Cubieboard2 (20120909 NAND) boot fails with 'miniroot-cubie-64.fs'
installation image.
Debian linux have been successfully installed on the specific hardware.
So, it is not likely a hardware issue.
There are several revision in Cubieboard2.
(http://dl.cubieboard.org/model/CubieBoard2/How To Distinguish Your
CubieBoard2 Version.pdf)
And, the only revision at hand is '20120909 NAND', the oldest.
