Raspberry Pi Zero W
+ Latest RPi Foundation Kernel
+ Latest wireless firmware from this repo

= Not working

I think this is the fatally bad part:
ieee80211 phy0: brcmf_c_process_clm_blob: clmload (4733 byte file) failed (-52)

I grabbed a usb-ethernet adapter, built a NixOS image with tailscale, and got access to it to grab dmesg logs:

  • from our nixpkgs package, this is what we copy: 
    for filename in firmware-nonfree/brcm/brcmfmac434??-sdio.*; do
  cp "$filename" "$out/lib/firmware/brcm"
done

I tested briefly, using mainline linux kernel was broken in the same way or very similar.

I suspect I'm not the only one to have noticed this:

Of course, I have no idea where ALARM is getting that file from, or why they're also seemingly unable to use the one this repo provides.

What do you get from ls -l /lib/firmware/brcm/brcmfmac43430*? The 43430 firmware has a built in CLM database so doesn't need an external clm_blob file - notice that this repo doesn't contain one.

I note that the Linux firmware repo includes a cypress/cyfmac43430-sdio.clm_blob (md5 9ff46519b8b8c2cab323322c9d983873). If you find a brcmfmac43430-sdio.clm_blob, what is its md5sum?

A fresh install of the latest RPiOS image gives working WLAN on the Zero W. Allowing it to self-update (not a quick process) fails to break it. For comparison, after a reboot the kernel log contains:

Indeed, the clm_blob is indeed coming from firmware-linux-nonfree rather than the raspberrypi-wireless-firmware package:

/nix/store/1qb4kf2jkkdw7mqzahfgnk4zmhxbvgv0-firmware-linux-nonfree-2021-08-18/lib/firmware/brcm/brcmfmac43430-sdio.clm_blob

@pelwell I do understand that RPiOS is working though, I can eventually try to provision, update, and then image the SD card and try to figure out what the diffs are in terms of installed firmware files.

@colemickens

I'm guessing, though, that RPiOS is using old firmware packages...

For some extra info:

I created a firmware-linux-nonfree package that drops out:

  • brcmfmac43430-sdio.clm_blob
  • cypress43430-sdio.clm_blob

Pushed the config over, rebooted, and now wifi works.

Where should this be fixed?

In whichever repo your OS is getting them from - I don't think it's our problem.

@colemickens

Uhm, that's upstream linux-firmware

@colemickens

I guess maybe that's my answer though? I guess I just assumed it would've been someone from... the Raspberry PI Foundation that would've pushed these blobs into linux-firmware in the first place, but maybe not? I just don't know who owns which pieces.

Before you report a problem with the upstream firmware repo, just be certain that your OS hasn't ended up with an incompatible combination of upstream and ours, which would make it an OS packaging problem.

@colemickens

Author

@pelwell aha, I think that's kind of the question I'm dancing around, as an OS maintainer, how do I determine the expected compatibility matrix?

Just pick one source - upstream or downstream. There will be differences, but each should work.
