Wifi on the Cubox-i with an image built using Yocto?

I'm building my Linux image for the Cubox-i4pro using Yocto and the fsl-community-bsp-platform (from - using the master branch).

It's working pretty well, but I can't get Wifi working. There is no wlan0 device.

The wifi is enabled in the kernel config, and the firmware files seem to be in the right place, but there are no messages related to brcmfmac in dmesg during bootup.

After booting up I get this message on the console regularly: "brcmfmac: brcmf_sdbrcm_bus_watchdog: Enter"

Any ideas on what I need to do to make the wifi work?

Has anybody managed to get the wifi working on a Cubox-i with Yocto?

(Note: The Yocto build is using the 3.0.35 kernel - I've only seen the wifi working with Arch Linux on the 3.10 kernel).
