Good Day!

My name is Jason Oh from Korea(South).

 

I have ported android 7.1.2 successfully to our custom  i.mx6q board.

CPU       : i.MX6Q

OS         : Android 7.1.2 Nougat (N7.1.2_2.0.0, 4.9 kernel)

CODEC : WM8960

 

When I record microphone, it has recorded normally around 5 seconds, then errors occur.

Could someone help me to fix this problem?

If you need more infomation (schematic, source code, etc..), please tell me!

 

Thank You!!
