Raspberry Pi 3 brcmfmac error (brcmfmac43455-sdio.bin & brcmfmac43430-sdio.bin)

[Jesus Munoz]

Package "linux-firmware" (latest version 1.173.8 published on 2019-07-03) does not contain the correct wifi firmware files /lib/firmware/brcm/brcmfmac43455-sdio.bin and /lib/firmware/brcm/brcmfmac43430-sdio.bin, so this error repeats:

To solve this issue, I must copy by hand these files from:

https://github.com/RPi-Distro/firmware-nonfree/raw/master/brcm/brcmfmac43430-sdio.bin

Raspberry Pi 3B/3B+
Ubuntu Server: 18.04.2 LTS (Bionic Beaver)
Architecture: arm64
Package linux-firmware: 1.173.8
Package linux-firmware-raspi2: 1.20180919-0ubuntu0.18.04.2

Note: Both packages "linux-firmware" and "linux-firmware-raspi2" contain the files brcmfmac43455-sdio.bin and brcmfmac43430-sdio.bin.

The same error was reproduced today (2019-07-25) when upgrading the package "linux-firmware" to version 1.173.9, as it rewrites the wifi firmware file /lib/firmware/brcm/brcmfmac43455-sdio.bin

Status changed to 'Confirmed' because the bug affects multiple users.

Thanks Jesus for the workaround, I can confirm that those two files fixed wifi on my raspi 3b+.

[Seth Arnold (seth-arnold)]

Apparently I was too hasty. Using these two files got my ip link status further along but didn't actually get me to working wifi.

[Jesus Munoz (jemupro)]

I have just upgraded the package "linux-firmware" to version 1.173.14 and it doesn't rewrite the files /lib/firmware/brcm/brcmfmac43455-sdio.bin and /lib/firmware/brcm/brcmfmac43430-sdio.bin
Therefore, I think this issue has already been solved.
