找出相對應位置

cat /proc/mtd

dev:    size   erasesize  name
mtd0: 00020000 00010000 "RedBoot"
mtd1: 003c0000 00010000 "linux"
mtd2: 002a0000 00010000 "rootfs"
mtd3: 00040000 00010000 "ddwrt"
mtd4: 00010000 00010000 "nvram"
mtd5: 00010000 00010000 "board_config"
mtd6: 00400000 00010000 "fullflash"
mtd7: 00020000 00010000 "fullboot"

 

mtd Usage: mtd [<options> ...] <command> <device>

 

The device is in the format of mtdX (eg: mtd4) or its label.

mtd recognizes these commands:

        unlock                    unlock the device

        erase                     erase all data on device

        write <imagefile>   write <imagefile> (use - for stdin) to device

Following options are available:

        -r                      reboot after successful command

        -f                      force write without trx checks

        -e <device>             erase <device> before executing the command

 

Example:

To write linux.trx to mtd4 labeled as linux and reboot afterwards

mtd -r write linux.trx linux
