最近在移植linux-3.0到TQ2440上,搞了几天,但文件系统死活挂载不了,特上来求救,如下为我的尝试: 
        U-boot                          zImage                               root                             挂载情况 
        天嵌的                           天嵌的                             天嵌的                              可以 
        天嵌的                             我的                                天嵌的                             不可以 
         天嵌的                             天嵌的                               我的                               可以 
         天嵌的                                我的                                 我的                              不可以 
 
 
        首先要感谢网友们,提供我一些思路去解决一个一个的问题。我试过如下方式,不过系统现在还是死活挂不上,还望各位搞过系统挂载的网友们和天嵌工程师们帮忙看看,非常感谢你们!!! 
1.根据以上尝试,很明显我的文件系统是可以用的,并且在我的内核中已经去掉其他文件系统,选上yaffs2 
2.Hardware ECC去掉或者选中都不行 
3.Kernel Features--->选上provide old way to pass kernel parameters   问题还是存在 
4.启动参数设置:Boot options--->noinitrd root=/dev/mtdblock2 init=/linuxrc console=ttySAC0  还是不行(天嵌2.6.30.4是没有设置这个的) 
 
 
如下为内核启动的出错信息:

根据他的提示,其实ISO 9660 CDROM file system support是已经添加进去的啦,搞过的高人们欢迎指点!!! |
