Change debug port from UART0 to USB0 in Beaglebone Black

Currently I am working for Bare-metal Programming on Beagle Bone Black Board. I gone through the BBB booting procedure and I found that the boot environment using UART0 as debug/console. Now, I want to change debug port from UART0 to USB0 .

  1. Is it fixed in Boot ROM code only.?
  2. What are all the necessary information should I know.?
  3. Is it required to modify in u-boot source code.? if yes, where can I change.?

Please respond as soon as possible.

Thanks and Regards,
