在Snapdragon 820（Ubuntu 16.04）上运行用于Hexagon DSP的高通fastRPC计算器示例时出错

我正在尝试从OpenQ820开发工具包（Snapdragon）上的Hexagon SDK运行基本计算器示例，但在尝试运行calculator_walkthrough.py python脚本来运行示例时，该过程失败

我正在Ubuntu 16.04.2上运行Hexagon SDK 3.0。Android NDK安装在正确的位置（根据Hexagon SDK文档）

该示例似乎一直正确运行到以下几点：

---- root/remount device ----
* daemon not running. starting it now on port 5037 *

restarting adbd as root
remount succeeded

我已卸载并重新安装Hexagon SDK，尝试在设备处于安全模式和正常模式时运行脚本，检查所有必需的库是否位于正确的目录中，但无法找到问题的解决方案

谢谢

/data/getserial已作为目录存在于您的设备上。请将其删除，然后重试。

我似乎无法在我的设备上找到/data/get serial。我已使用以下命令搜索了它'kaz@kaz：~$find/home/kaz-名称“getserial”，但找不到与上面路径类似的内容。我也试过用三台不同的笔记本电脑，同样的错误也出现了。我还可以使用两块Snapdragon 820电路板，另一块工作得非常好，所以我倾向于认为问题在于电路板本身。谢谢您的帮助。您是否尝试过“adb shell ls-la/data”并查找“getserial”？
