Reply To: MTUDK2-ST-CELL board

Hi Toyo,
When plugging into the micro USB connector, you gain access to two serial ports. Pins 9 & 32 go through the USB-UART converter. Pins 1 & 40 go through the interface chip.
The USB pins on the 40 pin connector and not routed to anything on the UDK board. They are connected in parallel with the micro USB connector on the MTQ.
