深思

jffs2每次要扫描整个分区，超慢，用yaffs2就快多了。

    到http://www.aleph1.co.uk/cgi-bin/viewcvs.cgi/yaffs2/网站下载YAFFS2源码（左下脚），根据yaffs2/README-linux-patch文件的提示将yaffs2加入linux中，所有文件在fs/yaffs2目录中。
    文件系统生成工具在yaffs2/utils目录，mkyaffsimage生成是512＋16页配置的（基于YAFFS），mkyaffs2image是2K页配置的（基于YAFFS2）。
    修改mkyaffsimage.c中与OOB相关的错误，关于该错误的分析见hiboy的博客：

    必须修改2410 nand驱动中ECC检验方式为NAND_ECC_NONE，而在YAFFS2内核编译时选择了Lets Yaffs do its own ECC。

    mkyaffsimage ./busybox-1.14.1/_install/ ./rootfs.arm.yaffs

你的这些步骤我都试过的.

不知道你linux内核编译的时候,有哪些特殊的选项?
busybox1.14.1一堆编译错误,没时间弄了,而且你是static编译的吧,能试下busybox1.7.0么,用share lib方式?
mknandflashdump是否做过修改?
mknandflashdump将根文件写在nand.dump某个地址上, skyeye.conf中还要定义这个root.fs的mem bank么? mem bank我以前好像没有加上0xC0000000UL, 写的是flash分区的地址.

skyeye.conf应该和你jffs那个帖子里一样吧?

要是能写个详细的文章就好了.

深思

内核2.6.28，直接用的ubuntu9.04源下的，没有什么特殊选项
busybox-1.14.1 采用的动态库编译。
mknandflashdump修改过见前帖。
nandflash: type=s3c2410x,name=K9F1208U0B,dump=./nand.dump
不需要别的mem bank

你直接通过RAMFS可以起来么？

LLClown

可以从ram启动的.

不过按照以前的步骤,从新编了下,居然跑不起来了,
start addr is set to 0xc0008000 by exec file.
到这就不动了.以前也遇到过,不知改什么内核配置就可以了,现在忘了.

能把你的root文件夹打个包,我试下

烧写root.yaffs. 需要格式化整个yaffs.nand么?用什么工具?
./mknandflashdump root.yaffs yaffs.nand 0x400000

深思

用附件中的工具
#!/bin/sh

echo "mkyaffsimage"
mkyaffsimage /home/elf/busybox/busybox-1.14.1/_install/   /home/elf/busybox/rootfs.arm.yaffs
./mknandflashdump ./rootfs.arm.yaffs ./nand.dump 0xe00000 yaffs

echo "done"

LLClown

3xs!
终于可以了, 以前./mknandflashdump忘了最后一个参数yaffs
./mknandflashdump root.yaffs yaffs.dump 0x400000 yaffs

btw: 能不能整个格式话yaffs.dump文件呢,要不然会有很多Bad eraseblock.
应该是没格式化吧?
