RPI WiFi not loading module

Hi

I have problem to get my WiFi working on boot on Raspberry Pi 3.

The problem is that wlan0 interface not showing up, if I manually
run modprobe brcmfmac it works.

To try to "force" the load of brcmfmac i added it to KERNEL_MODULE_AUTOLOAD and
that generated an file in /etc/modules-load.d/ -> brcmfmac.conf but it is
still not loaded.

I use systemd an to my understanding systemd-modules-load.service is
handling module auto load, but that file is missing and I cant see how to
include it in my build.

Building thud version and I have added the following to my image recipe:

DISTRO_FEATURES_append = " wifi"

IMAGE_INSTALL_append = " iw wpa-supplicant packagegroup-base
module-init-tools"

IMAGE_INSTALL_append = "\
    linux-firmware-rpidistro-bcm43430 \
    linux-firmware-rpidistro-bcm43455 \
    bluez-firmware-rpidistro-bcm43430a1-hcd \
    bluez-firmware-rpidistro-bcm4345c0-hcd \
 "
Then i have symlinked wpa-supplicant service to load wpa-supplicant.conf
file and that work when I manually loads the module.

Best regards
Jonas

for rpi issues I would suggest to open ticket on meta-raspberrypi
github with stated which yocto branch and other details. Thanks.

Hi,

Thanks for the reply.

I have looked in to some of the issues on meta-raspberrypi and found some
good information but nothing to fix my issue, i will post an
issue there as well for the rpi specific problem.

The question i have regarding Yocto is about KERNEL_MODULE_AUTOLOAD, i get
the module added to /etc/modules-load.d/ but cant
understand what service/script that is responsible for loading it.
