按照最新版的手册，自己用busybox 1.15.2做了下文件系统，但是开机不能加载，提示信息如下，恳请过来人指导，谢谢！

试过网上说的多种方法都不行，实际上最新版的busybox修正了一些bug,linuxrc默认属性就是可执行的，shell默认配置也不是none.删除linuxrc或是自己vi linuxrc都不行。/etc/dev目录下也mknod了console和null两个设备文件，按照手册上面讲的应该不出现warning才对呀？
折腾了好几天了，实在是搞不明白怎么回事，跪求高人指点...谢谢!

严格按着PDF手册上的步骤一步一步去做就OK了，还要注意它们的标点符号。
我以前也是不行，但是按着一步一步去做了就OK了。呵呵。这是我做过来的经验。

注意两个东西：
1、etc/inittab文件的权限为可执行；
2、busybox的编译是否和内核使用的相同的编译器。

前几天终于发现出错的地方了，这里贴出来提示下大家
在passwd文件里面，喜欢自己动手移植的朋友  可能不喜欢sky这个帐号，于是改成了类似于admin等这样自己喜欢的名字
admin:/:502:502:Linux User,,,:/home/sky:/bin/sh      错误
admin:/:502:502:Linux User,,,:/home/admin:/bin/sh 正确

挺鄙视自己上述行为的，折腾了一段时间

现在感觉文件系统移植过程比较杂，自己喜欢关注最新的内核和yaffs2的源码更新，如果每次都那样手动移植，感觉很慢，而且也很容易出错。告诉大家一个比较好的方法，我体会了好久。使用一个shell脚本来处理文件系统移植的方方面面，包括后面的LCD/网络等

大体思路如下，现在还不智能，不同的电脑配置可能要做些修改，放在这里抛砖引玉了，呵呵！

呵呵，谢谢楼主，也遇到同样的问题，但现在还没有解决，正郁闷呢

主要看你的步骤，这样的问题主要两个原因：1、编译器版本不匹配（编译内核用的，和文件系统的不同）；2、烧写错了文件系统的版本。

我也有同样的问题，还没有解决呢！谁解决了帮帮吧？

我用光盘里的uboot下载光盘里的内核镜像，出现不能启动内核的问题，每次到一个地方老是重启。错误如下：

求解释:)

我也遇到了一样的问题，现在正在求解当中...

“编译器版本不匹配（编译内核用的，和文件系统的不同）”
请问
编译内核用的，和文件系统的编译器版本必须是一样的么？

我以前也是不行，但是按着一步一步 ...

这个不行啊，在配置内核system type中s3c2440 machine中只能选择TQ2440，按照教程上面选的smdk2440不行

还是调出里面带的配置发现这个问题的........
