在 Snapdragon 820 (Ubuntu 16.04) 上运行 Hexagon DSP 的 Qualcomm fastRPC 计算器示例时出错

Question

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，但是在尝试运行 calculator_walkthrough.py python 脚本来运行示例时该过程失败。

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）。

该示例似乎可以正确运行，直到以下几点：

---- 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
ERROR: testsig:-o is not a valid 32 bit integer
---- root/remount device ----

remount succeeded

---- Run Calculator Example Locally on Android ----

- starting calculator test
adspmsgd not supported
- allocate 4000 bytes from ION heap
- creating sequence of numbers from 0 to 999
- compute sum locally
- sum = 499500
- success

adspmsgd_stop failed
---- Run Calculator Example on aDSP ----

- starting calculator test
adspmsgd not supported
- allocate 4000 bytes from ION heap
- creating sequence of numbers from 0 to 999
- compute sum on the aDSP
Error: compute on aDSP failed

usage: /data/calculator <1/0 run locally> <1/0 logcat> <uint32 size>

adspmsgd_stop failed
Done

设备肯定是连接的，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 
252020106151601286  device

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在正确的目录中，但找不到问题的解决方案。

谢谢

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