** How to estimate runtime performance on dsp**

---

=> adb push snpe-net-run to path /data/local/tmp/test_demo/

=> cd /data/local/tmp/test_demo

=> chmod 777 snpe-net-run

=> settimg library path: export LD_LIBRARY_PATH=./${LD_LIBRARY_PATH} export ADSP_LIBRARY_PTAH=./:${ADSP_LIBRATY_PATH}

=> Then, need to do next step, Let's to show follow cmd: snpe-net-run --container *.dlc --input_list list.txt --use_dsp

=> if running is successful, we can have one output folder.

=> adb pull output folder to your local snpe develop path. follow cmd: snpe-diagview --input_log SNPEDiag.log --output LOGCSVFile > Log 2>&1
(Note: find file SNPEDiag.log from output folder)

On soc SA8155P, with problem about segmentation fault. Solution: copy library “libc++_shared” to "/system/lib"

android-ndk-r21d with problem about lirary "libc++.so" and some undefined reference. Solution: delete library "libc++.so" from "./lib/snpe/armv7a-android"
