--001a113487746a949d04fd7cbd86 Content-Type: text/plain; charset=UTF-8 After some help from Ian on IRC, I have a working kernel here <http://files.khubla.com/freebsd-wandboard/FreeBSD-armv6-11.0-IMX6-r268304.img.gz>, and a bootlog here <http://files.khubla.com/freebsd-wandboard/FreeBSD-armv6-11.0-IMX6-r268304.log>; . I've attached some patch files. On Sat, Jul 5, 2014 at 12:35 PM, Tom Everett <tom@khubla.com> wrote: > ok, so I enabled iic and iicbus in the IMX6 kernel config.
