I would like to test a build for
Review of CX-S806 TV Box Powered by Amlogic S812 Processor
Kerber has it working ( in older OE build ) if it would make it easier for you to build for Libreelec build ?
If I flash from your img file (LibreELEC-RPi2.arm-8.0-devel-20160721.img) and boot up my pi, it hangs at resizing storage.
However, if I first flash LibreElec (v7.90.003 Alpha), boot up my pi, and then load your TAR file in /storage/.update then all works just fine.
If it matters, I am using a Pi 3 but I *think* I may have tried a couple weeks ago with a Pi 2 and had the same results but I can't recall for certain.
Other possibly relevant details:
Patriot 64GB microSDXC
Just wait ! Resizing took "forever" but then it's fine
