    Hi Seven,

    What code are you using? Is this a ControlSUITE or c2000ware example, or custom code that you have developed?

    What HW are you using and what are you trying to communicate with (loop-back, UART on a different IC, a PC)? Have you scoped the SCI RX and TX pins to see if a signal is indeed being transmitted/received? If so, is the baud rate as expected?
