无法通过nfs启动文件系统

我的UBOOT 内核 跟文件系统都是天嵌提供的 内核用的是2.6.30.4版本的 烧的是光盘下
\TQ2440_CD\出厂烧录镜像合集\奇美4.3寸屏的镜像\Linux-2.6.30.4 这个位置的镜像

文件系统试着挂了两个 一个是\TQ2440_CD\Linux资源\Linux源码包\2.6.30.4 下的
root_qtopia_2.2.0_2.6.30.4_20091216.tar.bz2
另一个是 root_qt_4.5_2.6.30.4_20091216.tar.bz2

都是解压好了的

从uboot设置好了ip跟子网掩码

但是奇怪的是 挂root_qt_4.5_2.6.30.4_20091216.tar.bz2这个包的系统能挂上 启动正常

而挂root_qtopia_2.2.0_2.6.30.4_20091216.tar.bz2 这包的系统时候 就报错 就是在uboot里边单单改了文件系统的路径 别的什么都没动 就挂不上了

启动信息如下

路径刚确实忘了设置 export的路径 不过刚加上之后也不行

后来把防火墙重新关了下

nfs服务器重启了下 就好了

也不知道怎么回事

没什么回事。
就是需要将nfs的路径设置在export文件中，重启nfs server 就以
