复制代码

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

setenv bootcmd "sf probe 0;sf read 0x8000000 0x0CC000 0x434000;gpio set GPIO21;gpio set GPIO22;unzip 0x8000000 0x5000000;sf read 0x4f00000 0x0c8000 4000;"

boot
. d2 Y1 r3 j$ b! f. P+ A
booti 0x5000000 - 0x4f00000

复制代码

即可进入linux shell

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.
