启动进入uboot输入如下命令
setenv bootcmd "sf probe 0;sf read 0x8000000 0x0CC000 0x434000;gpio set GPIO21;gpio set GPIO22;unzip 0x8000000 0x5000000;sf read 0x4f00000 0x0c8000 4000;"
setenv bootargs "console=ttyMV0,115200 root=/dev/mmcblk0p1 rootwait rw init=/bin/sh"
boot
booti 0x5000000 - 0x4f00000即可进入linux shell
# 查看存储设备
ls -l /dev/sd
# 挂载
mount -t proc /proc
mount /dev/sda4 /mnt
# 拷贝文件
cd /mnt
cp armada-3720-customer0.dtb /boot/
cp Image /boot/
# 退出
exit重新插拔电源后恢复正常,uboot信息如下：

补充下:这样修改后，只能一次有效请删除mmc 0:3 分区的rootfs.tar.bz2和upgrade_eli_38.img文件。
或者直接在linux shell里面刷写新uboot

是还是原样子，启动还是end Kernel panic - not syncing: No working init found.Try passing init= option to kernel. See Linux Documentation/init.txt for guidance.
完全按照您的步骤做的
