TC275屏蔽掉GPIO_DEMO函数后while循环不在执行怎么解决？

int core0_main (void){    __enable ();    /*     * !!WATCHDOG0 AND SAFETY WATCHDOG ARE DISABLED HERE!!     * Enable the watchdog in the demo if it is required and also service the watchdog periodically     * */    IfxScuWdt_disableCpuWatchdog (IfxScuWdt_getCpuWatchdogPassword ());    IfxScuWdt_disableSafetyWatchdog (IfxScuWdt_getSafetyWatchdogPassword ());    GPIO_Demo_init();    while (1)    {            GPIO_Demo();            babywen ++;            if(babywen > 10000000)                    babywen = 0;    }    return (1);}屏蔽掉GPIO_DEMO（IO翻转）函数后while循环不在执行（依据是变量观测未发生变化），不屏蔽的时候一切正常
