Hello as usually i have been reading of cubieboard 2 as it is new system for me. i found some talks about an issue of NAND corruption when using Linux out of sd card - and some really funny correction suggestions to that ( like instructions to reinstall android to nand, etc. ) as i built my u-boot-sunxi / linux-sunxi-3.4.n / CRUX 3.1 -based system on sd card and begun building x.org on it, i stumbled on the issue of corrupted nand = sd card based Linux did not boot after nand corrupted ( which may have happened as i tried to start x.org with udev enabled and kernel having nand support in it )... my solution to this was to build linux-sunxi-3.4.n kernel without nand support - and now it does not mind of nand being out of function ( if i some day have some use for the nand, i get back to this of course ) /mc keep-IT-simple
