LAUNCHXL-F280049C: Board Error, how to fix?

Part Number: LAUNCHXL-F280049C

I just bought a Launchxl-F280049c last week, and I am trying to run an example program to send data to a raspberry pi computer. Here is my connections:

Launchxl: Pin44 SCIATX to Raspberry pi's Pin10 

Launchxl: Pin43 SCIARX to Raspberry pi's Pin8

Launchxl: Pin62 GND to Raspberry pi's Pin6.

I am new to Ti C2000, Please give me some advice on how to use this board, and how to fix this problem. 

Thanks.
