Public bug reported:
The wifi adapter does not appear under the stonking beta images, running
linux-raspi 7.3.0-1002-raspi. I've checked the linux-firmware-raspi
package is present, with the relevant firmware blobs, but wlan0 doesn't
appear. The following brcmfmac messages are present in dmesg:
$ sudo dmesg | grep brcmfmac
[ 1.981931] brcmfmac: F1 signature read @0x18000000=0x15264345
[ 1.983221] brcmfmac: brcmf_fw_alloc_request: using brcm/brcmfmac43455-sdio
for chip BCM4345/6
[ 1.983979] usbcore: registered new interface driver brcmfmac
[ 2.131189] brcmfmac: brcmf_fwvid_request_module: mod=cyw: failed 256
[ 2.144743] brcmfmac: brcmf_sdio_firmware_callback: brcmf_attach failed
The messages above are from an RPi 5, but I've verified the adapter
fails to appear on the 3B, 3B+, 4 (several memory models), and the 5 so
it appears this isn't specific to the 43455 used on the later models,
but also affects the 43430 used on the 3B (and Zero 2W, though I haven't
tested that yet).
