<br><font size=2 face="sans-serif">Hi,</font>
<br>
<br><font size=2 face="sans-serif">We are using MPC8272 based target board,
we are trying to mount montavista Linux version 2.6.10 kernel image (with
NFS enabled) to our target board,</font>
<br><font size=2 face="sans-serif">we are setting following bootargs in
bootloader </font>
<br>
<br><font size=2 face="sans-serif">"setenv bootargs root=/dev/nfs
nfsroot=192.168.178.110:/opt/montavista/pro/devkit/ppc/82xx/target ip=192.168.178.234:192.168.178.110:192.168.178.47:255.255.255.0:cashel:eth1:off"</font>
<br>
<br><font size=2 face="sans-serif">when we boot the board, it is not able
to mount nfs file system to board, but the same image and configuration
works with MPC8272ADS board.</font>
<br><font size=2 face="sans-serif">please suggest me, what could be the
problem.</font>
