At long last, I have the Crochet-FreeBSD build for Wandboard working properly, with U-boot and ubldr. This article will serve, I hope, to document the entire process and give others a…

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: KDB:…
