hi,I have a strange question on DM6467.

When I boot DM6467, it show messages as follow :

"Sending DHCP requests ...... timed out!

IP-Config: Retrying forever (NFS root)..."

I don't know what the problem in it~

my uboot print as follows:

"ethaddr=00:0e:99:02:b5:92

ethact=DaVinci EMAC

bootdelay=3

Solved!

this is the solution of my qustion:

1. DM6467“bootargs” doesn’t accept the variable value, you have to type the location in “bootargs” directly.

Ex. nfsroot=$(nfshost):$(rootpath) (X)

nfsroot=10.100.1.1: /home/user/workdir/filesys (O)

2. install a new filesys

U-Boot shell variable substitution is a bit tricky. Some versions want {} instead of (). Single quotes around the variable should stop the substitution.

echo $(nfshost)
echo ${nfshost}
echo '${nfshost}'

Try the above at the U-Boot prompt to see which works.
