根文件系统移植了N遍，就是不成功。

根文件系统移植了N遍，就是不成功。
我不管是按照第二版还是第三版移植。反正就没有一次成功过。这是为什么呢？它到这里就不动。

标点符号绝对正确,因为我把光盘里的根文件系统改成PDF里的内容后(也就是改了inittab  rcS  文件，其他就是用光盘里的文件了),它确能成功.为什么我自己移的就是不行.
怎么会这样呢？  linuxrc用什么软件可以查看它里面的内容呢？
谢谢大家！

linuxrc是一个链接文件，它连接到bin目录下的busybox

我第一次移植的时候，出现的情况和你一摸一样的。主要原因还是etc目录的文件制作问题。
我重新制作一遍，有些文件内容是从busybox的文件里面拷贝过来的，除了bin sbin usr linuxrc这几个文件。上次说，给你发邮件的，忘了，中午我切换到ubuntu下，给你发一份我的文件系统。

我把你给我的文件系统解压到系统下，然后再mkyaffsimage_2 rootfs rootfs.yaffs
再把它烧到NAND Flash里，结果和我的一样，还是不行。到了

到这里.也不动了.晕呀!
这是为什么呢?

串口要和你内核的一样。。。

天嵌的是TQ2440_serial，我的文件系统不是这个。你自己看看。。。

串口应该没有选错，命令行传递过去的也是串口0呀，/etc/inittab   里的也是serial0呀，找不到原因，头大呀。

哦，我明白了，那个busybox不一样哦！！我用的是busybox1.15版本的，而且使用4.3.3编译器编译的busybox

额，看你内核启动信息，你内核用的是2.6.25.8，编译器版本是4.3.3，按道理说，应该没问题的，很奇怪的。我用的是2.6.30.5的内核。编译器是4.3.3的，注意第三版里面有个注意事项EABI。busybox 1.15 .你的就是出问题，我的就没有问题，想不通。。。

我用别人的busybox生成的（bin linuxrc sbin usr）的这些文件，它就能行，我用我自己的busybox生成的就不行。但是用人家会生成如下错误：

你检查你的busybox是用什么编译器编译的，然后版本是不是太低了。

怎么看是那个编译器编的？

编译器版本为：gcc version 4.3.3 (Sourcery G++ Lite 2009ql-203)
是不是用这个呀？亚瑟王
谢谢 亚瑟王！

是的，编译器是用的4.3.3的。
