重刷就好了

我刚看了一下我的好像也是这样的情况问题是冲刷的话没法双清刷机啊

执行坏块擦除，出这个提示怎么办？只是一部分

还有楼主能研究怎么从内存卡启动系统吗？就是把内存卡里放进系统进去，之后启动卡上的系统

你这个得看串口里面的具体信息才能分析原因
有很大几率是Nand的问题，用我的方法应该也能修复。

看到了关键字：NAND bbt detect factory Bad block at 5a00000。是坏块吧？但是输入nand bad然后回车或nand scrub_safe命令回车都没有任何反应，天猫魔盒TMB100a TTL救砖成功（修复Nand坏块）

需要在进入kernel 前按回车键进入命令行，另外输入法切换到英文。

“进入kernel 前按回车键进入命令行”这是哪个步骤，求解答

谢谢指点，我先试试上面旁友说的“进入kernel之前按enter”

请问“进入kernel之前按enter”这里是什么意思？是串口信息到Starting kernel ...之前按回车吗？貌似没有用
