猜测可能是误删了/boot下的文件导致的，无法通过U盘启动

                               
登录/注册后可看大图

启动进入uboot输入如下命令

1. setenv bootcmd "sf probe 0;sf read 0x8000000 0x0CC000 0x434000;gpio set GPIO21;gpio set GPIO22;unzip 0x8000000 0x5000000;sf read 0x4f00000 0x0c8000 4000;"
   * M' k6 E+ c3 D; b4 n
2. setenv bootargs "console=ttyMV0,115200 root=/dev/mmcblk0p1 rootwait rw init=/bin/sh"
   
3. boot
   
4. booti 0x5000000 - 0x4f00000

复制代码

即可进入linux shell

1. # 查看存储设备
