我正在尝试在Open-Q 820开发套件(Snapdragon)上运行Hexagon SDK中的基本计算器示例，但是当尝试运行calculator_walkthrough.pypython脚本来运行示例时，该过程失败了。
我在 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)。
该示例似乎可以正常运行，直到以下一点：
---- root/remount device ----
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
restarting adbd as root
remount succeeded
failed to copy '/home/kaz/Qualcomm/Hexagon_SDK/3.0/tools/elfsigner/getserial' to '/data//getserial': Is a directory

设备肯定已连接，可以使用以下命令查看：
kaz@kaz:~/Qualcomm/Hexagon_SDK/3.0/examples/common/calculator$ adb devices
List of devices attached

我已经卸载并重新安装了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，但找不到问题的解决方案。
谢谢
/data/getserial 已经作为目录存在于您的设备上。 将其删除，然后重试。
