No longer need to change brcmfmac43455-sdio.txt. — The preceding unsigned comment was added by YKLA‎ (talkcontribs)

The problem is that there are two different files called brcmfmac43455-sdio.txt I migrated my Pi3 install to the Pi4, so I found out the hard way. The page is showing how to determine if you have the Pi3 or Pi4 version of the file.

Are you suggesting that there is now a single brcmfmac43455-sdio.txt file that works on the Pi3 and the Pi4 ?

Just cp firmware-nonfree/brcm to lib/firmware/brcm is ok. No need change any files.


I think it would be good to add more details for bluetooth as well. I have a well configured (I believe) kernel and all the required tools for bluez but I still couldn't get bluetooth working while WiFi works

Minimal Kernel Config?

The Pi 4 even overclocked takes a long time to build kernels for, with no guarantee of success. Perhaps it would be useful to provide a bare minimum kernel config for those interested, then let users add hardware support as they need it?

What's about "make bcm2711_defconfig"? For me the config was fitting quite well. How should the config differ?

bcm2711_defconfig seems to both set the features that the Pi itself needs and also every driver it can. Things like tons of ethernet drivers, DisplayLink USB graphics cards hardware RAID controllers and others
I created a Github issue for it with the Pi team but I don't know how they'll respond. I assumed other Gentoo users would have already shaved the kernel down themselves, so I thought it worth asking here, too
