I mean that the cape is used inside TI by TI to support NAND functionality on the AM335x processor using the BeagleBone. BUT, it take an image specifically for the thing to work. The NAND is used ot boot the UBOOT and the Kernel. I cannot say if it is used by Linux anywhere to act as a file storage or not.
Ping the e2e forum and see what response you get. http://e2e.ti.com/search/default.aspx#q=NAND+cape+support&g=264 Or, contact the supplier of the cape.
