wifi not recognized about armbuild

[pciavald]

I've made diffs of the /boot and /lib/firmware and a diff of the kernel compilation config between the CentOS build with working wifi (left/origin) and the Fedora build (right/target).

"deleted" thus means that the file is in CentOS rpi4 but not in ansible-built Fedora, "added" means it's in Fedora but not in CentOS.

I hope these can help finding what's missing from the raspberry OS / fedora image, compared to the working Centos build custom made by the Centos engineer from the rpi4 thread.

I then tried to get the firmware files from raspberry, no luck, finally tried rpi-update, still no luck with kernel 5.4.83-v8+.

$ sudo dnf -y install git
$ git clone https://github.com/RPi-Distro/firmware-nonfree.git
$ sudo mv /lib/firmware/brcm{,.org}
$ sudo cp -R firmware-nonfree/brcm /lib/firmware/brcm
$ sudo reboot

$ nmcli

        wifi (brcmfmac), 4E:43:9D:4D:22:9E, hw, mtu 1500

$ sudo curl -L --output /usr/bin/rpi-update https://raw.githubusercontent.com/Hexxeh/rpi-update/master/rpi-update
$ sudo chmod +x /usr/bin/rpi-update
$ sudo rpi-update
$ sudo reboot

$ uname -r

I won’t be able to run a test setup for a week or so. What do you get from nmcli r wifi show And from lsmod ?

After encountering a little issue with the lvm setup of the playbook (#10 <#10>) it went well and I was able to boot the resulting image. However I've used the latest links for Fedora 33 and RaspberryOS, and after booting, updating fedora (excluding kernel* linux-firmware*) and installing the workstation group to get GNOME, the wifi/bluetooth is not working. In my understanding, the playbook installs all RaspberryOS drivers to the Fedora image, so they should have been installed (wifi with plain RaspberryOS works). I did not notice other upgrade packages besides kernel and firmware that could modify the custom files, am I missing something ?

Thanks for that, see if you can interrogate nmcli further for access the wifi nic. I’ve seen the gnome GUI tools get weird in the past, all while the command line bits can see the wifi just fine. I suggest isolating the issue to the lowest level system that should be able to see it. I haven’t been using the wifi on rpi4/f32 and have been myself relying on the wired NICs for my needs - maybe there’s an issue there. Will look once I’ve set up an F33 environment.

Thanks. As I see you're answering from emails, note that I've edited my initial issue and comment with much more detail during the day. I do not think the wifi was operational in your initial build, and i have some clues to check in the diffs between a centos 8 with working wifi and the fedora build. My kernel and hardware skills are not up to the task here ^^

[pciavald]

After a chat on IRC with the creator of the centos image that has wifi, he advised that the only difference should be the version of linux-firmware, and on his image

$ rpm -q linux-firmware
linux-firmware-20200619-99.git3890db36.el8.noarch

He also pointed out to this repo for the kernel: https://git.centos.org/rpms/raspberrypi2/commits/c7-sig-altarch-lts-5-4

He said his build process for the centos 8 rpi4 image was to:

• install appliance_tools from EPEL
• clone the repository to access this folder
• build using the configuration file found in /root/anaconda-ks.conf:
