>How can I verify the integrity of the written image?
I hope you realize that if xzcat or zcat don't complain,,error out, download was OK
(the slightest change in a compressed file causes extraction errors)
so...
xzcat image |md5sum
cat /dev/SD |md5sum (replace SD with right mmcblkX_)
More likely your problem is uboot OR dtb OR boot.scr/extlinux.conf OR initrd
I would try some other (pinebookpro) dtb first, then check boot scripts
