我现在在测试一个Ti的arm9的板子，nfs方式mount rootfs时总是失败，不清楚什么原因,具体描述如下:
板子是和主机直连的 bootloader是 uboot
配置好tftp 和 nfs 目录 后 sudo /etc/init.d/portmap,sudo /etc/init.d/nfs-kernel-server正常
tftp load kernel到内存 也正常,设置好启动参数后，从内存起动
U-Boot > tftpboot c3000000 uImage
TFTP from server 128.224.159.159; our IP address is 128.224.159.100

nfs配置也是按照一般方法配置的，应该不会有什么问题
请你帮我看看可能是什么地方的问题，谢谢！ |
