Adding Wandboard support to Crochet-FreeBSD has been a project of mine for a while. After this fascinating kernel fix, I can now build a working image and boot FreeBSD-Current. Here is an example boot log, and here's an image file.
The output of dmesg, with a USB wireless adapter in the board, is:

[…] part of the effort to add Wandboard support to Crochet-FreeBSD. I wrote a blog posting about it here. An explanation of how Crochet-FreeBSD boots the Wandboard is […]

Hi Tom,
thanks for posting the log – that helped tremendously in making a purchasing decision of a USB WiFi dongle 😉
Out of curiosity, have you ever investigated getting the Wandboard on-board WiFi to work?
Thanks & cheerio, Harry.
July 24, 2014 - 8:12 pm
If I recall, the Wifi chip on Wandboard isn’t yet supported by FreeBSD.
July 28, 2014 - 7:52 pm
bummer – have you had any luck with recognizing drives on the SATA port?
Thanks & cheerio, Harry.
July 31, 2014 - 8:53 pm
Haven’t tried yet.
August 13, 2014 - 3:21 pm
I dug a little deeper… The flattened device tree was missing a sata node. Adding it worked to the point I could list it at the FreeBSD loader prompt. However, there is no ahci_imx driver in FreeBSD at this point so obviously nothing attaches :-/.
Cheerio, Harry.
September 19, 2014 - 12:57 pm
Hi Harry what do you mean for “nothing attaches?” neither an usb audio card?
Thanks
November 10, 2014 - 3:35 pm
No driver attaches (since no driver exists).
Cheerio, Harry.
