Oh, sorry then. I thought you were related in some way to Circuitco. Anyway, looking at the NAND cape wiki page, there's a sign saying there's no software support for the cape.
Odd as it sound, maybe the cape is really not usable :-( In case anybody has this same issue, there are some patches floating around from Pekon Gupta to support x16 NAND in U-Boot, but they are still work-in-progress and could need some tweaking: http://lists.denx.de/pipermail/u-boot/2013-September/162294.html Thanks!
