I remember the actual debug pads being on the bottom side of the board 
on the right side of the SoC (i.e., right of the green rectangle on your 
picture). If you go that way, someone @nvidia.com can probably look up 
the UART pads for you. However, another way (that I used briefly) is to 
grab one of these:

and with some pinmux editing get a 3V3 serial port out of the microSD slot.

Cheers,
Mikko
