烧写天嵌科技的文件系统+你的内核，是怎么样的效果？

烧写我自己的内核加天嵌的根文件系统（烧写的是root_qtopia-2.2.0(256M))，出现以下错误

难道是我内核的问题，按照你们步奏做的，也已经修改了NANDFLASH的文件，现在不清楚有可能内核那部分有问题？

有没有选上yaffs支持

有没有选上yaffs支持

配置内核的时候选上了

文件系统做的有问题

使用的mkyaffs2img工具是否支持128M NAND FLASH的大页结构，还有制作文件结构的时候的库文件是否完全，你copy一下天嵌提供的文件系统的库文件，再试一下。

把你的内核启动的整个过程的串口信息贴出来看一下。

可能是你内核的yaffs补丁有差异，你直接复制光盘的内核中的yaffs2目录进去然后配置，然后编译，编译过程可能有报错，你针对报错的地方做些修改既可

是这样的，自己的内核实际上是直接用天嵌光盘里面的2.6.30.4的内核源代码，按照教程配置和编译了一下，那里面的yaffs2目录就是你指的光盘内核中的yaffs2目录啊，还有现在我先烧写天嵌提供的内核镜像和天嵌的根文件系统镜像成功，然后我把天嵌的根文件系统镜像换成我的根文件系统烧写，结果使用uboot里面的下载命令烧写不进去，出现下面的错误，不知道怎么回事：
