I am also a bit confused. The subject mentions revision 4, but your log shows 43430/2. Took some digging but found that numerical rev 2 matches 'b0' and rev 3 matches 'b1'. The BT part is unknown territory for me so can not clarify things there.

A separate firmware is needed, for Broadcom 43430 revision 4. This chip can be found on e.g. certain revisions of Raspberry Pi Zero 2 W. Original firmware file from IC vendor is named 'brcmfmac43436-sdio.bin', but brcmfmac and also btbcm drivers report chip id 43430, so requested firmware file name is 'brcmfmac43430c0-sdio.bin' in line with other 43430 revisions. Signed-off-by: Stefan Wahren <stefan.wahren@i2se.com> --- Hi, i'm not sure about all these mappings. All i can say is that the wifi interface of the RPi Zero 2 cames up with this patch. drivers/net/wireless/broadcom/brcm80211/brcmfmac/sdio.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-)
