With a basic build of OpenADK for the Raspberry Pi 3, I'm getting the following error when I try to bring up wlan0.
# ifup wlan0
ip: SIOCGIFFLAGS: No such device
command failed: No such device (-19)
Successfully initialized wpa_supplicant
Could not read interface wlan0 flags: No such device
nl80211: Driver does not support authentication/association or connect commands
nl80211: deinit ifname=wlan0 disabled_11b_rates=0
Could not read interface wlan0 flags: No such device
wlan0: Failed to initialize driver interface
ip: SIOCGIFFLAGS: No such device
In /etc/network/interface, I have the following configured:
auto wlan0
iface wlan0 inet dhcp
wireless-ssid HomeWiFi
wireless-mode sta
wireless-security wpa2
wireless-passphrase XXXXXXXXXXXX
I presume there is an additional configuration for OpenADK required to enable wlan0 on the Raspberry Pi 3, but I don't see anything obvious. I have the 'iw' and 'wpa_supplicant' packages enabled, but that doesn't seem to be the issue.
