NFS Boot Problems

Rafael,

in order to best help you, we need more information.  Please walk us through every step that you performed while following the directions to install the software and share the corresponding output once you execute a particular command in the instructions.  Thanks.  We need to get a known good install on your system before we can start guessing as to what might be wrong.

Looks like your NFS server isn't configured correctly.

John A

Also, can you share your bootargs so we can see how you are configuring your NFS setup?

Hi,

Until now i was able to use the dvsdk 1.4, using the same TFTP + NFS filesystem mounting idea but using CentOS instead of Ubuntu.

Here is a more detailed steps that a took to dvsdk 3.10:

1. I could successfully install tftpd-hpa and load the kernel image (uImage) from a host (which we can see in the complete boot log below);

2. I stopped the ubuntu ufw firewall:

     a. [host]$ service ufw stop

         [host]$ ufw stop/waiting

3. I installed the nfs server (nfs-kernel-server) and:

    a. Edited the /etc/exports file and add the line: "/home/rmadeira/workdir/filesys *(rw,no_root_squash,no_all_squash,sync,no_subtree_check)"

    b. Restarted nfs server:

        [host]$ /etc/init.d/nfs-kernel-server restart

            and got de output:

           * Stopping NFS kernel daemon                                    [ OK ] 

           * Unexporting directories for NFS kernel daemon...   [ OK ] 

           * Exporting directories for NFS kernel daemon...       [ OK ] 

           * Starting NFS kernel daemon                                     [ OK ]

4. Then i installed all the packages needed for dvsdk (dvsdk installer 3.10, codec servers, linux bin utils, etc,etc..)

5. I successfully create uImage file (executing [host]$ make  linux) as compiled the dvsdk 3.10 package ([host]$ make  && make install ) without erros. This steps are described at http://processors.wiki.ti.com/index.php/GSG:_DVEVM_Software_Setup_for_DM6467_Platforms

6. At the board side, my environment variables are as follow:

I guessed too that NFS might be not well configurated, mainly because i can't find why the nfs is trying to mount  /tftpboot/10.0.0.25 neither why it is using the gettway 10.0.0.1 (my office network router address).

I you need more infos, please tell me.

Tanks,

Jonh,

at some moment i misspell nfsroot by nfshost. I returned to the correct values, but the final output didn't change. I believe this is because 'bootargs' is correctly set.

Rafael Madeira

Make sure you can mount the file system from a computer to ensure you have the server configured correctly.
