In all of these images I’ve found the same thing, maybe I’m just going crazy and it requires an antenna if you’re not within 30cm of your access point? Initially it complains about the .bin/.txt for the firmware not existing:
[ 8.398295] brcmfmac mmc1:0001:1: Direct firmware load for brcm/brcmfmac43430-sdio.sinovoip,bpi-m2-zero.bin failed with error -2
[ 8.398357] brcmfmac mmc1:0001:1: Falling back to sysfs fallback for: brcm/brcmfmac43430-sdio.sinovoip,bpi-m2-zero.bin

So I then create a link to brcmfmac43430-sdio.txt/.bin and that goes away, though the errors are then as follows:
[ 277.631970] ieee80211 phy0: brcmf_fil_cmd_data: bus is down. we have nothing to do.

I’m not sure whether this is to be expected or not? Bluetooth looks to be working, though the devices I’ve been able to pair with are closer than my AP. Placing my phone as a mobile hotspot directly next to the board results in a connection so maybe I’ve just been going crazy over nothing and it just requires an antenna to be useful?
Well, I’ll edit to add that yup, it just seems that the antenna was the problem here. I stole one from another board and there we have it, lots of networks showing up… Should have tried that earlier!
