8127 ipnc挂载nfs的问题

chimey wang

我用的是3.8版本的RDK，没做任何修改，直接编译，使用ubifs的方式可以运行，但挂载nfs则出现

TimeOut occure in boot_proc.

Program exit.

具体log如下：

将文件系统打包成ubifs烧到flash中运行则一切正常，在网上看到很多人碰到类似的问题，但没有一个确定的解决方案

根据网上的信息，已经试过以下几种解决方法，都无效：

SDK只能使用DHCP方式挂载NFS，静态IP无法挂载。 已经使用dhcp
重新编译烧写uboot和内核。 已经烧写过多次
Flash_eraseall /dev/mtd5。 没有效果
IP地址是否正确。 IP是使用dhcp的方式，确认在同一网段，而且从log上看已经成功挂载nfs，只是在启动app后出现问题
SDK编译选项默认为64位，更改成32位后重新编译。 没有效果
确定uboot配置是否与内核一致。 确认过，都是工作在FULL_FEATURE模式
使用SDK原版filesys。 直接将filesys_ipnc_dm81xx.tar.gz解压后未修改的filesys挂载，问题依旧（timeout连续打印两次）
确定文件系统是否正确。 将filesys打包成ubifs文件烧写到flash中再运行，则一切正常
Nfs文件系统确定挂载成功，只要不启动app，在nfs操作一切正常
有人说需要改Rules.mk . 我在里面只找到FS_CFG := ubifs看上去有点关系，但改成nfs后编译不成功
有人说改程序默认的IP地址与DHCP服务器同网段。不知道是指什么地方，我把system_default.h里面的默认IP改掉了，没效果
