PWM和NVS冲突,造成PWM无输出

    ptNvsHandle = NVS_open(Board_NVS0, &tNvsParams);

    if (ptNvsHandle == NULL) {
        return ;
    }
    NVS_getAttrs(ptNvsHandle, &ptRegionAttrs);

        fDuty = 1;
    uiDuty = (uint32_t)(PWM_DUTY_FRACTION_MAX * fDuty);

	    /* 如果修改PWMInit->eIdleLevel达到停止PWM时输出的电平*/
        if(ptgPwmHandleLed0 == NULL)

            ptgPwmHandleLed0 = ptPwmInit(CC1310DK_4XD_PWM0, PWM_IDLE_LOW, 1, 0);
            PWM_stop(ptgPwmHandleLed0);

	    {
            ptgPwmHandleLed0 = ptPwmInit(CC1310DK_4XD_PWM0, PWM_IDLE_LOW, uiFreq, uiDuty);
	    }
	    else
	    {
	        PWM_stop(ptgPwmHandleLed0);
            PWM_setPeriod(ptgPwmHandleLed0, uiFreq);

void vMainTaskFunction(UArg arg0, UArg arg1)
{
    float j=0.01;
#if 0	//A	
    vNVSInit();
    vSetLed0(E_LED_ON, 50, j);    
#else
	vSetLed0(E_LED_ON, 50, j);    
    vNVSInit();
#endif
    for(;;)
    {
        Task_sleep(100000);
        j += 0.05;
        if(j>1)
            j=0.01;
        vSetLed0(E_LED_ON, 50, j);    
    }
}

实际使用时,NVS在一个更高优先级的任务中初始化,PWM在低优先级任务中初始化,为方便测试整合到一个任务中发现问题如下:

不初始化NVS时PWM工作正常(NVS代码在其它项目中已经验证过没有问题).

将NVS放到PWM之后初始化,PWM工作正常.

NVS放到PWM之前初始化PWM无输出.

如何解决此问题,不可能调整初始化顺序后就不管了吧
