freeetos 移植是不是有bug

   RT 的freertos 移植是不是有bug呀。在中断中获取信号量之类的操作都会挂机。   [mw_shl_code=c,true]void FingerTech_KeyInit(void)
{
        //éÏéyÑØ′￥·￠
        gpio_pin_config_t  fingertech_led = {kGPIO_DigitalInput,0,kGPIO_IntRisingEdge};
         
        IOMUXC_SetPinMux(IOMUXC_SNVS_WAKEUP_GPIO5_IO00,0U);
        IOMUXC_SetPinConfig(IOMUXC_SNVS_WAKEUP_GPIO5_IO00,0x01B0B0u);  
       
        EnableIRQ(GPIO5_Combined_0_15_IRQn);
        GPIO_PinInit(GPIO5,(0U),&fingertech_led);
        GPIO_PortEnableInterrupts(GPIO5,1 << (0U));
}

//&#214;D&#182;&#207;′|àíoˉêy
void GPIO5_Combined_0_15_IRQHandler(void)
{
    BaseType_t xHigherPriorityTaskWoken;
    BaseType_t xResult;
    xHigherPriorityTaskWoken = pdFALSE;
   
    GPIO_PortClearInterruptFlags(GPIO5, 1U << 0U);

    PRINTF("xxxx ggggggggggggggggg i am fingerprint eint\r\n");
        #if 0
    if(gFingerTech_fingerEventGroup == NULL)
    {
        PRINTF("gFingerTech_fingerEventGroup is null\r\n");
    }
    xResult = xEventGroupSetBitsFromISR(gFingerTech_fingerEventGroup,0x01,&xHigherPriorityTaskWoken);
    if(xResult != pdFAIL)
    {
     portYIELD_FROM_ISR( xHigherPriorityTaskWoken );
    }
        #endif
       
        xResult = xSemaphoreGiveFromISR(xSemaphore, &xHigherPriorityTaskWoken);
        if(xResult != pdFAIL)

跑的是官方demo?

找到问题了，是由于中断优先级没有设置好，导致使用的中断号不在freertos的管理范围内导致的崩溃。
