So you cannot read out the NAND environment, in the normal way, before serial init -- you get the default environment instead. If you are booting from NAND, I suggest using CONFIG_NAND_ENV_DST to have the NAND SPL load the environment at the same time as it loads U-Boot. If you're using some preloader other than U-Boot's NAND SPL, you'll need to see if it supports something similar. -Scott _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
