DM6467 EVM Bootup - Root-NFS: Unable to get nfsd port number from server, using default

This sounds like maybe your NFS service on the host is not enabled (see section 4.3.5 of GSG).  Actually, after analyzing the log a bit more, the ip addresses do not make much sense to me

   TFTP from server 172.22.192.2; our IP address is 172.22.1.100; sending through gateway 172.22.0.1

suggests you loaded you Linux kernel via TFTP and your host address is 172.22.192.2; but the following bootlog line

   Kernel command line: console=ttyS0,115200n8 noinitrd rw ip=172.22.1.100:172.22.1.217::255.255.252.0:dm6467:eth0: root=/dev/nfs nfsroot=172.22.1.217:/home/mindtree/workdir/filesys,nolock mem=120M davincihd_capture.channel0_numbuffers=4

suggests you are using static IP of 172.22.1.217 for your Linux host; unless you are using two distinct linux host PCs (not sure why you would want to), I would expect same host IP address.

Thank you very much Juan for the input.

I will try that change..and see that EVM boots properly..

Hi Juan,

My host ip is 172.22.1.217...

Hi pradeep.

Try this:

setenv bootargs console=ttyS0,115200n8 noinitrd rw ip=172.22.1.100:172.22.1.217::255.255.252.0:dm6467:eth0: root=/dev/nfs nfsroot=$(nfshost):$(rootpath),nolock,tcp mem=120M davincihd_capture.channel0_numbuffers=4

After adding the tcp flag, it worked on my machine.

After re-installing my NFS it started working...I got rid of the error.

Thanks for the support...

Hello I am facing problem in booting DM6467 EVM ..

Currently I m following GSGuide for TMS320DM6467 and want to Test the shared file System(chapter 4.3.6 of GSG).

I want to Boot from Flash Using NFS file system and for that when I set my boot arguments as mentioned in Section 4.3.6 GSG Appendix A3.3 ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

setenv bootargs console=ttyS0,115200n8 noinitrd rw ip=dhcp root=/de v/nfs nfsroot=$(nfshost):$(rootpath),nolock mem=120M davincihd_capture.channel0_ numbuffers=4 ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

I am getting following errors in boot process: . . . Sending DHCP Request.....time out!

In order to solve this ,I used static Ip approach and my new environment variables are: --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

setenv bootargs console=ttyS0,115200n8 noinitrd rw ip=10.3.28.60:10 .3.28.40:10.3.28.1:255.255.255.0::off root=/dev/nfs nfsroot=10.3.28.40:/home/bil al/workdir/filesys, nolock mem=120M davincihd_capture.channel0_numbuffers=4 --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Now another error of Kernel Panic is coming in boot process and again I am unable to boot from NFS . :

Can some one please help me?

Hello,

in my recent post, i mentioned the problem faced in boot process of DM6467.

By changing my environment variables again to ip= dhcp  , and using root=/dev/hda1 boot process is

running now. But this is not helping me in mounting my host directory filesys to target board as i am booting

from EVM hard drive filesystem instead of NFS file system.

So, Can someone please suggest me how to work with root=/dev/nfs in dm6467 boot process ,as uptil now

i am getting kernel panic error whenever i set root=/dev/nfs in bootargs ...

( Note: there is no /nfs folder in  /dev folder ,either in Board linux or host linux filesystem and i am getting

' No such file or directory ' when i tried cd /dev/nfs .If that is the reason behind kernel panic error then please

let me know how to fix it ..)

Thanks,

Bilal

Hi,

You should set the path to nfsroot as well as review the /etc/exports on your host

Example for bootargs as follows: root=/dev/nfs nfsroot=192.168.10.1:/path/to/rootfs

According to above example the /etc/exports/  file should contain /path/to/nfsroot *(rw,insecure,no_root_squash,no_all_squash,sync)

Prior booting the target, do not forget to restart the server [/etc/init.d/nfs restart]

Use nfsstat to check server statistics, you may refer to http://nfs.sourceforge.net/nfs-howto/ar01s05.html for performance optimization.

Regards,

Michael Sasson

Hello,

Thanks for the reply Michael. Although I'm already using the same method but I will try  this 

again and let you know the results afterward.
