I compiled the Ubuntu Mate 16.04 kernel with custom RT patches on raspberry pi 3.

The kernel is 4.1.19-rt22-v7. Everything is working accept for the wifi drivers. They are missing from /lib/firmware.

Do I just copy the wifi modules to /lib/firmware and reboot?

    "Do I just copy the wifi modules to /lib/firmware and reboot?" -> Should more often work than not, and in the case of the Pi 3's built-in wifi, yes, but: To split hairs, firmware is distinct from the actual driver, about which the kernel is pretty picky, and the presence of the firmware doesn't mean you have the driver (brcmfmac.ko) built. – goldilocks♦ Feb 1 '17 at 1:37
  • @goldilocks I loaded brcmfmac.ko and placed the firmware and wifi is not working. Is something wrong with the modules? – ArchHaskeller Feb 1 '17 at 2:00
  • What does ip link show? – goldilocks♦ Feb 1 '17 at 2:02

    Run dmesg right after modprobe brcmfmac. You should get a line saying which firmware was used or (if none could be used) what went wrong. – Dmitry Grigoryev Feb 1 '17 at 8:53

    @DmitryGrigoryev I am dumb. I placed the firmware in the wrong place. It works now. – ArchHaskeller Feb 1 '17 at 17:30

I used the following on 15.10, but AFAIK they should already be in 16.04

cd /lib/firmware/brcm/
sudo wget https://github.com/RPi-Distro/firmware-nonfree/raw/master/brcm80211/brcm/brcmfmac43430-sdio.bin
sudo wget https://github.com/RPi-Distro/firmware-nonfree/raw/master/brcm80211/brcm/brcmfmac43430-sdio.txt

    Thanks for the answer. Could you correct the wget statement? It points at the wrong URL. – ArchHaskeller Feb 1 '17 at 17:33
