TMS320F28388D: 关于配置epwm中断设置但无法进入中断的问题

大家好，

我想要使用28388配置epwm5并执行中断配置，我按照例程interrupt_ex4_epwm_realtime_interrupt进行配置，在debug发现无法进入中断，但在debug时候我停止调试然后点击restart后又能重新进入中断，如果烧写离线程序又无法进入中断，不知道我的代码配置是否有问题，麻烦各位帮忙解答一下，谢谢。

下面附上我的代码，我使用的是ccs12.0版本，c2000Ware是4.03版本

主函数：

void main(void)
{
    Device_init();

    //
    // Boot CPU2 core
    //
#if    DEBUG
#ifdef _FLASH
    // Send boot command to allow the CPU2 application to begin execution
    Device_bootCPU2(BOOTMODE_BOOT_TO_FLASH_SECTOR0);
    Device_bootCM(BOOTMODE_BOOT_TO_FLASH_SECTOR0);
#else
    // Send boot command to allow the CPU2 application to begin execution
    Device_bootCPU2(BOOTMODE_BOOT_TO_M0RAM);
    Device_bootCM(BOOTMODE_BOOT_TO_S0RAM);
#endif
#endif

//    Device_initGPIO();

    // syscfg配置调用
    Board_init();

    //
    // Initialize PIE and clear PIE registers. Disables CPU interrupts.
    //
    Interrupt_initModule();

    //
    // Initialize the PIE vector table with pointers to the shell Interrupt
    // Service Routines (ISR).
    //
    Interrupt_initVectorTable();

    EPWM_init();

    INTERRUPT_init();

    //
    // Enable Global Interrupt (INTM) and realtime interrupt (DBGM)
    //
    EINT;
    ERTM;

    //
    // Loop Forever
    //
    for(;;)
    {
        
    }
}

Epwm初始化函数：

void EPWM_init(){

    SysCtl_setEPWMClockDivider(SYSCTL_EPWMCLK_DIV_1);
    
    SysCtl_disablePeripheral(SYSCTL_PERIPH_CLK_TBCLKSYNC);

    EPWM_setClockPrescaler(EPWM5_BASE, EPWM_CLOCK_DIVIDER_1, EPWM_HSCLOCK_DIVIDER_1);

    EPWM_disablePhaseShiftLoad(EPWM5_BASE);
    
    EPWM_setPhaseShift(EPWM5_BASE, 0);

    EPWM_setEmulationMode(EPWM5_BASE, EPWM_EMULATION_STOP_AFTER_FULL_CYCLE);

    EPWM_setTimeBasePeriod(EPWM5_BASE, myEPWM5_TBPRD);
    EPWM_setTimeBaseCounterMode(EPWM5_BASE, EPWM_COUNTER_MODE_UP_DOWN);
    EPWM_setTimeBaseCounter(EPWM5_BASE, 0U);

    EPWM_setPeriodLoadMode(EPWM5_BASE, EPWM_PERIOD_DIRECT_LOAD);

    EPWM_setInterruptSource(EPWM5_BASE, EPWM_INT_TBCTR_ZERO_OR_PERIOD);
    EPWM_enableInterrupt(EPWM5_BASE);
    EPWM_setInterruptEventCount(EPWM5_BASE, 1);

    SysCtl_enablePeripheral(SYSCTL_PERIPH_CLK_TBCLKSYNC);

}

使能中断：

void INTERRUPT_init(){

    // Interrupt Setings for INT_myEPWM5
    Interrupt_register(INT_myEPWM5, &INT_myEPWM5_ISR);
    Interrupt_enable(INT_myEPWM5);
}

中断服务函数：

__interrupt void INT_myEPWM5_ISR(void)
{
    count ++;
    if(count >= 8000)
    {
        GPIO_togglePin(DEVICE_GPIO_PIN_LED_3);
        count = 0;
    }
    
    EPWM_clearEventTriggerInterruptFlag(EPWM5_BASE);

    Interrupt_clearACKGroup(INTERRUPT_ACK_GROUP3);
}
