NFS Help -- No Ethernet?

Hi,

>>portmap: server 192.168.0.50 not responding, timed out

The Portmap operation where the timeout is happening is contacting the portmap daemon on your Linux IP.

Have you checked, that it is running? You can use "rpcinfo -p " to check it. 

Also, are you running the nfs daemon on your Linux host. Try exportfs -a and check if you see the directory with fs exported.

Can you mount the nfs filesystem from other computers? You may have to export it to them, but that may be easier to debug, because you can enter commands on them...

Do you have any kind of firewall on your Linux Host. If yes, disable i and test.

>>also, Maybe this is easier somehow if I can boot to a local filesystem stored in NAND? Anyone know how I might go about doing that?

Hi Gururaja,

Yes, portmap looks good on host. did export of the file system. NFS is running, firewall is off. I can mount the fs as well on a computer. The thing that I really notice is that I don't see the EVM even trying to get to the NFS. I do a wireshark capture, but don't see the EVM even trying to do anything across the network after TFTP the uImage. I added the rootdelay in an attempt to possibly fix this, but that did not. It really just seems like the Ethernet does not get a link after the TFTP process. Any thoughts or options to compile the kernel with to maybe see more of what is happening?

Thanks

Tim

Hi,

Can you boot the boot using non-nfs mode & then ping the linux host to see if the connection is fine. Also once in linux console, try to mount the nfs filesystem through "mount -t nfs" option.

Regards

Gururaja

Hi Gururaja,

I am using this EVM: http://focus.ti.com/dsp/docs/thirdparty/catalog/devtoolsproductfolder.tsp?actionPerformed=productFolder&productId=8017

So there is no hard drive. I will need to follow your steps to building and putting into NAND before I can try regular boot process. I will give this a try and then post back. If you can think of anything else that might be wrong....

I have made it a little further, but maybe someone has seen this happen and can help the rest of the way. Now TFTP and NFS are on the same server 192.168.0.50. Thanks.

Hi,

I have seen such errors cause for which was IP address conflict. Can you check whether the IP 192.168.0.100 is assigned for anyone else?

Regards, Sudhakar

Rajashekhara,

I dont think there is a conflict. The only devices on the network are my EVM, my computer, and the switch that ties them together. I can change the IP address and see if that helps. I wouldn't suspect it though. Thanks for the help!

Tim

Rajashekhara,

Changing the IP did not fix the problem.... any other thoughts?

Thanks

Searched about in this forum. A few hits:

- Duplicate IP address. You've already checked that.
- Duplicate MAC. Doubtful
- Incompatible gigabit switch. Switch to 10/100.
- Net config in targets rootfs /etc/network/interfaces is different than bootargs.

Seems to be a lot of failure modes with NFS.

Anyone else out there have any thoughts? Maybe someone from TI can shed some light on this?

Firewall is stopped

NFS is running and can mount the drive locally

File system is exported correctly

Seems that it mounts 2 times and on the second just stops after "Calculating module dependencies"

Wireshark capture does not seem to show any "errors"

filesystem has root ownership. root built file system.

Data still being send from EVM to Host, but shows IP fragment not NFS.

Tried Arago pre-built. root tar to directory, export directory. Same issue.

Modified /etc/network/interfaces with

auto eth0

iface eth0 inet static and dhcp. Bot no go.

DHCP gets and sets IP adderss to 192.168.0.100 (did this last night)

Seems like after 2nd boot that the Linux Ethernet driver kicks in and looses the NFS for some reason?

Been working on this for 2 weeks. Need some help or a work around to get going. Can I TFTP the filesystem using U-boot to flash and then run from there? How can I do this?

Thanks

Tim

Looks like not much more to try. Maybe try a slower 10/100 switch/router. Some notes here:

http://processors.wiki.ti.com/index.php/UG:_DaVinci_PSP_Installation_on_DM644x_EVM

You can try this interactively from U-Boot without making permanent changes:

tftp 0x80700000 uImage
tftp 0x82000000 arago-base-image-arago.ext2.gz
setenv bootargs video=davincifb:vid0=0,2500K:vid1=0,2500K:osd0=720x576x16,2025K davinci_enc_mngr.ch0_output=COMPOSITE davinci_enc_mngr.ch0_mode=ntsc console=ttyS0,115200n8 rw ip=192.168.0.100:192.168.0.52:192.168.0.1:255.255.255.0:::off eth=00:0e:99:02:51:54 root=/dev/ram0 rw initrd=0x82000000,4M mem=118M
boot

The above should allow the kernel to boot with a RAMDISK. Once up, you should be able to poke around to see why the network is not working. Note that any changes to the RAMDISK are lost on reset.

EDIT: Oops. Removed noiinitrd from bootargs.

ok making some progress here....

in module-init-tools I comment out:

local RET ERROR=
    local action=$1
    local actionName=
   
    case "$action" in
        "load")
