[quote:3a1efd1b06="xsnice"]2410升级到内核2.6.11的yaffs只要做很小的改动就可以使用了.[/quote]

具体点呢，你是怎么改的?
谢谢！

redfoxlinux

我已经 把 附件 发到你的邮箱里面了  大家 有没有 详细的 说明资料 或者 流程 给大家共享一下  谢谢 各位

honesthgx

我也需要，这方面资料，，
给我一份吧，
或者，用附件贴到这里，我也下一份

我用的实验室以前买的板子，有一个做好YAFFS的根文件系统（不是卖板子提供的）。
不过，实验室的人告诉我，下到板子上，屏幕校正通不过（板子用的触摸屏，QTOPIA+LINUX）。我又不知道，改哪儿？怎么改？？

有兄弟指点一下吗，，详细一点，，发到我邮箱最好啦，，谢谢啦

现在，用的根文件系统是CRAMFS的，不能写，很麻烦。因为，我嵌入了数据库，所以需要可写的根文件系统。

谢谢大家帮帮小弟，，毕设时间不多啦！！！急啊

如果你们要看看那个YAFFS的根文件系统，我可以传给你们，有20多Ｍ，所以放不上来吧。可以，ＱＱ联系（注明理由）

没有收到阿，麻烦再发一次看看。。。。
[email protected]

我也在弄！
我的cramfs可以了。

honesthgx

我也要

jackzheng2002

下一步需要完成的工作：
video、usb等

我也要一份，谢谢

why no bady give me software which i want

请问在目前2.4.18下的yaffs该怎么做呀？
好像目前目mtd官方网站已经下不了支持2.4.18的mtd了。
我试了很多次，头都搞大了。
能不能给点指导，谢谢。

jackzheng2002

2.4.18的网上真的很多。主要是MTD的Nand的驱动的改动。。。。
其他的关于yaffs的，作为module加载或者作为rootfs都可以。。。

我的yaffs一直不对，不知道是什么原因，上面是用nfs启动的，但是不知道为什么不能创建目录

jackzheng2002

[root@fa /]# mount -t yaffs /dev/mtdblock/3 /mnt
mount: Mounting /dev/mtdblock/3 on /mnt failed: Permission denied

把目录的权限改一下看看。。。

我的把yaffs作为rootfs在上面的帖子中有，可以去看一下：）

我终于找到了问题，是在arch/arm/mach_s3c2410/devs.c中定义分区表时不能用
MTD_WRITEABLE
另外将driver/mtd/nand/s3c2410.c 中的NAND_ECC_NONE改NANE_ECC_SOFT

多谢！mkyaffs,mkyaffsimage 这两个工具一直编译
不过，（按照文档提示修改），请能给点提示，多谢

buaazy

不要用Makefile编译，直接用命令行
arm-linux-gcc mkyaffs.c -o mkyaffs
arm-linux-gcc mkyaffsimage -o mkyaffssimage
我就是这样编过的
