  • So what did you install in NAND flash for a rootfs, and at what NAND address is it written at? Do you have a boot log of the last working kernel and rootfs? FYI UBIFS is preferred over JFFS2 when using NAND. E.G. take a look at http://www.at91.com/discussions/viewtopic.php/f,12/t,23189.html – sawdust Nov 08 '14 at 09:22
