utiliser fw_printenv pour obtenir l'env U-boot

Question

Je veux utiliser fw_printenv pour get env de U-boot.

$cat /proc/mtd

mtd0: 00060000 00004000 "bootloader"
mtd1: 00200000 00004000 "kernel"
mtd2: 03c00000 00004000 "root"

et

$vi /etc/fw_env.config

# Configuration file for fw_(printenv/saveenv) utility.
# Up to two entries are valid, in this case the redundand
# environment sector is assumed present.

# MTD device name       Device offset   Env. size       Flash sector size
/dev/mtd0               0x0000          0x60000         0x4000

puis

$ fw_printenv

Warning: Bad CRC, using default environment
bootcmd=bootp; setenv bootargs root=/dev/nfs nfsroot=${serverip}:${rootpath} ip=${ipaddr}:${serverip}:${gatewayip}:${netmask}:${hostname}::off; bootm
bootdelay=5
baudrate=115200

voulez-vous me dire ce qui ne va pas?

Merci beaucoup. ^^
