- configs/rpi3_defconfig: looks good
- dmesg: looks good (brcmfmac messages exist)
- my /etc/network/interfaces (no wireless-... entries):

# interface file auto-generated by buildroot
  
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp
  pre-up /etc/network/nfs_check
  wait-delay 15
  hostname $(hostname)

auto wlan0
iface wlan0 inet dhcp
  pre-up wpa_supplicant -i wlan0 -c /etc/wpa_supplicant.conf -B
  post-down killall -q wpa_supplicant

- my /etc/wpa_supplicant.conf (only the bare minimum):

network={
    ssid="my ssid"
    psk="my password"
}


Run wpa_supplicant with debug enabled (-dd)...double check ssid/psk?

Regards,
Peter
