Hi Oliver,

Nice to hear it. Thanks to Olimex I also have 2 board and make series of 
tests and customization effort based on Armbian build scripts.
I have passed through patching and customization of U-Boot, Kernel (both 
legacy 3.4.111 and mainline 4.5.2), Debian Jessie as FS, RPI Monitor etc.
All my steps are described in a couple of posts on Armbian forum where the 
main one is:
http://forum.armbian.com/index.php/topic/853-armbian-customization
There one can find all patches I have used, step by step instruction on how 
to install and boot from eMMC, SD/MMC, SATA, some measurements and tests.
One of the useful things in my opinion is U-Boot script to boot from 
available boot devices in given order and usage of user button for 
emergency boot from eMMC or SD/MMC.

Of course, my customization effort is not finished so some help in USB OTG 
activation and read-only rootfs preparation will be welcome.

Any help or notes on how the things can be done in a better way will be 
appreciated as well.

Regards
Chris
