Serial Port Problems about MSP430F5529

Other Parts Discussed in Thread: MSP430F5529

Good morning,sir

I met some troubles about MSP430F5529 under the non-debug mode.

Question 1: The serial can send characters as normal under the debug mode of CCSV7 as the following picture:

                                                                                                 

The test variables are the sending characters. The value belongs to SMCLK.But it can’t send characters normally after closing debug mode as the picture 2 shows.

                                                                                                

I change the serial port assistant baud rate under the non-debug mode while at the same time showing them by hexadecimal, and it can send the character ‘A’ as normal. The board reset is unable to solve the problems. I also have tried other seriel port to solve such a trouble,but It’s not helpful.My code is give below.

                                                                            

I am a newbie in learning MSP430, so I can’t use the clock configuration. And I set the baud rate according to the datasheet of MSP430F5529 . Can you tell me what problems occurred in the serial port?

Thanks.
