Hello,

Could you please attach a full boot log (.txt file) to a post. We need to see what is going on outside of the screen captures you have provided. Thank you.

Thank your reply.

Hi, thanks that is easier to read. 

You didn't provide the U-boot part, which would be useful. It looks like somehow the kernel command line, which is set by U-Boot environment, is not correct

han hosung said:

[ 0.000000] Kernel command line: console=ttyO0,115200n8 root=/dev/nfs nfsroot=10.20.11.7:/home/selpman/am335x-evm-06.01.00.08/targetNFS,nolock rw=10.20.11.56

the "rw=..." should be ip=10.20....

I'm not sure if this is the only problem or why this happens. We provide a setup.sh in the SDK root directory that you can consult to see how we set up and verify NFS. Maybe that will provide some insight for you.

Thanks.

my U-Boot set is here:

setenv nfsopts nolock,v3,tcp,rsize=4096,wsize=4096

setenv ipaddr 10.20.11.56   (device ip)

setenv serverip 10.20.11.7  (server ip)

setenv rootpath /home/selpman/am335x-evm-06.01.00.08/targetNFS

setenv fdtfile am335x-boneblack.dtb

setenv netloadimage nfs ${loadaddr} ${serverip}:${rootpath}/boot/${bootfile}

setenv netargs setenv bootargs console=ttyO0,115200n8 root=/dev/nfs nfsroot=${serverip}:${rootpath},${nfsopts} rw ip={ipaddr}

setenv netloadfdt nfs ${fdtaddr} ${serverip}:${rootpath}/boot/${fdtfile}

And i tried as below :

ping 10.20.11.7 -> ping Check with Server okay

run netloadimage / netloadfdt -> download okay

run netargs -> check with printenv okay

So, is there anything wrong with netargs?  Or NFS settings on the host?

Please, could you give me directions to solve the problem?

Thanks.

Hello,

Please see this thread:

https://e2e.ti.com/support/processors/f/791/t/841572?AM5728-NFS-boot-issue

Can you check your NFS version and make sure version 3 is enabled? It might be interesting to try the full nfsvers=3 instead of just v3.

Also, it might be good to try a full IP address spec, per the thread, for your static IP as well.

I can't tell from the wireshark capture picture that you posted, but are you seeing activity after the dtb/kernel are transferred? What does that look like?

Thanks.
