That board uses the 56-pin package, which does not have any UARTs. You can easily make a fast (115200) send-only software UART for debugging:

Note that this code assumes there will be no interrupts during the execution of usartSendByte(); if your firmware uses interrupts you'll need to disable them on entry and re-enable them on exit.
