I am using i.mx7D PicoPi board.
Previously I was tried to build AVS in fsl image locally. But now I found a link which is providing the info to build Alexa SDK using yocto: "https://community.nxp.com/docs/DOC-340189 ".
In this image every dependency is added and AVS is working well, but I am unable to add a custom sound card to this kernel image. I added the corresponding driver files and did the configuration in corresponding Makefile and Kconfig file and in device tree file also.
When I am trying to enable my sound card driver from menuconfig, it is not getting effected in the final image. And the when I am checking back the kernel configuration in menuconfig editor, the driver is deselecting.
When I did this in fsl normal image, the sound card is added successfully and I am able to record the voice.
Help me regarding this..
Thanks in advance..
