Hi
please check
1. device/nxp/imx8q/mek_8q/SharedBoardConfig.mk
please make sure all the modules you added are listed in this file
divides the storage locations of the kernel modules into two parts : one is inside the ramdisk. and the other is in the vendor_dlkm partition.
You can check the directories $OUT/vendor_ramdisk/lib/modules/ and $OUT/vendor_dlkm/lib/modules/ to see if the files you need are there.
Regards
Daniel
