在YAFFS2文件系统下，从NOR FLASH（JFFS2）下CP一个2M的文件到NAND FLASH大约需要多少时间？

刚开始搞，很多不明白，望各位高手多指教阿
现在手上的s3c2410板子上已经烧好u-boot和系统，系统主文件系统是crams，同时挂接yaffs文件系统到nand flash最后一个分区，但是为什么下载到nand flash最后一个分区上的yaffs镜像识别不出来，希望高手帮忙分析下原因

真不明白错误原因是什么。我已经禁止了ecc了
这之后我又把ecc_soft这个也删除了。
错误反而更多了。
求求大虾们帮我解决这个问题。谢谢了

我的文件系统原先是 jffs2的  但板子起来太慢  所以想用yaffs2 的
但发现些上去后  多了一大堆坏块
麻烦也发我一份  谢谢！～

我用了块512MB的Nand Flash，挂载YAFFS2文件系统，扫描时从1-4096全是坏块，
是不是需要擦除？
可好像mkyaffs不能擦除2048字节大小页面的flash吧？
高手，来帮帮忙！

CPU：s3c2440

kernel:linux2.6.24

yaffs:最新版本

下载编译进内核，编译成功，下载到flash，系统正常启动，加载Yaffs文件系统，也能成功，但是将文件写到flash上后，再重启后，发现文件的大小变化了，文件或变大或变小，但变化后文件大小都变为512的倍数。

例如：yaffs文件系统加载到/mnt下

一个文件TD.o大小为190396 B写到/mnt下，当时察看属性，大小是190396 B，但重启系统后，再查看其属性，大小变为：190464B。有的文件变大，有的文件变小，不知道是什么原因，请各位大虾指点一下！！！

十分感激！！！！

我的是linux2.6.14.1内核，修改内核支持yaffs2了，但是启动的错误信息跟你的一样。烦恼了很久，现在还没解决。

lvlovelive · 发表于 2013-1-16 17:29:12

要怎么将yaffs编译进内核啊，到时下载就下载一个文件就行了，不用分别下载内核和文件系统了。有谁有相关资料的吗
