Hi, I have to get environment variables in linux from uboot. For that i did make cross compile on env tools in my uboot(uboot-toradex).after this i executed the fw_printenv in my linux it is giving like following,

sh-4.2# fw_printenv Too few good blocks within range

and my fw_env.config file is,

# NOR example # MTD device name Device offset Env. size Flash sector size Number of sectors #/dev/mtd1 0x0000 0x300000 0x40000 #/dev/mtd2 0x0000 0x4000 0x4000

# MTD SPI-dataflash example # MTD device name Device offset Env. size Flash sector size Number of sectors #/dev/mtd5 0x4200 0x4200 #/dev/mtd6 0x4200 0x4200

# NAND example #/dev/mtd0 0x4000 0x4000 0x20000 2 /dev/mtd5 0x0000 0x200000 0x40000 2

and in linux,

sh-4.2# cat /proc/mtd dev: size erasesize name mtd0: 1e7c0000 00040000 "USR" mtd1: 00300000 00040000 "BCT" mtd2: 00040000 00040000 "PT" mtd3: 00200000 00040000 "EBT" mtd4: 00040000 00040000 "BMP" mtd5: 00200000 00040000 "ENV" mtd6: 00800000 00040000 "LNX" mtd7: 00040000 00040000 "ARG"

please give me a solution.
