Forums - fail to run Hexagon SDK example on Pixel 2

I am trying to running examples of Hexagon DSP SDK on my Pixel 2.

The example is "3.3.3/examples/compute/conv3x3a32_v60" , and I get logs like below.

wzh@cmpl-alios[1]conv3x3a32_v60 $ adb shell
walleye:/ # LD_LIBRARY_PATH=/system/lib:/vendor/lib ADSP_LIBRARY_PATH='/system/lib/rfsa/adsp:/vendor/lib/rfsa/adsp:/dsp;' /vendor/bin/conv3x3a32_v60
Usage: conv3x3a32_v60 <width (must be multiple of 128)> <height> <number of frames> <uSec per frame> <DSP MIPS vote> <BUS MBPS vote> <verbose (0/1)>

error: -1
calling dspCV_deinitQ6()...
return value from dspCV_deinitQ6(): -1
- failure

I look into this error, and found that the root failure is `remote_handle_open("dspCV)"` which should be implementated by `libadsprpc.so`. As this is close sourced, I still checked Android log and found that adsprpc seems trying to open `oemconfig.so` but run into failure.

• fastrpc_apps_user.c:639: Error fffffffb: remote handle open domain failed. domain 0, name dspCV, dlerror cannot open oemconfig.so

• fastrpc_apps_user.c:639: Error fffffffb: remote handle open domain failed. domain 0, name dspCV, dlerror signature verify start failed for libdspCV_skel.so

I navigated the image of Pixel 2, fail to find the `oemconfig.so`.

So, the question is, is this failure is expected on Pixel 2 (i once read that DSP is disabled from user on Pixel2)?

If this is not expected, how can i get the `oemconfig.so` correctly setupped?

Thank you very much!
