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，
simonliu009 发表于 2015-4-11 17:53
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
18994992234 发表于 2015-5-31 20:02
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
{znds6}起来，楼主人呢？

终端窗口出现字符就开始猛按回车，直到出现#提示符，必须不能出现starting kernel,也就是阻止系统跑到kernel。

thank you{:87:}
能提供一下 TB100A 的 UBOOT 吗？我按你帖子格式化了一下NAND，SPI掉了，开机蓝灯黑屏，TTL提示显示没启动系统，短接刷入ROM、REC等均没用。
