pi zero 2W wifi issues

[dictummortuum]

Hello,

I recently purchased a pi zero 2W and I'm trying to enable the WiFi.

I have followed: https://archlinuxarm.org/platforms/armv ... -pi-zero-2 and then did the dtd hack to get the pi to boot.

Wifi basically never gets up. I have a pi 4 and I put the sd card in there, updated and snooped around the journal, and I see the following:

$this->bbcode_second_pass_code('', '
[root@alarm ~]# journalctl -r | grep brcmf_fw_alloc_request:

')

Now this is weird, but I think that the tries with brcm/brcmfmac43430b0-sdio are being made by pi zero 2W and the others by pi 4.

I tried to copy the firmware files as suggested here: https://gitlab.alpinelinux.org/alpine/a ... sues/13302 , but that didn't work.

I also tried to do the same that was suggested in the second post here: viewtopic.php?f=9&t=15633&start=10 , but that didn't work either.

Can anyone please give me a hand?

You are currently running the mainline kernel. Since the RPi Zero 2W is still fresh off the production line with proper hardware support lacking upstream, try the RPi kernel instead: `pacman -S linux-rpi`.

Yes, there is no mainline support for Raspberry Pi Zero 2 W. I've send my first patch series, but don't expect anything before Linux 5.18:

The reason for broken wifi is that there are naming issues between the firmware filename and hardware revision
