FinSH RT-Thread Nano

rt-thread nano 4.1.1 finsh无法正常打开

本人萌新，在官网下载了RT-Thread nano的下载包，根据网络教程在STM32F103C8T6上进行移植，编译时发现缺少finsh_config.h，于是从RT-Thread nano 315版本中复制了一份

但仍然无法正常打开Finsh组件，现象如下

一些相关的代码：
Main.c（没有在while(1)死等）:
```c
#include "sys.h"	
#include "rtthread.h"
#include "led.h"

int main(void)
 {
	while(1){
		rt_kprintf("MAIN\n");
		LED0=0;
		rt_thread_mdelay(1000);
		LED0=1;
		rt_thread_mdelay(1000);
	}
 }

```
rtconfig.h(打开了HEAP，CONSOLE以及include了finsh_config.h)
```c
#define RT_USING_HEAP
#define RT_USING_SMALL_MEM
// </c>
// <c1>using tiny size of memory
// using tiny size of memory
//#define RT_USING_TINY_SIZE
// </c>
// </h>

// <h>Console Configuration
// <c1>Using console
// Using console
#define RT_USING_CONSOLE
// </c>
// <o>the buffer size of console <1-1024>
// the buffer size of console
// Default: 128 (128Byte)
#define RT_CONSOLEBUF_SIZE 256
// </h>

// <h>FinSH Configuration
// <c1>include finsh config
// Select this choice if you using FinSH 
#include "finsh_config.h"
```

board.c(时钟串口初始化以及output函数的实现)
```c
void rt_hw_board_init(void)
{
//#error "TODO 1: OS Tick Configuration."
    /* 
     * TODO 1: OS Tick Configuration
     * Enable the hardware timer and call the rt_os_tick_callback function
     * periodically with the frequency RT_TICK_PER_SECOND. 
     */
	SysTick_Config(SystemCoreClock / RT_TICK_PER_SECOND);
	#include "led.h"
    /* Call components board initial (use INIT_BOARD_EXPORT()) */
#ifdef RT_USING_COMPONENTS_INIT
    rt_components_board_init();
#endif

#if defined(RT_USING_USER_MAIN) && defined(RT_USING_HEAP)
    rt_system_heap_init(rt_heap_begin_get(), rt_heap_end_get());
#endif
}

#ifdef RT_USING_CONSOLE

static int uart_init(void)
{
//#error "TODO 2: Enable the hardware uart and config baudrate."
	usart_init(115200);
    return 0;
}
INIT_BOARD_EXPORT(uart_init);

void rt_hw_console_output(const char *str)
{
//#error "TODO 3: Output the string 'str' through the uart."
	
	/* 进入临界段 */
	rt_enter_critical();
	
	while(*str!='\0')
	{
		 /* 换行 */
    if (*str == '\n')//RT-Thread 系统中已有的打印均以 \n 结尾，而并非 \r\n，所以在字符输出时，需要在输出 \n 之前输出 \r，完成回车与换行，否则系统打印出来的信息将只有换行
    {
       USART_SendData(USART1, '\r');
	
	     while(USART_GetFlagStatus(USART1, USART_FLAG_TC)== RESET);
    }

USART_SendData(USART1, *(str++));
	
	  while(USART_GetFlagStatus(USART1, USART_FLAG_TC)== RESET);
		
	}
	 /* 退出临界段 */
	rt_exit_critical();  //注意：使用进入临界段语句rt_enter_critical(); 一定要使用退出临界段语句 rt_exit_critical();否则调度器锁住，无法进行调度

}
```

usart.c(getchar函数的实现)
```c
char	rt_hw_console_getchar(void){
	int ch = -1;
	if(USART_GetFlagStatus(USART1, USART_FLAG_RXNE) != RESET)
	{
         	ch = (int)USART_ReceiveData(USART1);
			   USART_ClearFlag(USART1, USART_FLAG_RXNE);
	}
	else
	{
			 
		if(USART_GetFlagStatus(USART1, USART_FLAG_ORE) != RESET)
		{
			 USART_ClearFlag(USART1, USART_FLAG_ORE);
		}
		rt_thread_mdelay(10);
			 
	}
	return ch;
}
```

finsh_config.h(1KB的栈大小)
```c
/* FinSH config file */

#ifndef __MSH_CFG_H__
#define __MSH_CFG_H__

// <<< Use Configuration Wizard in Context Menu >>>
#define RT_USING_FINSH
#define FINSH_USING_MSH
