Forums - Crash in libcdsprpc.so

Hello. I'm using Hexagon SDK 3.4.2. I compiled calculator project, and pushed it to devices, generated signature, and it run ok from 'adb shell':

 /vendor/bin/calculator 0 1000                                        

- starting calculator test
- allocate 4000 bytes from ION heap
- creating sequence of numbers from 0 to 999
- compute sum on the DSP
- sum = 499500
- success

Then I compiled the APK, installed it, run, and got next crash:

I tried to run apk provided by Qualcomm the directory calculator_c++_app, and it fails with the same error

I compiled shared object with nextcommand:

make tree V=hexagon_Debug_dynamic_toolv83_v60

I signed the result(libcalculator_skel.so) and pushed to /data/app

my processor is Snapdragon SDM630, with hexagon 642

As I understand, cDSP is not available on my procesor, but library libcdsprpc.so is pointed here, instead of libadsprpc.so
Any help will be really appreciated
