我在iMX6 SabreSD开发板上，无法NFS启动了，之前一直是可以启动的，测试了网线是ok的，莫非是网卡芯片故障了？

setenv serverip 192.168.6.109
setenv bootfile uImage
setenv nfsroot /tftpboot/rootfs
setenv bootargs_base 'setenv bootargs console=ttymxc0,115200'

setenv bootcmd_net 'run bootargs_base bootargs_nfs;bootm'
setenv bootcmd 'tftpboot uImage; run bootcmd_net'
saveenv
run bootcmd
