On the Devboard there is an FTDI chip handling the debug port.. Not sure if GTA04 went with that exact chip or not with the Pyra. 


From the OMAP5 EVM Manual:


2.9 Debug UART Interface


The OMAP5432 EVM provides a dual-port USART device (FTDI part number FT2232HQ). This provides


up to two UART terminal interfaces out via a single USBOTG micro-AB connector located at J14. Driver


software to utilize this device must be downloaded from the FTDI website. The first (lowest numbered)


port of this device is connected to UART3 from the OMAP5432 ES2.0 processor, while the second port is


unused. There are voltage translators provided to convert the 1.8V logic level UART signals to/from


OMAP5432 ES2.0 to the 3.3V signals required by the USART.
