When I use pre built images from 4.9.88 Ia m not getting the error
Can someone help me why ? whats the difference between 4.9.88 and 4.14.98 , do i need to add any patch or chnages when i use 4.14.98.

Hi Terry
>whats the difference between 4.9.88 and 4.14.98..
one can look at link below, column "Supported Platforms/Demo Images"
In general recommended to use latest linux release.

Hi Igor,
Thank you for the reply, the link says even 4.14.98 also supports Imx8MQ.
I have everything else works for me except the audio, If I change the kernel version to Linux 5.10.52_2.1.0 going to be redoing of my work which I had done so far for my custom board.
can you please provide with information , which could help me to make things work on 4.14.98.
I hope NXP would have tested 4.14.98 images in IMX8MQ , is there any know patches which need to be done for SAI for audio.
Thanks and regards
Terry
