内核移植失败

以前使用天嵌的镜像移植内核和文件系统，移植成功。现在想自己编译内核，所以完全按照pdf教程来做，可是没有成功。内核移植到开发板后无法启动系统。串口显示如下：

然后就不动了，也不再显示任何信息，开发板的屏上也是花屏。我又换成了以前用天嵌提供的内核下载进去，系统就正常了。这说明文件系统是没有问题的。而是内核的问题，然后我按照4.5版本的附录5的配置单重新配置，还是不行而且有的选项找不到。到底是哪里出了问题？
我分析了这个串口信息和成功的时候的信息，主要区别在后边：
VFS: Cannot open root device "mtdblock2" or unknown-block(31,2)
Please append a correct "root=" boot option; here are the available partitions:
1f00             256 mtdblock0 (driver?)
1f01            3072 mtdblock1 (driver?)
1f02          257024 mtdblock2 (driver?)
如果是成功的话，串口打印的信息应该是
VFS: Mounted root (yaffs filesystem) on device 31:2.
我想应该是文件系统没法挂载的问题，是内核没法决定mtdblock2就是在unknown-block(31,2)这里，可是我不知道具体的哪里出了错误，希望亚瑟王能提供帮助。
再次提醒：内核是我按照教程上下载的2.6.30.4然后自己制作的  文件系统是使用天嵌提供的而且如果用天嵌的内核是测试成功的，但是配上自己的内核就不行
我重新对照了我的内核配置表，发现以下几项和附录5不一样：
没有SKY2440/TQ2440 Board Hello module
也没有Video capture adapters下面的OV9650Driver选项
也没有LCD select(3.5inch)选项
其他涉及EmbedsKy的项目也没有
而其他的都和配置单一样。版主看看是怎么回事啊？

你这个问题我也遇到过 是因为bootloader、kernel、yaffs的地址位置在bootloader上已经写死了，你按照天嵌内核中的地址来把内核中nandflash中各个部分的分区地址改好，就可以了

那在哪里可以看到nandflash的分区地址啊？谢谢了

我服你了，同样一个问题发了不下于5个帖子，看你的帖子回你的帖子至少浪费了20分钟。不要重复发帖，发一个帖子就行了，肯定会回复你的。

真实不好意思哈  不过是心急了  弄了好长时间 到现在都没搞定，苦恼啊，不过暂时先放下，继续其他的方面哈。我总是觉得自己的问题很难弄，其实提出这个问题的时候我已经把论坛上的关于这方面的帖子都看过了。方法也都试过了可是都不行，而且教程不知道看过多少遍了，实在没办法才发帖的，可是现在问题依然存在，打算先把移植的问题放下，看视频教程。
