yaffs文件系统挂载失败~~卡了很长一段时间，求助！

  在制作完yaffs烧写到板子之后，出现了：kernel panic：unable to mount root fs on unknow-block(31,2)
   我用的是天嵌提供的uboot烧写内核以及yaffs文件系统，我想请问一下，nand flash的分区设置是否在
“/arch/arm/plat-s3c24xx/common-smdk.c"中static struct_partition_default_nand_part[]="这个结构体函数当中？我按照step by step进行修改以及自己修改过nand flash分给yaffs的空间，还是出现了上述挂载跟文件系统失败的情况，这个问题已经卡我很长一段时间，请求大家帮忙！~
   我自己的理解：按函数分配上看，yaffs root应该是最后被写入flash的，flash尾端还有很大的一段存储空间，应该不存在“给yaffs分配flash不足的情况”，所以真的不知道是什么问题，求助大家~~非常感谢！

是不是你制作yaffs的工具不对，要根据自己的nand flash的大小来决定使用哪个工具的，论坛中已经有不少这样的问题了，你搜索下看看

挂载yaffs2时要首先打一个补丁的，你看看你的fs文件夹里有没有yaffs2文件夹

有，已经打补丁了的(fs文件夹里有没有yaffs2文件夹)，后来继续反复看了配置的问题，还是出现这个问题！~256m的flash不是用的是busybox构建？:Q
求大神，求助！！~我的qq：229349154

你烧写天嵌科技的文件系统之后，能正常启动吗？

把你的内核启动参数
  还有内核启动打印出来的信息贴出来

kernel版本说一下

之前我试过直接用关盘里面的文件系统，发现还是不行啊

我是直接用天嵌自带的uboot啊，导入里面自带的内核Zimage.bin还是出现上述内核启动错误:Q

这个貌似经常出问题呀，望高手指点！！！！！！

12楼的亲，你烧写你自己的内核，用天嵌科技的文件系统，能不能启动啊？
