Hi, Dhanasekar, I see "console=tty0 console=ttyUSB0,115200n8" in your configuration.
You might want to check if "ttyUSB0" matches what Linux kernel denotes your serial port. I am not expert in Linux kernel so not exactly sure how to debug this. A possible way may be trying to enable Linux serial output on a known good BIOS with your board (if there is such a BIOS) first.
