Hi all,
 
    I am having a MPC8280 based Freescale evaluation board (A & M
rattler) running U-boot. It is successfully getting the ip address using
DHCP. (in Uboot).
 
When I am trying to boot the board with Linux, it continuously sends
DHCP request. The boot args which I am giving are:
 
bootargs=root=/dev/nfs nfsroot=10.203.105.123:/tftpboot/ppc_root ip=on
 
Linux Boot sequence problem at:
ide: Assuming 50MHz system bus speed for PIO modes; override with
idebus=xx
NET4: Linux TCP/IP 1.0 for NET4.0
IP Protocols: ICMP, UDP, TCP, IGMP
IP: routing cache hash table of 512 buckets, 4Kbytes
TCP: Hash tables configured (established 1024 bind 2048)
Sending DHCP requests ...... timed out!
IP-Config: Retrying forever (NFS root)...

If bootargs is set as follows:
bootargs=root=/dev/nfs nfsroot=10.203.105.123:/tftpboot/ppc_root
ip=10.203.105.1
18:10.203.106.3:10.203.105.1:255.255.255.128:rattler:eth0:off

     host=rattler, domain=, nis-domain=(none),

The system is not able to get the DNS domain name properly. Can anybody
tell me why is this happening? When I switched on ETHEREAL I am able to
see a DHCP discover packet corresponding to my targets MAC address. Any
pointers would be highly appreciated.
 
With Regards,
