TI中文支持网我用的是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.

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
貌似很多人都是重新编译然后烧写内核解决的，但我已经试过很多次了，都不行
Eason Wang：
1. 确保NFS就是你编译出UBIFS的一套，一个版本。
2. 是否有chmod 777 ？
chimey wang：
回复 Eason Wang:
1. 当然确保，我特意在里面加了一个说明文件来和原版区别，打包成UBIFS烧到flash里面，说明文件一样
2. 不仅我编译的不行，就算拿SDK自带的pre-build的bin也是一样的错误，我还试过3.0版本SDK的bin，也是烧flash可以，挂NFS不行，而且错误更离谱，挂NFS后会一直打印PHY=………………………………死循环
3 确定chmod 777过很多次，而且我还分别挂载过ubuntu 12.04和10.04系统上的NFS，都是一样的错误
两个不同版本的pre-build的bin都不行，我都怀疑是硬件有问题，但问题ubifs一切正常，不启动ipnc，只是挂载nfs操作或者编程都没问题

回复 chimey wang:
请问问题解决了吗？
chimey wang：
回复 Grace huang:
没解决，
你也碰到同样的问题了？也是3.8版本？
Grace huang：
回复 chimey wang:
是的呢！
Jian Li14：
您好，请问您对makefile文件修改了没？为啥我make编译无法生成ubifs文件系统（我没做修改），如果需要修改，您能简单给我指导一下吗？谢谢啦 —–本人一只挣扎的菜鸟
Ternence_Hsu：
回复 Jian Li14:
你好；
建议看一下编译目录下面的Makefile 文件；
你可以通过make make ubifs_128 来编译出ubifs文件系统来；
Chris Meng：
回复 Ternence_Hsu:
你好，
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）
解压原始的文件系统，然后make sysall，重新编译一遍，文件系统里的部分文件会更新，然后再尝试一下。uImage/uboot可以使用
我使用IPNC RDK 3.8在DM38x的参考设计上用NFS可以正常运行。使用的boot参数参考bin目录下的update.txt里面的配置。
请问你使用的硬件是Appro DM8127的参考设计么？
Louis：
回复 Chris Meng:
你好，
请尝试以下改动，ipnc_app/sys_server/src/system_control.c文件的PollingThread函数，
if(network_en && dhcp != pSysInfo->lan_config.net.dhcp_enable){ #if 0 // Louis debug SetDhcpEnable(dhcp); #endif

回复 Chris Meng:
是的，Appro DM8127
