10 rtthread的硬件定时器在烧写程序后不工作

写了一个控制门的代码，开门时间20s，算出来每开1%用t时间，然后定时器以这个t时间执行回调函数。
下面是关门的代码
```
else if( g_workpara_1.mg_sidewindoor_config.mount_wall_windoor_target_portion == 0 )
        {
            if( g_workpara_1.mg_sidewindoor_config.mount_wall_windoor_target_portion  < 
                    g_workpara_1.mg_sidewindoor_config.mount_wall_windoor_cur_portion +10 )
            {
                rt_kprintf(" guiling bili kongzhillllllllllll\n");
             rt_kprintf("cur_portion=%4d   target=%4d\n",g_workpara_1.mg_sidewindoor_config.mount_wall_windoor_cur_portion,g_workpara_1.mg_sidewindoor_config.mount_wall_windoor_target_portion);
                /*如果当前状态不是关门，需要修改定时器溢出时间*/
                if( g_workpara_1.mg_sidewindoor_config.mount_wall_windoor_status != 2)
                {
                    //rt_kprintf("guan\n");
                    rt_kprintf("guan pertime = %d\n",g_workpara_1.mg_sidewindoor_config.sidewindw_close_ms);
                    rt_enter_critical();
                    rt_timer_stop( mount_wall_windoor_timer );
                    rt_timer_control(mount_wall_windoor_timer, RT_TIMER_CTRL_SET_TIME ,&g_workpara_1.mg_sidewindoor_config.mount_wall_windoor_close_ms );
                    rt_timer_start( mount_wall_windoor_timer );
                    rt_exit_critical();
                    // rt_kprintf("sidewindow_timer again\n");
                    /*修改当前状态为关门*/
                    g_workpara_1.mg_sidewindoor_config.mount_wall_windoor_status = 2;
                }
            }
            else if( g_workpara_1.mg_sidewindoor_config.mount_wall_windoor_target_portion  >= 
                    g_workpara_1.mg_sidewindoor_config.mount_wall_windoor_cur_portion +10 )
            {
                g_workpara_1.mg_sidewindoor_config.mount_wall_windoor_status = 0;
            }
        }
```
程序是走关门这个分支的，门状态为2，需要关门，在定时器回调函数里，当前比例-1，但是定时器的回调函数，却不动了，什么都不执行，也不-1
```
/* wind door control timer callback function*/
void mount_wall_windoor_timeout(void * para)
{
	
		 // rt_kprintf(" mount wall windoor timeout!\n");
		if( g_workpara_1.mg_sidewindoor_config.mount_wall_windoor_status == 1 )
		{
			//rt_kprintf("real kai\n");
			g_workpara_1.mg_sidewindoor_config.mount_wall_windoor_cur_portion += 1;
			
			MG_ctrl_mountwall_winddoor(1);
		}
		else if( g_workpara_1.mg_sidewindoor_config.mount_wall_windoor_status == 2 )
		{
			rt_kprintf("real guan\n");
			g_workpara_1.mg_sidewindoor_config.mount_wall_windoor_cur_portion -= 1;
		  MG_ctrl_mountwall_winddoor(2);
		}
		else if( g_workpara_1.mg_sidewindoor_config.mount_wall_windoor_status == 0 )
		{

MG_ctrl_mountwall_winddoor(0);
		}
   
}
```
希望大家给一些思路，谢谢
