2.6.22挂载yaffs文件系统的问题

dorice

最近在移植linux到三星的s3c2410上，不过死活不能加载根文件系统，网上的方法都试过了，好像都没有什么效果，希望大家给我一点建议，究竟是哪一部分出了问题？下面就是我的输出信息：

yaffs文件系统是用最新的yaffs2源代码编译出来的mkyaffsimage工具生成的，里面放的是最新版busybox。大家觉得是哪一部分出了问题？bootloader？kernel？还是根文件系统？

dorice

换成cramfs后可以正常进入系统，把yaffs烧到另一个分区，用mount查看，发现里面只有一个lost+found，是不是烧写不对？我用过两个声称支持yaffs的bootloader烧写都是出现同样问题。
另外用jffs2的时候也有问题，出现一大堆，感觉应该是文件系统制作有问题，我用的命令是：

mkfs.jffs2 -l -n --eraseblock=0x4000 --pad -d rootfs -o rootfs.jffs2.new

flash是三星的64M大小的K9F1208 Nand。

elzo

同问一下，我这个问题困扰好久了。

elzo

而且我是mknod console c 5 1过了
null zero也有

elzo

我用2.6.13有devfs的可以加载yaffs作rootfs。
2.6.22.X都不行，郁闷了很久了。

是不是由于/dev下没有console设备导致。创建设备节点console和null再试一下。

elzo

我都加过的。

不要怀疑yaffs啦
真得郁闷了我很久。

怎么一直没人看出来？
看到google的android也用yaffs啦，还是2.6.23的ker

dorice

2.6.3, 2.6.22.12, 2.6.23.1我都试过，全部一样的问题！
