S32K144 定时器中断不进中断？

各位好！
   最近正在用蓝宙的S32K144开发板，用的S32DS开发环境，仿真器J-Link。设置了一个定时器中断遇到一点问题，请教给位高手！
   用PE配置的overflow定时器，Debug的时候发现，定时器已经循环计数，中断标志也置起了，但是程序不进中断服务函数。
   下面是代码，前一段是main，后一段是中断服务函数。
int main(void)
{
       ftm_state_t ftmStateStruct;

  /*** Processor Expert internal initialization. DON'T REMOVE THIS CODE!!! ***/
  #ifdef PEX_RTOS_INIT
PEX_RTOS_INIT();                /* Initialization of the selected RTOS. Macro is defined by the RTOS component. */
  #endif
  /*** End of Processor Expert internal initialization.                   ***/

  /* Write your code here */
  CLOCK_SYS_Init(g_clockManConfigsArr, CLOCK_MANAGER_CONFIG_CNT, g_clockManCallbacksArr,
   CLOCK_MANAGER_CALLBACK_CNT);
  CLOCK_SYS_UpdateConfiguration(0U, CLOCK_MANAGER_POLICY_AGREEMENT);

  PINS_DRV_Init(NUM_OF_CONFIGURED_PINS, g_pin_mux_InitConfigArr);
  GPIO_HAL_SetPinsDirection(PTB,((1 << 4U)|(1 << 5U)));

  FTM_DRV_Init(INST_FLEXTIMER1, &flexTimer1_InitConfig, &ftmStateStruct);

  INT_SYS_InstallHandler(FTM0_Ovf_Reload_IRQn, &ftmTimerISR, (isr_t*) 0);
  INT_SYS_EnableIRQ(FTM0_Ovf_Reload_IRQn);

  FTM_DRV_InitCounter(INST_FLEXTIMER1, &flexTimer1_TimerConfig);
  FTM_DRV_CounterStart(INST_FLEXTIMER1);

  GPIO_HAL_SetPins(PTB,(1 << 4U));
  GPIO_HAL_ClearPins(PTB,(1 << 5U));

  while(1)
  {

  }

  /*** Don't write any code pass this line, or it will be deleted during code generation. ***/
  /*** RTOS startup code. Macro PEX_RTOS_START is defined by the RTOS component. DON'T MODIFY THIS CODE!!! ***/
  #ifdef PEX_RTOS_START
PEX_RTOS_START();                /* Startup of the selected RTOS. Macro is defined by the RTOS component. */
  #endif
  /*** End of RTOS startup code.  ***/
  /*** Processor Expert end of main routine. DON'T MODIFY THIS CODE!!! ***/
  for(;;) {
if(exit_code != 0) {
   break;
}
  }
  return exit_code;
  /*** Processor Expert end of main routine. DON'T WRITE CODE BELOW!!! ***/
} /*** End of main routine. DO NOT MODIFY THIS TEXT!!! ***/
/* END main */

/* Flex Timer Instance interrupt service routine*/
void ftmTimerISR(void)
{
static uint8_t s_overflowCount = 0U;
if(s_overflowCount < 10U)
{
s_overflowCount++;
}
else
{
GPIO_HAL_TogglePins(PTB , ((1 << 4U)|(1 << 5U)));
      s_overflowCount = 0U;
}
/* Clear FTM Timer Overflow flag */
FTM_HAL_ClearTimerOverflow(g_ftmBase[INST_FLEXTIMER1]);
}

请各位赐教，谢谢！
