It looks like the problem is that -EUCLEAN is a non-fatal error (indicates a correctable ECC error). The code invoked by the "nand read" command succeeds if nand_read() returns either 0 or -EUCLEAN, but readenv() is missing this check. -Scott _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
