I tried a testing image and it did not boot (tomato x96, 2/16g, s905x)
Armbian_5.27_S9xxx_Debian_jessie_3.14.29_xfce_20170525.img.xz could be booted from SD card but i am afraid to install it to internal storage because then HDMI would not work.
So i still keep libreelec on the internal storage but don't use the box as a desktop pc.
I wonder why libreelec works with emmc but not armbian.
