You need to look into build logs and build directory for the kernel
recipe to see what modules are being built and packaged.
Rightio. (I found that the failure is logged in the "do_rootfs" recipe, but concentrating on the kernel recipe):
I found a problem, straight away: The kernel recipe includes in its SRC_URI a file that (looks like) it sets kernel configuration to load the iwlwifi modules.
However when I build it and boot it and examine /proc/config.gz none of the configuration from the kernel recipe are there
Grepping around for the configuration options I found this file in my build section: build/tmp/work-shared/apalis-imx8/kernel-source/.kernel-meta/cfg/merge_config_build.log
It is not updated on each build, but has been updated today, so I am unsure on when and how it was created.
It says (in part)
