Audio HAL 2.0 not found on iMX8M Nano

Hi,

I am working on iMX8M nano chipset. I have ported android 10 on imx8M nano evk and is working fine. But, when I port same build on a custom hardware, and try to launch the android app from ADB shell using "adb shell monkey --pct-syskeys 0 -s 13 -p com.example.myapplication -v 500".

I get the following prints after which the service restarts at random times. The codec used on my custom board is tas2770. The difference between evk and custom hardware is that the EVK has 4 cores and custom board has a single core.

 

The debug prints that I observe are shown below:

Is this an application related issue or a HAL related issue?

 

Inputs on why the board application/service restarts would be highly appreciated.

 

Also, the last 2 times I posted a question, I can not view my question after 24hrs on the community forum

 

TIA,

Anurag
