DART6UL - imx6ull wlan0 not available

I'm working with the DART-6UL from Variscite, which has the i.MX 6Ultralite processor. I've built Yocto Morty 2.2.1 Linux distribution from Variscite for it and the image is "core-image-minimal". The kernel version is 4.1.15.


When I try to set wlan0 interface up, I get the following error:


   root@imx6ul-var-dart:~# ifconfig wlan0 up

   ifconfig: siocgifflags: no such device


In the device tree everything seems to be added for the wifi to work. And from the OS that came flashed from the manufacturer I know that the hardware is fine and I can connect to wireless networks without problems.


What should I add to my "core-image-minimal" image to get a working WiFi?


Thanks in advance,
