The debug board is described here. http://support.logicpd.com/downloads/1165/ This is a wiki showing the debug board in use https://omapzoom.org/gf/project/omapzoom/wiki/?pagename=GettingStartedWithZoomII_AKA_OMAP34XII_MDP The zoom2 has an auxillary board that contains the serial, net, jtag and battery simulator. This change supports a runtime check if the debug board is connected.

The default serial is from the USB connector on left side of the debug board. The USB connector will produce 2 of the 4 UARTS. On your host pick the first enumeration. The serial port set up is the same with Zoom1. Baud rate 115200, 8 bit data, no parity, 1 stop bit, no flow.
