CC3220SF: Custom board can't wake up from Hibernate Mode

Hi team :

        I use CC3220SF as my custom board's IC. And some custom board after enter Hiberation mode can't wake up anymore except use HW reset.But some custom board execute as i expect.

        I use test code to ckeck which part cause this problem. My test code is  as follow.

#include <stddef.h>
#include <stdbool.h>
#include <stdint.h>
#include <string.h>

/* POSIX Header files */
#include <pthread.h>
#include <semaphore.h>
#include <unistd.h>
#include <stdint.h>
#include <stddef.h>
#include <stdlib.h>
#include <stdint.h>
#include <stdio.h>

/* Driver Header files */
#include <ti/drivers/GPIO.h>
#include <ti/drivers/SPI.h>
#include <ti/display/Display.h>
#include <ti/drivers/UART.h>
#include <ti/drivers/Power.h>
#include <ti/drivers/GPIO.h>
/* Driver configuration */
#include "ti_drivers_config.h"
// PRCM API stuff
#include <ti/devices/cc32xx/inc/hw_types.h>
#include <ti/devices/cc32xx/driverlib/prcm.h>
#include <ti/drivers/power/PowerCC32XX.h>

/*
 *  ======== mainThread ========
 */
void *mainThread(void *arg0)
{
    GPIO_init();
    GPIO_setConfig(LED, GPIO_CFG_OUT_STD | GPIO_CFG_OUT_LOW);
    GPIO_write(LED,0);

    PRCMHibernateWakeupSourceDisable(0x007F0001);

    sleep(3);
    GPIO_write(LED,1);

    PRCMHibernateWakeUpGPIOSelect(PRCM_HIB_GPIO4 | PRCM_HIB_GPIO11 | PRCM_HIB_GPIO17, PRCM_HIB_RISE_EDGE);
    PRCMHibernateWakeupSourceEnable(PRCM_HIB_GPIO4 | PRCM_HIB_GPIO11 | PRCM_HIB_GPIO17);
    PRCMHibernateEnter();

    return (NULL);
}

        At this test code,still encounter some custom board can't wake up from hibernation mode.

        I want to check,Am I using Hibernation function wrong.Or there is other reason will cause this problem?
