nfs booting error on i.MX6 sabresd

[jinu]

hi, everyone

I have a sabresd i.MX6 board.

But it isn't work on NFS.

I attach uboot env and boot log.

How can I fix this error?

Sending DHCP requests ., OK

Add rootwait to bootargs_nfs and it should be OK (if NFS server is set up properly).

[1990rahulreddy]

how to add rootwait

U-Boot > setenv bootargs_nfs ‘setenv bootargs ${bootargs} root=/dev/nfs

ip=dhcp nfsroot=${serverip}:${nfsroot} fec_mac=00:04:9F:00:EA:D7’

to this...
