我用的OK2440IV开发板，光盘里的bootloader和2.6.28的那个mouse.yaffs文件系统，编译的2.6.33内核，弄了好久，顺利启动， 挂载nfs时显示如下： # mount -t nfs -o nolock 192.168.0.245:/home/pgq/rootfs my_app # QDir::readDirEntries: Cannot read the directory: /usr/lib/ipkg/externinfo 貌似内核启动的时候就有这句，不懂～～～ 板子显示挂载成功，能看到所挂载目录中的东西，交叉编译测试程序hello.c，但在板子上运行时出现如下错误： nfs: server 192.168.0.245 not responding, still trying nfs: server 192.168.0.245 not responding, still trying nfs: server 192.168.0.245 not responding, still trying
