CCS/MSP430F5529: About using the SPI interface

Tool/software: Code Composer Studio

Hi, I am new to msp430 and now I have a problem using msp430 SPI interface.

I want to test the SPI interface, but after I connect the logic analyzer with msp, the SPI signal was not sent out. the CLK and MOSI stay low all the time. I am wondering if it is the problem with the board. if yes, how can I test it. I actually tried the sample code of SPI provided by TI, but it doesn't work either.

Following is my code. it will repeatedly send 0x00 and 0xc8. 

#include "driverlib.h"
#define SPICLK                          1000000

uint8_t returnValue = 0x00;
void SendCodeSPI(uint8_t data);
void main (void)
{
    WDT_A_hold(WDT_A_BASE);
    //__enable_interrupt();
    //Set P1.1 for slave reset
    /*GPIO_setAsOutputPin(
                GPIO_PORT_P1,
                GPIO_PIN2
                );*/
    GPIO_setAsOutputPin(
                    GPIO_PORT_P1,
                    GPIO_PIN3
                    );
        //P3.5,4,0 option select
        GPIO_setAsPeripheralModuleFunctionInputPin(
            GPIO_PORT_P3,
            GPIO_PIN0+GPIO_PIN2
            );

        //Initialize Master
        USCI_B_SPI_initMasterParam param = {0};
        param.selectClockSource = USCI_B_SPI_CLOCKSOURCE_ACLK;
        param.clockSourceFrequency = UCS_getACLK();
        param.desiredSpiClock = SPICLK;
        param.msbFirst = USCI_B_SPI_MSB_FIRST;
        param.clockPhase = USCI_B_SPI_PHASE_DATA_CAPTURED_ONFIRST_CHANGED_ON_NEXT;
        param.clockPolarity = USCI_B_SPI_CLOCKPOLARITY_INACTIVITY_LOW;
        returnValue =  USCI_B_SPI_initMaster(USCI_B0_BASE, &param);

        if (STATUS_FAIL == returnValue){
            return;
        }

        //Enable SPI module
        /*GPIO_setOutputHighOnPin(

        USCI_B_SPI_enable(USCI_B0_BASE);

        //Wait for slave to initialize

        GPIO_setOutputHighOnPin(
                                    GPIO_PORT_P1,
                                    GPIO_PIN3
                                    );
        while(1){
            USCI_B_SPI_transmitData(USCI_B0_BASE, 0x00);
