可以不退出直接，拷贝对应的uboot文件,进行刷机
3 y) x1 {% B n7 L3 y! J或者直接在shell里面进行刷机 ...

特权模式下，第一步就不行了，然后ls -l /dev/mtd* 可以看到
crw------- 1 root root 90, 0 Jan  1 08:00 /dev/mtd0
crw------- 1 root root 90, 1 Jan  1 08:00 /dev/mtd0ro
crw------- 1 root root 90, 2 Jan  1 08:00 /dev/mtd1
crw------- 1 root root 90, 3 Jan  1 08:00 /dev/mtd1ro
crw------- 1 root root 90, 4 Jan  1 08:00 /dev/mtd2
crw------- 1 root root 90, 5 Jan  1 08:00 /dev/mtd2ro
crw------- 1 root root 90, 6 Jan  1 08:00 /dev/mtd3
crw------- 1 root root 90, 7 Jan  1 08:00 /dev/mtd3ro
brw------- 1 root root 31, 0 Jan  1 08:00 /dev/mtdblock0
brw------- 1 root root 31, 1 Jan  1 08:00 /dev/mtdblock1
brw------- 1 root root 31, 2 Jan  1 08:00 /dev/mtdblock2
brw------- 1 root root 31, 3 Jan  1 08:00 /dev/mtdblock3
但是执行有如下错误
sh-4.3# dd if=fullcat.bin of=/dev/mtd0
dd: writing to '/dev/mtd0': No space left on device
