usart在线程应用的一些问题

usart初始化好了后，并在board.c里rt_hw_usart_init();
我想在application.c文件里添加自己的usart线程，可以
```static char thread_uart1_stack[1024];
struct rt_thread thread_uart1;
static void rt_thread_entry_uart1(void* parameter) 
{
USART_Configuration();
  while (1)
  {
    UART_Send( Tx_Buffer, countof(Tx_Buffer)-1);
		delay(1000);
  }
}
int rt_application_init()
{
    rt_thread_t init_thread;

#if (RT_THREAD_PRIORITY_MAX == 32)
    init_thread = rt_thread_create("init",
                                   rt_init_thread_entry, RT_NULL,
                                   2048, 8, 20);
#else
    init_thread = rt_thread_create("init",
                                   rt_init_thread_entry, RT_NULL,
                                   2048, 80, 20);
#endif

if (init_thread != RT_NULL)
        rt_thread_startup(init_thread);

//------- init usat1 thread
    rt_thread_init(&thread_uart1,
                   "uart1",
                   rt_thread_entry_uart1,
                   RT_NULL,
                   &thread_uart1_stack[0],
                   sizeof(thread_uart1_stack),11,5);
    rt_thread_startup(&thread_led1);```

这样的线程可以么？
