This is a Wandboard-Quad, but installed on an EDM1-FAIRY carrier with
USB wireless keyboard/Mice plug.

Probably because of the partition resizing, which happened on first boot.

Second boot worked better, but booting hanged after devd.

Welcome to FreeBSD!

Before seeking technical support, please use the following resources:

o  Security advisories and updated errata information for all releases are
   at http://www.FreeBSD.org/releases/ - always consult the ERRATA section
   for your release first as it's updated frequently.

o  The Handbook and FAQ documents are at http://www.FreeBSD.org/ and,
   along with the mailing lists, can be searched by going to
   http://www.FreeBSD.org/search/.  If the doc package has been installed
   (or fetched via pkg install lang-freebsd-doc, where lang is the
   2-letter language code, e.g. en), they are also available formatted
   in /usr/local/share/doc/freebsd.

If you still have a question or problem, please take the output of
`uname -a', along with any relevant error messages, and email it
as a question to the questions at FreeBSD.org mailing list.  If you are
unfamiliar with FreeBSD's directory layout, please refer to the hier(7)
manual page.  If you are not familiar with manual pages, type `man man'.
