help: 帮忙看下为什么skyeye从nand flash挂载rootfs失败

LLClown

linux2.6.20 (添加了yafss2 / defs支持)
skyeye 1.2.5
busybox1.7.0
可以从ram加载根文件initrd.img
现在想模拟从nand flash上加载yaffs根文件.

提示:
VFS: Cannot open root device "mtdblock2" or unknown-block(31,2)
Please append a correct "root=" boot option
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(31,2)

mtdblock2改成mtdblock/2也还是同样的错误.

附件是skyeye.conf和log.

把root改成设备号31:02,

现在出现这个提示:
No filesystem could mount root, tried: ext2 msdos vfat romfs
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(31,2)

这个应该是指我的根文件没做对吧(我也是按着步骤做的,应该不会错的啊),
还是这个分区要格式化成yaffs呢? 这个分区的大小是比根文件要大些

initrd.img 下面运行时，能否 mount 你的 root 分区？

LLClown

yaffs选成了动态加载,改成静态编译.

现在的错误是,
VFS: Mounted root (yaffs filesystem).
Freeing init memory: 116K
Warning: unable to open an initial console.
Failed to execute /linuxrc. Attempting default...
Kernel panic: No init found.  Try passing init= option to kernel.

我又重新编了root文件系统,一直都是这个错误.

jiangtao9999

/dev 里面有什么？
Linux 启动至少必须有 console 和 null 两个设备。

LLClown

有console null ttySAC0 mtdblock0 mtdblock1 mtdblock2
下载了个别人做好的yaffs2根文件,还是报一样错.

网上查到有人说makeyaffsimage有问题,和2.6.2x不匹配,按照修改,有编不过makeyaffsimage.

linux好是好,就是真,乱, 郁闷啊.

jiangtao9999

不是乱，是你没弄明白而已

你确定 /dev 里面的都是设备节点而不是普通文件？
另外注意提示
Failed to execute /linuxrc. Attempting default...
不能运行 /linuxrc ？

LLClown

mknod 生成的console null.
应该还是flash有问题,没能正确读出文件, 网上看到片文章,说yaffs  flashmount上后,只有lost+found目录. 我想我的应该也是这样.

但我也试了别人好用的根文件系统啊, 郁闷

LLClown

我觉得应该是skyeye对flash的模拟有问题,或者是skyeye.conf对flash的写法不对.
谁能帮我看看skyeye.conf写对了麽? 或者有谁在skyeye下mount上yaffs flash麽?
我又试了下linux2.6.14,从ram启动linux后, 想mount yaffs失败.情况和linux2.6.20一样.

是还要mknandflashdump模拟烧写制作flash dump文件??
