Hello Sai.,

If the command returns -sh: setenv: command not found your are in Linux, not in U-Boot. Please stop the device in U-Boot stage and enter the command there.

Best regards,
Kemal

Dear Sai,
It seems to be you have not connected the USB cable for getting the console messages.
Please connect the USB cable on J3 port (USB- UART) to see the console messages, there you will get the u-boot and Linux shell prompt as Kemal said.

Able to see the new COM port after you connected the USB cable from LCDK board to PC ?
Use windows' device manager to detect the USB port no, COMx
After the COM port detected, you need to open the port through any terminals in PC, like tera term or hyper terminal.
In linux, you can use minicom.
