用自己的内核镜像系统启动不起来

我的板子是tq2440，4.3寸屏，pc是win7 32系统。
我用的烧写文件是自己编译出来的内核镜像，其他文件（文件系统，uboot，logo镜像）都是光盘里的文件。
启动方式是从NAND启动。
我是按照“天嵌科技出品-Linux移植之Step By Step_V4.5_20100605.pdf”里面的步骤（step9以后没做）来做的，但是没有用教程提供的.config文件，而是按照教程里附录中的make menuconfig配置后保存后生成的.config文件，内核源代码是从官网上下载的，把编译出来的zImage.bin烧写到板子以后，出现kernel panic，具体信息如下：

我想问一下，只移植内核，其他的烧写文件都用光盘里的文件，这样有问题吗？

制作 yaffs  的工具不对，要匹配自己nand的大小，这个问题论坛中已经有很多相应的帖子了，搜索下吧

附录中的配置单有很多选项是官方源码中没有的，你要比对一下了，比如LCD屏的...当然我同意楼上的说法，你的yaffs文件系统可能没有用对

我觉得是内核配置为题。和驱动移植的问题。。。要匹配天堑的文件系统。。。要自己看一下他的文件系统的某些脚本哦。。。比如串口的名称等等

谢谢了，我按照手册上写的用busybox-1.13.0构建了文件系统，最后报错：
/dev/tq2440_serial0: No such file or directory
我看了论坛里的这方面的帖子，有人说busybox版本低，我用了最高版本busybox-1.19.3，还是同样的问题。:dizzy:

不好意思，我搞错了，修改了drivers/serial/samsung.c之后没有make，问题解决了。

亲，这样的问题很难解决的，特别是你改改动的都改动了的情况下。
