技术支持您好：
我使用的硬件平台是AM335X starter kit ，SDK版本使用的是04版本（ti-processor-sdk-linux-am335x-evm-04.00.00.04-Linux-x86-Install.bin）官网上最新的SDK，现在编译了uboot和kernel，现在想通过nfs挂载文件系统，现在遇到的问题是：
[ 6.172931] IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready
[ 6.202864] IP-Config: Complete:

挂载被中断了，卡在这里，请问一下这个问题是文件系统没有做好还是？我使用的文件系统是安装SDK的时候的targetNFS文件夹中的。求解答，谢谢！
