Hi, 

I have a trouble to boot in NFS a linux 4.9.166 on an IMX6Q, it hangs forever after this following lines :

[12.193345] Sending DHCP requests ., OK
[ 12.273188] IP-Config: Got DHCP answer from 192.168.1.1, my address is 192.168.1.194
[ 12.281050] IP-Config: Complete:
[ 12.284435] device=eth0, hwaddr=00:14:2d:49:e7:09, ipaddr=192.168.1.194, mask=255.255.255.0, gw=192.168.1.1
[ 12.294783] host=192.168.1.194, domain=imajing, nis-domain=(none)
[ 12.301425] bootserver=0.0.0.0, rootserver=192.168.1.211, rootpath= nameserver0=192.168.1.1

The configuration that I use work with a linux 3.14.52, I have done few changements to work with the new kernel version but the nfs part is still the same. Do I miss settings to add to the configuration ? 

Thanks

I found the problem, it was the uart configuraiton that was wrong, I have still problems but it is no longer concerning this issue. 

I'll close the discussion, thank you for your help Shivani Patel.

Hi, Alexis Fronteau

Please refer this document to boot the board over NFS.

I have tried the Linux kernel 4.9.166 from this link and was able to boot the board over NFS.

Let me know if you are still facing the error with the above information.

Kindly share your steps to setup the NFS and error logs as well.

Hope this information will be useful to you.

Regards,

Shivani

Hi, thanks for your reply.

In fact, I am building my own kernel with buildroot with based on the apalis-imx6q defconfig. I was able to connect to my board in tftp/nfs when I used linux 3.14.52 (that I also built on my own with buildroot). So, I don't think the problem is on the server part of the nfs connection. The boot of the card processor give me that :

I found the problem, it was the uart configuraiton that was wrong, I have still problems but it is no longer concerning this issue. 

I'll close the discussion, thank you for your help Shivani Patel.
