MQS on i.MX6ULL with Linux kernel linux-fslc 4.9.x

[sarelbreet]

MQS on i.MX6ULL with Linux kernel linux-fslc 4.9.x

I am trying to get the MQS working on an i.MX6ULL with Linux kernel based on linux-fslc 4.9.x.

Upon kernel start I get an error:

imx-mqs sound-mqs: ASoC: CODEC DAI fsl-mqs-dai not registered

imx-mqs sound-mqs: snd_soc_register_card failed (-517)

My kernel debug log is shown below.

Do you maybe have an idea what could be wrong?

Thanks in advance for your help.

Kind regards,

Sarel

It seems that you are having some issues in your DTS,  you can check an example :

mqs example can be found in imx6ul-14x14-ddr3-arm2-mqs.dts

Thanks for the help. I found that I was missing the CODEC source file sound/soc/codecs/fsl_mqs.c. After adding this, the CODEC is now registered successfully, but when trying to play a sound (simply using speaker-test) it fails as shown below: Thanks for any help. Please note I am a Linux beginner :smileywink:
