我想使用fw_printenv来获取U-boot的环境。
$cat /proc/mtd
mtd0: 00060000 00004000 "bootloader"
mtd1: 00200000 00004000 "kernel"
mtd2: 03c00000 00004000 "root"
和
$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
然后
$ 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
你会告诉我什么是错的吗?
非常感谢。 ^^
答案 0 :(得分:0)
我明白了。
# MTD device name Device offset Env. size Flash sector size
/dev/mtdblock0 0x40000 0x20000 0x4000
