Perform the following steps in case console is not showing any print:
1. Ensure that USB-to-UART bridge VCP driver is installed correctly on the host computer.
2. Ensure that the DIP switch has default settings, it means, SW1[1:10] = 0010001000.
3. Ensure that the power adapter is connected properly to the board power jack and external power supply.
4. Ensure that the cable making console connection is properly connected as mentioned in
