关于nfs挂在出现停止不运行问题

lys0099

开发板是OK335XD工业级，在nfs模式下，下载原来的256M uImage文件，之后运行一段程序后，就停止了，参见附件运行信息。这个uImage文件是光盘原来的文件，通过SD卡烧录是能够正常运行的，只是通过tftp下载后运行不了，
设置启动参数如下：
#setenv serverip 192.168.1.210 （设置ubuntu服务器的ip）
#setenv ipaddr 192.168.1.216 （设置开发板的ip）
#setenv bootargs console=ttyO0,115200n8 root=/dev/nfs nfsroot=192.168.1.210:/nfs_rootfs,nolock rw ip=1
92.168.1.216:192.168.1.210:192.168.1.1:255.255.255.0::eth0:off screentype=R screensize=800x600-vga
（nfsroot=192.168.1.210:/nfs_rootfs中的192.168.1.210为ubuntu服务器ip，/nfs_rootfs 为ubuntu下所建的
存放文件系统的路径，192.168.1.216是开发板的ip）
#setenv bootcmd “tftp 80000000 uImage;bootm 80000000”
#save  保存环境变量
