RE: nfs boot problem

Wed, 05 Mar 2008 05:16:04 -0800

Hi,

 

I have tried using dhcp it didnt workout.

It keep on giving BOOTP broadcast messages.

so i tried doing in the following way it is giving kernel panic.

RPC: sendmsg returned error 101 is coming.

 

rpcinfo -p command shows portmapper, nfs,status,nlockmgr,mountd.

Hi Gopi,

Whoever mentioned the fact that you can't put variables into the kernel command line was correct (sorry I have deleted the e-mail so can't credit the person).

The minicom output is showing this as the kernel command line:

Kernel command line: console=ttyS0,115200n8 noinitrd rw ip=dhcp root=/dev/nfs nfsroot=$(nfshost):$(rootpath),nolock mem=116M

As you can see the $nfshost & $rootpath variables are not being expanded - you will have to hard code them. Still your problem seems to be DHCP related - the kernel should get an IP address but with the above command line it will then fail....as shown below - I put your command line into my DM355

Can you confirm that the ethernet interface actually works - can you download a file with tftp (having set an addres for 'ipaddr' and 'serverip' in u-boot)?
 
Can you try the 'dhcp' command in u-boot. For reference my board does this...
 
DM355 EVM # dhcp
BOOTP broadcast 1
DHCP client bound to address 172.18.128.166
TFTP from server 172.18.1.49; our IP address is 172.18.128.166
Filename 'uImage'.
Load address: 0x80700000
Loading: *
TFTP error: 'Only absolute filenames allowed' (2)
Starting again
The above tftp command fails because the DHCP server does not pass a filename (it has not been configured to do so) however it does get an address, which is to be expected. From the command output it would seem that the u-boot 'dhcp' command is using BOOTP rather than DHCP. From memory the 'standard' Linux DHCP server will not allow BOOTP requests by default - there is an option 'allow bootp' to turn this on.
 
You may need to speak to whoever manages the DHCP server on your network to confirn that BOOTP will work. If this is you then you are out of luck seeking advice ;-)
 
If you are relying on a ADSL router box (or similar) to do the DHCP server duty, you may need to consider switching to a dedicated Linux box. You can use the 'dnsmasq' package rather than the full DHCP server. This is a lot easier to set up although not as flexible as it is really there to do dynamic DNS for a local network - the DHCP functionality is secondary to this.
