移植linux-2.6.33.5到TQ2440的注意事项

最近先移植linux-2.6.34到TQ2440，不成功，然后继续移植linux-2.6.33.5，还是不行，都是Failed to execute /linuxrc. Attempting defaults的错误。现总结解决过程：

1、根文件系统使用TQ2440自带的内核是可以启动的
2、linux-2.6.33.5可以启动cramfs格式的根文件系统
3、因为我的是64M的Nand Flash，所以不能选择Hardware ECC，也不要改成ECC_NONE
种种迹象表明，是挂载yaffs2文件系统出了问题，最终突然明白，由于我采用的是Git仓库中的最新的yaffs2代码，于是，我换了个旧点的yaffs2编译，问题终于解决。

提醒大家：遇到Failed to execute /linuxrc. Attempting defaults的问题，除了网上说的原因外，你还要看看yaffs2本身是否和内核版本匹配。

如果大家需要linux-2.6.33.5，我可以把代码贴出来。

给你加精了，赞一个。

不错，谢谢

这个 必须 顶
都卡在 这几天了 晚了得 回去了
明天 来 试一下

我用的也是最新的git仓库的yaffs2代码，开启硬件ECC没问题，估计和你的64Mnand 开启有关系吧，我的是256的。

经验分享，可以说是精华。顶！

自己动手移植linux-2.6.34.7版本的内核，mkyaffs2image工具是自己做的，但是为什么不行呢，打印信息如下
