ，这可能是您的 RaspberryPI 上的一些配置问题，此示例模块部署将确保模块代码和连接问题中没有错误。
检查 operating system 的版本:
cat /etc/os-release检查.NET Core版本:dotnet --version检查Docker版本:docker --versionPing 网站以验证互联网连接:
ping www.google.com使用traceroute诊断网络问题:traceroute www.google.com这将有助于验证连接。检查 Azure IoT Edge runtime logs :
sudo iotedge logs检查特定模块的日志:sudo iotedge logs <module-name>始终执行此操作以获取初始日志以进行故障排除!这是我最喜欢的一步! 检查所有模块的状态:
sudo iotedge list检查特定模块的状态:sudo iotedge list <module-name>重新启动 Azure IoT Edge 运行时:
sudo systemctl restart iotedge重启特定模块:sudo iotedge restart <module-name>
** 在某些情况下，我发现使用正确的镜像重新镜像 Raspberry pi 可能有助于解决许多隐藏的问题，并且无法通过常规故障排除步骤和文档进行追踪。
