If you take a look in include/configs/xt25.h (which should be the definition of your board) this contains (e.g. on a 2010.06) ... #define CONFIG_SYS_MONITOR_LEN (256 << 10) /* 256 kB for U-Boot */ ... /* No NOR flash present */ #define CONFIG_SYS_NO_FLASH 1 #define CONFIG_ENV_IS_IN_NAND #define CONFIG_ENV_OFFSET CONFIG_SYS_MONITOR_LEN #define CONFIG_ENV_SIZE (128 * 1024) /* 128 kB NAND block size */ #define CONFIG_ENV_OFFSET_REDUND (CONFIG_ENV_OFFSET + CONFIG_ENV_SIZE) It will look for the environment at offset 256k and for a redundant one at 256k+128k. hth E. -- Elie De Brauwer _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
