Hi,
I have an rpi4b otherwise running fine with openbsd 7.8.
I can't seem to get bwfm interface detected in dmesg though.
This is for the onboard wifi.
I thought installing the firmware should at least make it show
in dmesg - is this assumption incorrect?
A thought did occur but I can't check at the moment - but does
wifi need to be enabled via booting to eg RaspiOS and running raspi-config?
I thought it wouldn't be relevant for OpenBSD. maybe I'm wrong?
Having looked at the man page and searched the internet, I can't see where
to go from here. Can anyone clue me in please? Here's output from UKC and full
dmesg:
