    Hi Ivan,

    Yes, possible, you can boot the board with static IP address and server address for NFS booting ie one to one

    setenv ipaddr 10.100.1.1

    setenv serverip 10.100.1.2

    Connect the ethernet cable board to PC and set serverip (10.100.1.2)  as IP in PC network connection.

    Hi Ivan,

    What kind of boot method are you trying ie NFS or MMC or NAND ?

    Could you attach your uEnv.txt file ?

    Hi Stalin:

                              it seems to not work. I use "ifconfig", the ip address didn't change.

    Need to modify the "bootargs" to get the IP address to linux.

    mmcargs=setenv bootargs console=tty0 console=${console} ${optargs} ${kms_force_mode} ip=$ipaddr root=${mmcroot} rootfstype=${mmcrootfstype} ${systemd}
