按照例程，在main函数中创建了两个线程
```c
/*******************************************************************************
    local functions
*******************************************************************************/

#define THREAD_PRIORITY         25
#define THREAD_STACK_SIZE       1024
#define THREAD_TIMESLICE        5

static rt_thread_t tid1 = RT_NULL;

static void thread1_entry(void *parameter)
{
    rt_uint32_t count = 0;

while (1)
    {
        rt_kprintf("thread1 count: %d\n", count ++);
        rt_thread_mdelay(500);
    }
}

ALIGN(RT_ALIGN_SIZE)
static char thread2_stack[1024];
static struct rt_thread thread2;
static void thread2_entry(void *param)
{
    rt_uint32_t count = 0;

for (count = 0; count < 10 ; count++)
    {
        rt_kprintf("thread2 count: %d\n", count);
    }
    rt_kprintf("thread2 exit\n");
}

int thread_sample(void)
{
    tid1 = rt_thread_create("thread1",
                            thread1_entry, RT_NULL,
                            THREAD_STACK_SIZE,
                            THREAD_PRIORITY, THREAD_TIMESLICE);
    
    if (tid1 != RT_NULL) {
			  rt_kprintf("FUNC[%s], LINE[%d]\n", __FUNCTION__, __LINE__);
        rt_thread_startup(tid1);
		}

rt_thread_init(&thread2,
                   "thread2",
                   thread2_entry,
                   RT_NULL,
                   &thread2_stack[0],
                   sizeof(thread2_stack),
                   THREAD_PRIORITY - 1, THREAD_TIMESLICE);
    rt_thread_startup(&thread2);

return 0;
}

/*******************************************************************************
    public functions
*******************************************************************************/

int main(void)
{
    uint32_t ret = E_ERROR;
    uint32_t loop_flag = 1;

rt_kprintf("Created time: %s[%s]\n", __DATE__, __TIME__); 	
	
   	thread_sample();

//while(1);
	
		while(1) {
		    rt_thread_mdelay(1000);
		    rt_kprintf("hello\n");
		}

if(loop_flag) {
        while(1) {
	    reg32_write(TUBE_BASE_ADDR, 0x23);
        }
    }
	
    /* never reach here */
    return 0;
}
```

但是创建的两个线程好像没有运行
