Serial Debugging

Hi

Im new at embedded linux and android. Im trying to develop an android tv platform. So bear my questions.

Okay can anyone brief me about the serial debugging function of the Reload board. I already connected the serial port with the usb of my system and when i start up the device i can see the bootup message and see processes running even after the bootup. And when I connect with the serial port after booting up i can enter the shell command line. So I am just wondering what is the actual use of this? If someone can just give an example of the debugging n relation to my project.
