Broadcom BCM4356 wifi chipset firmware is not working

[Jean-Pierre Thomasset]

Hello,

After upgrading to Ubuntu 18.04 I got an issue with the wifi chipset (Broadcom BCM4356) not initializing properly.

Here is the error I got when loading the driver brcmfmac:

```
[ 8189.092819] brcmfmac: brcmf_fw_map_chip_to_name: using brcm/brcmfmac4356-pcie.bin for chip 0x004356(17238) rev 0x000002

```

As seen here https://answers.launchpad.net/ubuntu/+question/668329, I reverted to the previous linux-firmware version and then the wifi chipset is working:

Previous firmware package: https://packages.ubuntu.com/artful-updates/linux-firmware

The problem seems to have been reported to the linux-wireless mailing list but no fix has been committed apparently : https://www.spinics.net/lists/linux-wireless/msg168687.html

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

[Jean-Pierre Thomasset (jpthomasset)]

I still have the issue with the latest version of the linux-firmware package (1.173.1). However the firmware (brcm/brcmfmac4356-pcie.bin) in the official linux-firmware repository solves my issue.

The fix was introduced in the following commit: https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/?id=fe4a9d49d44c40a7bc32cdd9529e6a5c8ac92519

Regards,
Jean-Pierre.

@jean-Pierre: Thank you very much, manually overwriting the .bin file with the one form the commit you mentioned fixed it. Lets hope the fixed is packaged for 18.04 soon.

Fix not working for me, i still get
[ 145.578369] brcmfmac 0000:04:00.0: firmware: failed to load brcm/brcmfmac4356-pcie.clm_blob (-2)
[ 145.578379] brcmfmac 0000:04:00.0: Direct firmware load for brcm/brcmfmac4356-pcie.clm_blob failed with error -2

Anyone knows something more about this?

[Jean-Pierre Thomasset (jpthomasset)]

@orestis-8 Did you try the previous ubuntu package or the newest files from the official linux-firmware git repo ?

[Orestis Ioannou (orestis-8)]

I tried the latest bin from the linux-firmware with no luck.

[Alex Hung (alexhung)]

I recalled trying the firmware in 16.04 (.5?) and it worked. You can boot from USB and copy brcmfmac4356-pcie.bin.

Does anyone know this problem was resolved or not?
My system is Kubuntu 21.10.
