在使用 RT-Thread studio stlink调试 很简单的一个示例调试有时卡死，

```c
int main(void)
{
   tim_init();
    while (1)
   {
        //rt_thread_mdelay(2000);

}
    return RT_EOK;
}
============================================================
#ifndef APP_TIM_H_
#define APP_TIM_H_

#include <rtdevice.h>
#include <rtthread.h>

void tim_init();

#endif /* APP_TIM_H_ */
============================================================
#include "tim.h"

/*
 *  软件定时器
 *
 * */

rt_timer_t  tim1 =NULL ;

struct rt_timer tim2;

rt_err_t ret ;

void tim1_timeout(void *parameter) //定时器1回调(每到定时时间就进来一次)
{

rt_kprintf("ONE is OK\n ");

}

void tim2_timeout(void* parameter)//定时器2回调 (每到定时时间就进来一次)
{
    //rt_kprintf("TWO is OK\n ");
    static  int  count =0 ;
    if(count >=2)
    {
        rt_kprintf("TWO is OK\n ");
        count =0 ;
    }
    else {
        count ++;
    }
}

void tim_init()
{
    /*动态创建*/
    tim1 = rt_timer_create("tim1 demo",
                                tim1_timeout,
                                RT_NULL,
                                2000,  //定时时间2s一次
                                RT_TIMER_FLAG_ONE_SHOT );//单次定时

/*静态创建*/
     rt_timer_init(&tim2,
                       "tim2 demo ",
                       tim2_timeout,
                       RT_NULL,
                       1000, ////定时时间1s一次
                       RT_TIMER_FLAG_PERIODIC );//周期定时

if(tim1 !=NULL )
    {
        rt_timer_start(tim1);

}
         //启动定时器
             rt_timer_start(tim1);
             //rt_timer_start(&tim2);

}
```
