Pinebook Pro attempting to load brcm drivers from invalid directory

ARM
1

dmesg shows a bunch of lines like this:

brcmfmac… loading /lib/firmware/6.15.0-1-MANJARO-ARM/brcm/… failed with error -20

6.15.0-1-MANJARO-ARM is not a directory, and as far as I can tell, it should be loading from /lib/firmware/brcm/

I had issue of Wi-Fi not connecting after switching from stable to unstable branch. Someone else on this forum had this issue, and it was apparently solved by adding line to mount boot partition in /etc/fstab and reinstalling kernel.

Edit: this is the post I’m referring to: WiFi no longer works

After adding the recommended line, and reinstalling the kernel with

pacman -Su linux

and rebooting, I no longer had any wlan0 device. After some exploration, I discovered this in dmesg. How to fix?

Apologies for no formatting. I’m posting from my phone, as I have no Internet access from my Pinebook Pro.

I do not have a pinebookpro but I have noticed this on the newer kernels where it is looking for a certain firmware name to load and then falls back and loads another name. It starts out by checking it’s known places where the firmware could be when it is looking for a certain name then settles for some other name. You need to post all of your dmesg to see what is going on. You are just assuming it is just looking in one place.

Additional:

I wonder if this could be your problem:

Wi-Fi takes a minute or two to connect on my Pinebook Pro (unstable branch) since updating to 6.14, if I remember correctly. I’ve neither had to edit /etc/fstab nor reinstall kernels since I first installed GNOME in 2022.

Either way, quite some time ago I had to downgrade wpa_supplicant to 2:2.10-8 and am still using that version.

Here’s relevant bits from my dmesg :
