这家伙很懒，什么也没写！

虚拟设备驱动如下 
```
#include <rtthread.h>
#include <rtdevice.h>
#include "board.h"
#include "drv_uart.h"

static rt_err_t  drv_uart_configure(struct rt_serial_device *serial, struct serial_configure *cfg);
static rt_err_t  drv_uart_control(struct rt_serial_device *serial, int cmd, void *arg);
static int       drv_uart_putc(struct rt_serial_device *serial, char c);
static int       drv_uart_getc(struct rt_serial_device *serial);
static rt_size_t drv_uart_dma_transmit(struct rt_serial_device *serial, rt_uint8_t *buf, rt_size_t size, int direction);

// 注册一个虚拟串口, 用来连接设备 
const struct rt_uart_ops _uart_opss =
{
    drv_uart_configure,
    drv_uart_control,
    drv_uart_putc,
    drv_uart_getc,
    drv_uart_dma_transmit
};

rt_err_t  drv_uart_configure(struct rt_serial_device *serial, struct serial_configure *cfg)
	 {
		  return (RT_EOK);
 }
 rt_err_t  drv_uart_control(struct rt_serial_device *serial, int cmd, void *arg)
 {
	  return (RT_EOK);
 }
 int       drv_uart_putc(struct rt_serial_device *serial, char c)
 {
	  return (1);
 }
 int       drv_uart_getc(struct rt_serial_device *serial)
 {
	 return (-1); 
 }
 rt_size_t drv_uart_dma_transmit(struct rt_serial_device *serial, rt_uint8_t *buf, rt_size_t size, int direction)
 {
 
  return (0);
 }

struct device_uart
{
    TLS_UART_REGS_T volatile *uart_device;

rt_uint32_t uart_irq_no;
};
#define   WM600_UART0    (TLS_UART_REGS_T *) HR_UART0_BASE_ADDR
static struct rt_serial_device  serialv;
 static struct device_uart       uartv =
{
    WM600_UART0,
    UART0_INT,
};

void virtul_uart_init(void)
{
    struct rt_serial_device *serial;
  struct device_uart      *uart;
	
	
	      serial  = &serialv;
        uart    = &uartv;
	     serial->ops              = &_uart_opss;
	
        rt_hw_serial_register(serial,
                              "vuart1",
                              RT_DEVICE_FLAG_RDWR | RT_DEVICE_FLAG_INT_RX,
                              uart);
}

INIT_BOARD_EXPORT(virtul_uart_init);

```
然后把finsh 设备改为 vuart1 即可, 亲测好用, 既方便调试(切到正常串口调试),又不占用串口(切到虚拟串口上使用)
