Running PSP 4.02.00.07 on DM3730, I'm attempting to boot from an NFS mount using the following bootargs:
setenv nfsargs 'setenv bootargs mem=80M@0x80000000 mem=128M@0x88000000 console=ttyO0,115200n8 noinitrd rw ip=${ipaddr}:${serverip}:${gatewayip}:${netmask}:${hostname}:eth0:on root=/dev/nfs nfsroot=${serverip}:/home/glennw/workdir/filesys_new,nolock,rsize=1024,wsize=1024 psplash=false mpurate=800 vram=10M omapfb.vram=1:10M omapfb.debug=y proto=tcp nfsrootdebug'
Boot debug output shows:

This indicates that the NFS mount process is throwing an EHOSTUNREACH error.
However, the host is most certainly reachable from this board. I can tftp to it from U-Boot, and if I boot the kernel into a Ramdisk or Flash filesystem, I can not only ping the host server, I can also do this:
busybox mount -o rw,tcp,rsize=1024,wsize=1024,nolock -t nfs 192.168.0.50:/home/glennw/workdir/filesys_new /mnt
...which works perfectly fine.
Any thoughts on why the NFS root mount fails when everything else seems to be working?
