How to assign the valid ip address to the board in the U-boot?

I have connected the board to the linux laptop which doesn't the dhcp server running in it. I want to assign the static ip address to the board ie 192.168.1.3.

Assign below the ip=192.168.1.3 and removed the dhcp from the below line but the IP is not set in the u-boot.

/home/uic68347/ti-processor-sdk-linux-j7-evm-08_00_00_08/bin/setupBoard.minicom

expect {
"=>"
}
send "setenv init_net 'run args_all args_net; setenv autoload no; dhcp'"

send "setenv args_net 'setenv bootargs console=${console} ${optargs} rootfstype=nfs root=/dev/nfs rw nfsroot=${serverip}:${nfs_root},${nfs_options} ip=dhcp'"

expect {
"=>"
}

expect {
"=>"
}
send "setenv setup_net 'setenv autoload no; dhcp'"

expect {
"=>"
}

Regards,

    Hi,

    Which port do you want to assign IP to ? Is it the MCU CPSW port ?

    Can you use the mii command to show the link status as well ? Please also confirm that you are using the EVM

    Regards

    Hi ,
    I have set the ip address in the u-boot command prompt, i was able to load the rootfs. let me where to make the changes in the script.sh so that it can boot directly.

    U-Boot # setenv ipaddr 192.168.1.2 U-Boot # setenv serverip 192.168.1.1 U-Boot # setenv gatewayip 192.168.1.1 U-Boot # setenv netmask 255.255.255.0

    U-Boot # boot

    Able to load the rootfs.

    but when i make the changes in the 
    nfsroot=${serverip}:${nfs_root},${nfs_options} ip=dhcp'"
    send "setenv setup_net 'setenv autoload no; dhcp'"

    Not working.

    Let me know if you have any update for me on the changes needed for the script.sh?

    Regards,

    Viswa

    Hi Viswanathan,

    Sorry for the late reply.

    Have you saved these changes using a saveenv command?

    Please try that once.

    Also the "bin/setupBoard.minicom" script is having formattion issue while seen in the post. Please add an '.txt' extension to the file and upload the file as attachment.
