DM355:NFS boot trouble

try adding serverip to your u-boot bootargs

   > setenv serverip 192.168.10.10

and see if that helps.  Optionally, you can try using a router (buy al local electronics store) in between your Host and EVM to connect (if you suspect a dhcp server issue).  Or even use static IPs (no dhcp server needed) to boot.

Normally, if you can ping, you have firewall on host disabled (iptables) and you have exported (/etc/exports per GSG) the directory you are trying to NFS mount, you should be good to go.

Hi Juan,

No way.

I've tried what you suggested setting serverip to 192.168.10.10, stopping dhcp service on the host pc,assigning static ip address (but I don't know if bootarg syntax is correct).

printenv result is:

bootdelay=3

baudrate=115200

nfshost=192.168.10.1

rootpath=/home/ns/workdir/filesys

bootcmd=nboot 0x80700000 0 0x400000;bootm

bootfile="uImage"

serverip=192.168.10.10

ipaddr=192.168.10.11

bootargs=console=ttyS0,115200n8 noinitrd rw ip=192.168.10.11 root=/dev/nfs nfsroot=192.168.10.10:/home/ns/workdir/filesys,nolock mem=116m

stdin=serial

stdout=serial

stderr=serial

videostd=pal

Unfortunately booting the board I saw:

gw and bootserver look strange to me but I really don't know...

Thx, Simone

I should have been more specific, I did not meant you should first try to set serverip; only if this did not fix the problem consider the other two options (off-the-shelf router or static-ips).

If you want to try the static ip option, see http://focus.ti.com/general/docs/litabsmultiplefilelist.tsp?literatureNumber=spraaq0

have you made sure your host firewall is disabled and /etc/exports is set per Getting Started Guide.

Hello Juan,

now I'm in this situation:

Host has a static IP (192.168.10.10)

DVEVM has a static IP (192.168.10.11)

connected directly with a cross-cable(also tried a a straight cable)

I've set the env var follwinf the pdf you suggested.

printenv output is:

bootdelay=3
baudrate=115200

Re-booting I have the same problems as yesterday.

UFW is disabled so no firewall is running.

I've lauched Wireshark and I got the following log:

Actually don't know what to do now. I'm wasting a lot of time and up to now I can't even switch on or off a led....really disappointing.

Thanks for your help,

Simone

This may be an obvious statement, but do you have the NFS server running on your laptop which is running ubuntu as well as the target filesystem directory exported via the /etc/exports file?

In the discussion above, there was mention of shutting down the firewall, which you indicated you have.  DHCP is clearly running because you were able to get the proper IP address.

I would look to make sure the NFS server is operational.

Finally I got it.

Following BrandonAzbell suggestion I just did not consider the 'Getting started guide'  and searched on Ubuntu forums.

This link https://help.ubuntu.com/community/NFSv4Howto solved my problems.

Now I've some other troubles (actually too much for an evaluation product!) but I'll post them in another thread.

Thanks everybody,
