CONFIG_SYS_NAND_BASE CS0_BASE should be correct because the Flash is located at 0xA0000000 which should be CS0_BASE. Why do you think it is wrong? I used the patch from you out of this posting: [U-Boot-Users] [PATCH RFC 3/5] i.MX31: Add i.MX31 NAND Flash Controller driver. http://lists.denx.de/pipermail/u-boot/2008-August/038239.html They should work, or not? Do they require something else? Thanks a lot for your help.
