TMS320F28069: SCIA not receiving any data in SCIRXBuffer. Using the LaunchXL red board.

I believe I have configured all the necessary registers to receive UART data on SCIA port. I have verified that data is presented to the hardware pin which in this case is pin 7 for RX. Attached are few screen shots of SCI and GPIO registers from microcontroller. SCIA TX works just fine on pin 12.

    Hi Prasoon,

    Have you ran one of our examples within C2000Ware (for SCI)? If the example works fine, then this can help rule out any issues with hardware and we can look into your software more closely. 

    What data are you receiving? I do see content in your SCIRXBUF register. It would be very helpful to see your initialization code and how you are reading RX data more than the register configuration. 

    Best Regards,
