    Hi Akash,

    https://www.tecmint.com/install-nfs-server-on-ubuntu/

    Check if the nfs server is installed correctly on your host ubuntu.

    Also is tftp setup on your host PC?

    Can you try the below from U-Boot prompt:

    tftp 0x82000000 Image; tftp 0x81200000 k3-j721e-common-proc-board.dtb

    Best Regards,

    Hello,

    I tried tftp setup on PC and tftp folder was set to /var/lib/tftpboot and while setup it was setup to /tftpboot

    i changed the directory to /tftpboot still the issue persists

    Hi Akash,

    I see that you are using the 8.0 SDK

    Akash Patil said:

    Which ethernet port are you using for tftpboot? The single port J35 alone can be used from U-Boot. U-Boot has support for CPSW2G.
    Can you confirm that?

    Hi Akash,

    In the $PSDK path you a script 'setup.sh'. Have you run that & setup the nfs & tftp?

    Hi Akash,

    Apologies for the long delay in responding. I had migrated to 8.1 SDK. I have now installed
    8.0 SDK. I have installed tftp server in /tftpboot directory of my host.

    I have the 8.0 U-boot binaries in the boot partition of my SD card.

    I am able to use tftp on 8.0 Successfully.

    Also recommend having the IP Address of the EVM & PC on the same subnet mask.
    Basically ping should work from U-boot prompt. ping from your EVM to PC(host) should work.
