I manage to get my wifi working on raspberry pi zero 2w on a buildroot image.

this is my /etc/wpa_supplicant/wpa_supplicant.conf:

Code:

country=ZAupdate_config=1network={    ssid="Home"    psk="password"    key_mgmt=WPA-PSK}
this is my /etc/network/interfaces:

Code:

auto loiface lo inet loopbackauto wlan0iface wlan0 inet dhcp    wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
and this is my /etc/init.d/S40network

Code:

#!/bin/shcase "$1" in    start)        echo "Loading brcmfmac module..."        modprobe brcmfmac        echo "Bringing up loopback interface..."        ifup lo        echo "Starting wpa_supplicant..."        /usr/sbin/wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf        echo "Starting dhcpcd..."        /sbin/dhcpcd wlan0        ;;    stop)        echo "Stopping dhcpcd..."        /sbin/dhcpcd -k wlan0        echo "Stopping wpa_supplicant..."        killall wpa_supplicant        echo "Taking down loopback interface..."        ifdown lo        ;;    restart|reload)        $0 stop        $0 start        ;;    *)        echo "Usage: $0 {start|stop|restart|reload}"        exit 1        ;;esacexit 0
and this my /etc/dhcpcd.conf:

Code:

duidpersistentvendorclassidoption domain_name_servers, domain_name, domain_searchoption classless_static_routesoption interface_mtuoption host_nameoption rapid_commitrequire dhcp_server_identifierslaac private# Configuration specific to wlan0interface wlan0    dhcp
All these are added under your rootfs overlay folder to be added to build.

If there a better way let me know, but this worked for me.
