在Snapdragon 820（Ubuntu 16.04）上運行Qualcomm fastRPC計算器Hexagon DSP的示例

Question

我試圖運行Open-Q 820開發工具包（Snapdragon）上的Hexagon SDK的基本計算器示例，但試圖運行calculator_walkthrough.py python腳本運行失敗的例子。

我在Ubuntu 16.04.2上運行Hexagon SDK 3.0。 Android NDK安裝在正確的位置（根據Hexagon SDK文檔）。

的例子似乎正確運行，直到以下點：

---- 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 ---- 
adbd is already running as root 
remount succeeded 
---- Push Android components ---- 
329 KB/s (32104 bytes in 0.095s) 
168 KB/s (12940 bytes in 0.075s) 
---- Push Hexagon Components ---- 
256 KB/s (17992 bytes in 0.068s) 
---- 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 

該裝置肯定連接，並且可以使用下面的命令可以看出：

kaz@kaz:~/Qualcomm/Hexagon_SDK/3.0/examples/common/calculator$ adb devices 
List of devices attached 
252020106151601286 device 

我已經卸載和重新安裝Hexagon SDK嘗試在設備處於安全模式和正常模式時運行腳本，檢查所有必需的庫位於正確的目錄中，但找不到問題的解決方案。

謝謝

/data/getserial已經作爲目錄存在於您的設備上。刪除它，然後重試。
