brcmfmac error (brcmfmac43455-sdio.bin) with linux-firmware & linux-firmware-raspi2

[Jesus Munoz]

Each release of package "linux-firmware" (latest version 1.173.8 published on 2019-07-03) rewrites the wifi firmware file /lib/firmware/brcm/brcmfmac43455-sdio.bin and this error repeats:

Jul 04 14:34:42 ubuntu kernel: brcmfmac: brcmf_sdio_hostmail: mailbox indicates firmware halted
Jul 04 14:34:45 ubuntu kernel: brcmfmac: brcmf_sdio_bus_rxctl: resumed on timeout

To solve this issue, I must copy by hand the correct file brcmfmac43455-sdio.bin from:
https://github.com/RPi-Distro/firmware-nonfree/raw/master/brcm/brcmfmac43455-sdio.bin

Both packages "linux-firmware" and "linux-firmware-raspi2" contain the file brcmfmac43455-sdio.bin

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

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

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

[Dave Jones (waveform)]

Just had a look at linux-firmware-raspi2 for bionic, and the latest version (1.20190215-0ubuntu0.18.04.1) no longer contains /lib/firmware/brcm/brcmfmac43455-sdio.bin; can you confirm you're still seeing this error with the latest version?

[Jesus Munoz (jemupro)]

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