I use the omap nand driver, the cpu is a AM335x with hw ecc elm. Depending on the flash type, the rom code expects BCH8 or BCH16 unless ECC is completely disabled. I'm not sure if the ecc hw is used but I see oob bytes being used. How can I verify this? --Lo _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
