BBB - mounting rootfs from NFS

[Mahee]

Hello All,

I'm trying to mount root FS from my host PC's (Ubuntu) on BBB. After referring to various online references I was able to get to a point where BBB can detect my NFS share and goes all the way till Angstrom logo. When I try to log-in I get kernel panic.

Attached is log captured using UART. 

Any help would be greatly appreciated. 

Thanks,

Mahee

I am not familiar with how it is done on Ubuntu, but with Debian you need to allow connections to the NFS server. It seems the server is not responding because you do not have this setup correctly. However, as I said I am not too familiar with Ubuntu in this respect, so it is possible I am wrong.

So with Debian . . .

1) Install the NFS server and related packages.
2) sudo nano /etc/hosts.allow and add a line similar to ALL: LOCAL at the end of the file.
3) sudo nano /etc/exports and add a proper and existing export.

     Example:
     /home/username/rootfs xxx.xxx.xxx.xxx(rw,sync,no_root_squash,no_subtree_check)
    Where username is the normal user you’re logged into, and xxx.xxx.xxx.xxx is the static
    ipaddress you’re going to assign to your Beaglebone Black.
4) sudo exportfs -a
5) sudo nano /etc/default/services and add NFS=1 to the file ( This step may or may not be 
    depreciated ).
6) sudo service nfs-kernel-server start
7) sudo exportfs

Step 7 should give you a print out of all active / correct exports if everything was done correctly.

Again, all the above are necessary steps for setting up a "proper" export on Debian Wheezy. But all of the above are needed for an NFS share to be accessible outside of the server. I am almost 100% sure these steps verbatim will not work on Ubuntu, but there will be similar steps needed to achieve the same goal. Assuming exportfs is an actual NFS tool on Ubuntu, you most certainly can simply start by issuing the command on step 7 to test before going through the whole setup above.

Ah sorry I forgot to mention that you will need to make sure your uEnv.txt file is setup properly for NFS root as well. But as far as I can tell from the above output this seems to be the case already.

Also, I wrote an article on NFS root on my blog site, and talked with someoen who tested it with various distro's. This person told me that Angstrom, Fedora, and Ubuntu all had issues with these procedures. As I mentioned above the exact steps I listed above will probably not work, but serve as a rough guide as to what needs to be done. I suspect Angstrom uses a different services daemon ( system -v type init daemon ) which is the cause. SO you'll need to do some reading, and get a good understanding of the Angstrom distro in this aspect.

I can confirm that Ubuntu 13.10 uses the same setup.

FWIW, my uEnv.txt is below (I don't know how much of its formatting will survive google groups).

uenvcmd=run findfdt; if test $board_name = A335BNLT; then setenv mmcdev 1; mmc dev ${mmcdev}; if mmc rescan; then setenv mmc1 1; else setenv mmc1 0; fi; fi; setenv mmcdev 0; mmc dev ${mmcdev}; if mmc rescan; then setenv mmc0 1; else setenv mmc0 0; fi; if run loadtftp; then run nfsboot; fi;

#optargs=capemgr.disable_partno=BB-BONELT-HDMI,BB-BONELT-HDMIN capemgr.enable_partno=BB-SPIDEV0,BB-SPI1CLK

That's with the BBB as 192.168.1.17, and the server as 192.168.1.20.  The server is running NFS and TFTP servers (and an NTP server, come to that).
You _really_ need to use a serial/FTDI converter on tty0 while testing - it's the only way to find out what's going on.

Thanks William, John & Will.

I made a clean install of my VM and started from scratch. 

Instead of using Angstrom I used Ubuntu and now I'm able to use my rootfs from NFS server.

I'm still not sure what went wrong with Angstrom for now I'm happy for Ubuntu, will visit Angstrom again in a week or so. 

I will update my sequence on web in a day or so.
