And now you expect me to guess your boot setting? Assuming neither CONFIG_NAND_U_BOOT nor CFG_RAMBOOT are set: check u-boot image size against 256k, as the offset of environment seems to be set to CFG_MONITOR_BASE + 0x40000 Or is ONFIG_NAND_U_BOOT set (would be the explanation why you mention NAND at all ...)? With u-boot in NOR this indicates a general code/configuration problem in your image.
