CC3200定时器无法进入中断

程序是自己参考timer demo写的，经过UART调试发现，定时器中断没有进入，对比了timer demo，也没发现错误，请问问题出在哪里？以下是代码：

void TimerBaseIntHandler(void)
{
 printf("int_1\r\n");
// unsigned long ulInts;
// ulInts=MAP_TimerIntStatus(TIMERA0_BASE, true);
// MAP_TimerIntClear(TIMERA0_BASE,ulInts);
// MAP_TimerIntClear(TIMERA0_BASE,TIMER_TIMA_TIMEOUT);
 Timer_IF_InterruptClear(TIMERA0_BASE);
 TimerOutCont++;
 printf("int\r\n");
}
int main(void) {
 
// unsigned int SensorValue=0;
 BoardInit();
 PinMuxConfig();
 UART_Init(115200);
 printf("begin\r\n");
 //TIMER_Init();

 Timer_IF_Init(PRCM_TIMERA0, TIMERA0_BASE, TIMER_CFG_PERIODIC, TIMER_A, 79);
 Timer_IF_IntSetup(TIMERA0_BASE, TIMER_A, TimerBaseIntHandler);
 Timer_IF_Start(TIMERA0_BASE, TIMER_A, 0xffff);

 while(1)
 {
  printf("end\r\n");
//  Sensor_Start();
//  SensorValue=Sensor_GetValue();
//  sprintf((char *)string,"%d\r\n",TimerOutCont);

 }
}
void BoardInit(void)
{
 MAP_IntVTableBaseSet((unsigned long)g_pfnVectors[0]);
 MAP_IntMasterEnable();
 MAP_IntEnable(FAULT_SYSTICK);
 PRCMCC3200MCUInit();
}
void UART_Init(unsigned int boand)
{
 MAP_UARTFlowControlSet(UARTA0_BASE,UART_FLOWCONTROL_NONE);
 MAP_UARTConfigSetExpClk(UARTA0_BASE,MAP_PRCMPeripheralClockGet(UARTA0_BASE),boand, \
   UART_CONFIG_WLEN_8|UART_CONFIG_STOP_ONE|UART_CONFIG_PAR_NONE);
}
void UART_StringPuts(unsigned char *str)
{
 if(str!=NULL)
 {
  while(*str!='\0')
  {
   MAP_UARTCharPut(UARTA0_BASE,*(str++));
   while(MAP_UARTBusy(UARTA0_BASE));
  }
 }
}
int fputc(int ch,FILE *f)
{
 MAP_UARTCharPut(UARTA0_BASE,(unsigned char)ch);
 while(MAP_UARTBusy(UARTA0_BASE));
 return(ch);
}

更改了Timer_IF_Init(PRCM_TIMERA0, TIMERA0_BASE, TIMER_CFG_A_PERIODIC|TIMER_CFG_SPLIT_PAIR, TIMER_A, 79);后还是不可以！

问题已经解决！定时器不能进入中断，是中断向量表的问题！
修改上面的错误地方：MAP_IntVTableBaseSet((unsigned long)g_pfnVectors[0]);
为：
     MAP_IntVTableBaseSet((unsigned long)&g_pfnVectors[0]);
‘&’符号没有打上~！

问题已经解决！向量表初始化出错。

更改：

MAP_IntVTableBaseSet((unsigned long)g_pfnVectors[0]);

为：

MAP_IntVTableBaseSet((unsigned long)&g_pfnVectors[0]);

缺少‘&’号！
