What i missed in my build process ?
Dear @O. JUD, It seems like you have missed adding the wm8960 audio driver package. Please add them to your build and try again.
Hi
For me the device driver is build in the kernel not as the module furthermore i cannot find any package called *wm8960* in my build folder. Are you sure it is provided as a module ? . Can you share the exact name of the package?
This is my image build recipe, i keep the same contents as imx-image-multimedia.

Dear @O. JUD, Here is the link for building the Yocto image for our I-Pi SMARC IMX8M Plus product, it has all the packages and drivers you need.
https://www.ipi.wiki/pages/imx8mp-docs?page=HowToBuildYocto.html
@Kothandaraman Kannadasan , I followed the steps discribed in the link your provide .
Except that i used the Hardknott branch with the command :
repo init -u https://github.com/ADLINK/adlink-manifest -b lec-imx-yocto-hardknott -m adlink-lec-imx8mp-yocto-hardknott_1v2.xml
as i need kernel 5.10 to build an external Lon network driver wich support only this version of the kernel.
When I build i used "bitbake imx-image-multimedia" .
So , i created my own meta-fnd with a recipe image with the same contents from sources/meta-imx/meta-sdk/recipes-fsl/imx-image-multimedia.bb . I only added my own packagegroup-fnd-apps as you can see in my previous post. So the build would be the same if i'am correct.
So now i use bitbake my-image-name
Dear @O. JUD, Please use the following command while building the image.
repo init -u https://github.com/ADLINK/adlink-manifest -b lec-imx-yocto-hardknott -m adlink-lec-imx8mp-yocto-hardknott_1v5.xml
Dear @Kothandaraman Kannadasan , yes I tried the Image and dtb of core-image-minimal from this branch and it works.
I will rebuild my image from adlink-lec-imx8mp-yocto-hardknott_1v5.xml
thanks
@Kothandaraman Kannadasan
yes I tried the Image and dtb files of core-image-minimal from this branch and it works.
