**Qualcomm® Hexagon™ DSP 工具链** 编译环境的 Hexagon 8.4.07 工具链。 - **QXDM Professional™ 工具** QXDM Professional 为诊断客户端。 - QSH 框架可以直接调用宏和 API 来发送调试信息以打印字符串和日志数据包。 - QXDM 日志主要用于 aDSP 端调试。有关更多信息，请参阅 [Qualcomm Linux Sensors Guide - Addendum](https://docs.qualcomm.com/bundle/resource/topics/80-70020-7A/overview.html) 中的 [Troubleshoot sensors](https://docs.qualcomm.com/bundle/resource/topics/80-70020-7A/debugging.html)。 Note [Qualcomm Linux Sensors Guide - Addendum](https://docs.qualcomm.com/bundle/resource/topics/80-70020-7A/overview.html) 仅可由许可用户访问。 - QXDM Professional 需要 USB 连接。应用处理器可直接连接到 USB 端口，而 aDSP 却不具备这样的连接能力。 ## 验证 用户可以使用可用于验证这些功能的工具来确定配置的 QSH 功能是否正常运行，或者是否需要注意任何差异。用户可以使用测试工具或 QXDM Professional 检查配置的设置并采取必要的操作。 **使用测试工具显示传感器属性** `ssc_sensor_info` 测试工具会验证 QSH 的功能，并列出所支持的传感器及其各项功能。 ssc_sensor_info Copy to clipboard 以下 shell 输出列出了所有支持的传感器及其属性：

有关单个传感器电平验证的更多信息，请参阅[工具](https://docs.qualcomm.com/doc/80-70020-7SC/topic/test_troubleshoot.html#test-tools)。 ## 在平台上测试传感器 要使用传感器测试应用程序，请参阅[在 Dragonwing RB3 Gen 2 开发套件上测试传感器](https://docs.qualcomm.com/doc/80-70020-7SC/topic/platform.html#test-sensors)。 ## 排除传感器故障 以下资源描述了一些常见问题以及可用于分析和解决这些问题的技术。 Note `` 应被视为设备上的现有路径之一：`/etc/sensors/registry/registry/` 或 `/var/cache/sensors/registry/registry/`。 ### `ssc_sensor_info` 工具无法列出传感器 此错误表示解析传感器注册表失败，导致传感器无法使用 `ssc_sensor_info` 工具列出。执行以下操作来解决此错误： > > > Note > > >
