可以不退出直接，拷贝对应的uboot文件,进行刷机
或者直接在shell里面进行刷机 ...
shell里咋刷机，不太懂了，请大佬指导

# 查看
cat /proc/mtd
# 以下命令仅作参考
# 备份
dd if=/dev/mtd0 of=uboot.bin
# 写
dd if=ubbot.bin of=/dev/mtd0

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 Jan1 08:00 /dev/mtd0
crw------- 1 root root 90, 1 Jan1 08:00 /dev/mtd0ro
crw------- 1 root root 90, 2 Jan1 08:00 /dev/mtd1

brw------- 1 root root 31, 2 Jan1 08:00 /dev/mtdblock2
brw------- 1 root root 31, 3 Jan1 08:00 /dev/mtdblock3
但是执行有如下错误
sh-4.3# dd if=fullcat.bin of=/dev/mtd0
