请教关于邮箱收发的问题

环境：keil 4.54， RTT1.1.0
现象描述：邮件内容更改后发送，接受并打印出来的邮件内容不变，且与邮件内容没有任何关系。。
代码如下，非常简单基本：
```c
static rt_thread_t test_send =RT_NULL;
static rt_thread_t test_recv =RT_NULL;

static struct rt_mailbox mb;
static unsigned char mb_pool[16];
static unsigned char mb_temp[4]={0xAA,0x11,0xAA,0x11};

static void send_entry(void* parameter)
{
	static unsigned char mb_local[]={0x11, 0xAA, 0x11, 0xAA};
	while(1)
	{
		rt_mb_send(&mb, (rt_uint32_t)&mb_temp[0]);
		rt_mb_send(&mb, (rt_uint32_t)&mb_local[0]);
		rt_kprintf("msg sent
");
		rt_thread_delay(RT_TICK_PER_SECOND);
	}
}

static void recv_entry(void* parameter)
{
	while(1)
	{
		if(rt_mb_recv(&mb, (rt_uint32_t*)&mb_temp, RT_WAITING_FOREVER)== RT_EOK)
		{
			rt_kprintf("Get new
");
			rt_kprintf("recv:%x %x %x %x
",mb_temp[0],mb_temp[1],mb_temp[2], mb_temp[3]);
			rt_thread_delay(10);
		}	
		else
		{
			rt_kprintf("Not recived
");
			rt_thread_delay(10);
		}
	}
}

int rt_application_init()
{
	rt_thread_t init_thread;
	rt_mb_init(&mb, "mbt", &mb_pool[0], sizeof(mb_pool)/4, RT_IPC_FLAG_FIFO);
        //后面的线程初始化部分暂时不写了，应该没有问题，因为可以正常运行并打印出结果
```

打印结果:

```

finsh>>msg sent
Get new
recv:8 0 0 20
Get new
recv:c 0 0 20
msg sent
...
```

如此循环，不管我把mb_temp 和 mb_local 里的内容做何修改，打印出来始终是8 0 0 20和c 0 0 20。。。

不解，请高人指点。
