I just grasped that a firmware brcmfmac43436s-sdio.* will only be necessary for a future revision of the Pi Zero 2 W that is probably not yet available due to the global chip crisis anyway.
I just tested all Pi Zero 2 W boards I have here and they all have either rev1 or rev2.
The WLAN device driver has separate entries for revision 1 and 2 of the 43430 chip, so this difference should be handled well. As I understand it, there is currently no need to change something. But I will keep an eye on this and this issue will remain open. Thanks for this info!
Hi Rene, Yesterday I noticed that two different PI Zero 2 W PCBs can have different WLAN hardware: These logger lines exist on different Pis:
wlan: ether4330: chip 43430 rev2 type 1
(my Pi)wlan: ether4330: chip 43430 rev1 type 1
(the Pi of a colleague) In the next line my colleague gets this:wlan: ether 4330: can't enable HT clock: csr 50
wlan: I/O error
Now, I was wondering if this error could be related to the WLAN firmware files. But it could also be something else like a power supply or a hardware fault. (EDIT: The colleague told me he didn't copy all the firmware files in the meantime. So his problem seems to be fixed.)
Today I came accross this ticket: https://github.com/RPi-Distro/firmware-nonfree/issues/23
I tried to understand if this is of any relevance to the issue above and am not convinced. But anyway, I wanted to let you know that there are some firmware files for the Zero 2 W in https://github.com/RPi-Distro/firmware-nonfree/tree/bullseye/debian/config/brcm80211/brcm that are not yet grabbed by wget from Circle's side.
The missing files are: brcmfmac43436s-sdio.bin brcmfmac43436s-sdio.txt
And there were some changes to some files after October 2021.
Cheers, Henning
