如何使模块之间的Iot Edge消息路由在arm32（Raspberry Pi）上工作

时间：2018-12-20 09:55:28

标签： raspberry-pi azure-iot-edge

我使用 C＃模块模块模板，通过视图->命令面板...-> AzureIotEdge：NewIoTEdgeSolution 使用Visual Studio Code创建了一个Iot Edge解决方案。这将生成具有两个模块的Iot Edge解决方案： tempSensor 创建带有虚拟遥测数据的消息，而 SampleModule 应该会接收这些消息，进行打印，然后将其传递给IotHub

我为 arm32 构建解决方案，并将其部署到Rasperry Pi（运行最新的Raspbian）。然后，这些模块显示为正在设备上运行，但是如果我监视d2c消息，则IoT中心中没有到达。

如果我在设备上运行 sudo iotedge日志tempSensor -f ，则可以看到正在生成消息。

如果运行 sudo iotedge日志SampleModule -f ，我只会看到 IoT Hub模块客户端已初始化。记录在Init（）方法中。 PipeMessage方法没有日志记录，似乎根本无法访问。

如果我为amd64构建解决方案并将其部署到虚拟机，那么一切都会按预期工作。

有没有办法让它在运行Raspian的Raspberry Pi上运行？

顺便说一句：我也尝试了 Azure Functions C＃模块模板。结果相同：在amd64上它可以工作，但在arm32上却不能。

因此，此问题是由System.OutOfMemoryExceptions引起的。但是导致这些异常的原因是什么？

Update2 ：这似乎是一个已知问题（请参见here），可以通过将 OptimizeForPerformance 设置为 false 来解决。 。我会尝试一下，看看是否可行。

2 个答案:

答案 0 :(得分：1)

似乎与以下问题有关 https://docs.microsoft.com/en-us/azure/iot-edge/troubleshoot#stability-issues-on-resource-constrained-devices

请参考链接并关闭部署清单中的OptimizeForPerformance。

答案 1 :(得分：1)

由于edgeHub模块中的System.OutOfMemoryExceptions，模块之间的消息路由不起作用。 here对问题进行了描述和讨论。

Microsoft已实现here中描述的解决方案。

简而言之：如果在Raspberry Pi上运行IotEdge解决方案，则必须将环境变量 OptimizeForPerformance 设置为 false 。
