Can not find EDMA3 synchronous event in the TMS320C6457 with CCS4.2

In my project,I config  the EDMA synchronous event is the CSL_EDMA3_CHA_GPINT10,and my Code for GPIO PIN10 like this:

/* Initialize the GPIO CSL module */
    status = CSL_gpioInit(&pContext);
    if (status != CSL_SOK) {
        printf("GPIO: Initialization error.\n");
        return;
    }

    /* Open the CSL module */
    hGpio = CSL_gpioOpen(&gpioObj, CSL_GPIO, NULL, &status);
    if ((hGpio == NULL) || (status != CSL_SOK)) {
        printf("GPIO: Error opening the instance.\n");
        return;
    }
        
  
    /* Setup hardware parameters */
    hwSetup.extendSetup = NULL;
    
    /* Setup the General Purpose IO */
    status = CSL_gpioHwSetup(hGpio, &hwSetup);

/* Configure pin 10 to generate an interrupt on Rising Edge, and
     * configure it as an input
     */
    config.pinNum = CSL_GPIO_PIN10;
    config.trigger = CSL_GPIO_TRIG_RISING_EDGE;
    config.direction = CSL_GPIO_DIR_INPUT;

    /* configure the gpio pin 10 */
    status = CSL_gpioHwControl(hGpio, CSL_GPIO_CMD_CONFIG_BIT, &config);
    if (status != CSL_SOK) {
        printf("GPIO: GPIO pin configuration error.\n");
        return;
    }

    /* Event Enable */
    HWI_eventMap(C64_INT11, CSL_INTC_EVENTID_GPINT10);
  
    C64_enableIER(C64_EINT11);
	    
    /* Enable the bank interrupt */
    status = CSL_gpioHwControl(hGpio, CSL_GPIO_CMD_BANK_INT_ENABLE, NULL);

Also,I use the FPGA to generate one rising edge interrupt in the GPIOPIN10.

While debugging my project ,I find that I can run into the ISR function of the HWI_11,

but there is no event appear in the ER/ERH register(I have enabled the event );

besides, if I mannually trigger the EDMA,the EDMA can work well.

if anybody has the same problem, thank you for your reply!
