u-boot NFS problem

[il_mix]

Hi everyone,

I have a SABRE IMX6Q, that was correctly working with NFS.

Now I messed up the u-boot parameters, and I'm not able to let it work again.

Here is the output of the 'pr' command in u-boot

baudrate=115200

boot_fdt=try

bootargs=console=ttymxc0,115200 root=/dev/nfs ip=10.0.10.216:10.0.10.108:10.0.10.1:255.255.255.0:sabresd:eth0:off:nfsroot=${serverip}:{nfsroot},v3,tcp

Environment size: 2098/8188 bytes

uBoot isn't able to locate uImage.

uImage is copied in my tftp directory, the one listed in /etc/default/atftpd.

Then, the fyle system is in nfsroot=/home/cristofolini/tftp, and the directory is exported in /etc/exports

Am I missing something?

Thanks for the support!

Hi Massimo,

Would you please try copy the uImage to your /home/cristofolini/tftp directory, as you have set nfsroot=/home/cristofolini/tftp .

Hope this can help you ~~

Best Regards

Hi Dan,

I've tested the device on another PC where it previously worked, and NFS is still working. So u-boot configuration is ok; the problem is in TFTP/NFS configuration on PC side.

Thanks

Hi Massimo,

My pleasure:smileyhappy:.  The TFTP/NFS configuration you can reference the document "Setting_Up_LTIB_host.pdf". Any questions contract with me easily~~

Best Regards

Dan
