X4412 开发板 android 4.2系统nfs启动问题

david_wang

1.我在uboot里面添加DM9000驱动成功. ubuntu上设置TFTP成功.配置内核支持nfs成功.ubuntu上设置nfs成功. 拷贝文件系统的编译结果 root下和system下的所有文件到ubuntu的nfs目录.
2.uboot命令行:
设置参数:setenv bootargs lcd=vs070cxn tp=ft5x06-1024x600 cam=ov2655 mac=00:09:c0:ff:ee:58 root=/dev/nfs nfsroot=192.168.0.11:/home/david/nfs proto=tcp flags=intr rsize=1024 wsize=1024 nfsvers=3 nolock init=/init ip=192.168.0.21::192.168.0.1::255.255.255.0::eth0n loglevel=7
tftp 40008000 zImage-nfs
bootm
系统启动,启动信息太长,我只把最后的部分贴出.

根据以上信息分析:
nfs已经挂载成功,只是在启动文件系统过程中网络连接不上了.我在网上查了很多信息,总结后我的初步结论是: 安卓系统启动过程中重新配置网络的IP了, 导致网络断开. 但我没找到在哪里重新设置的?如何禁止这个操作?

请求帮助!
谢谢!

根据信息分析：
nfs启动过程中，找一些库文件找不到。我试着到文件系统里找，也没找到这些文件。

请帮助分析，谢谢！
