根据文档进行了alarm创建和启动，发现并没有跳到闹钟回调函数

void user_alarm_callback(rt_alarm_t alarm, time_t timestamp)

    struct rt_alarm * alarm = RT_NULL;
    static time_t now;

        return;

/* 获取当前时间戳，并把下一秒时间设置为闹钟时间 */
    now = time(NULL) + 1;
    gmtime_r(&now,&p_tm);

    setup.wktime.tm_year = p_tm.tm_year;

        rt_kprintf("user alarm ok.\n");
    }
}

int main(void)
{
  
  
   set_date(2018, 12, 3);

   alarm_sample();
  
  
}
这是代码

@张世争 换了最新版本可以了 但是闹钟和我设定得不一样

这是程序
static void rtc_alarm_hour_create(void)
{
    static time_t now;
    struct tm *p_tm;
    struct rt_alarm_setup alarm_setup_test;

if (p_alarm_hour != RT_NULL)
        return;

now = time(NULL);
    p_tm = localtime(&now);
    alarm_setup_test.flag = RT_ALARM_SECOND;
    alarm_setup_test.wktime.tm_year = p_tm->tm_year;
    alarm_setup_test.wktime.tm_mon = p_tm->tm_mon;
    alarm_setup_test.wktime.tm_mday = p_tm->tm_mday;
    alarm_setup_test.wktime.tm_wday = p_tm->tm_wday;
    alarm_setup_test.wktime.tm_hour = p_tm->tm_hour ;
    alarm_setup_test.wktime.tm_min = p_tm->tm_min;
    alarm_setup_test.wktime.tm_sec = p_tm->tm_sec+5;

p_alarm_hour = rt_alarm_create(alarm_hour_cb, &alarm_setup_test);
    
     if(RT_NULL != p_alarm_hour)
    {
        rt_alarm_start(p_alarm_hour);
        rt_kprintf("user p_alarm_hour ok.\n");
    }
}

int main(void)
{
  
  
   set_date(2018, 12, 3);
   set_time(11, 15, 50);
//   rt_alarm_system_init();
   rt_kprintf("user alarm callback function.\n");
   rtc_alarm_hour_create();
  
  
}
