Typically, when booting from NAND u-boot is configured to save the environment to NAND. You can always type 'save' and usually u-boot will print a message showing where the environment is saved. Double check the CONFIG*ENV* defines in your u-boot config file. -M _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
