现在我通过CubeMX生成了STM32H743ZITx的RT-Thread工程。
然后开启了如下的功能：

```c

```
系统进入的时候可以正常进入MSH命令行，但是当输入中文字符或使用上下左右键的时候，命令行卡死，无法输入或输出数据。但是程序我通过打断点发现没有挂掉。这个是什么原因啊？
同时，我发现，生成的工程中没有如下函数：

```c
static int stm32_getc(struct rt_serial_device *serial)
{
   int ch;
   struct stm32_uart *uart;
   RT_ASSERT(serial != RT_NULL);
   uart = rt_container_of(serial, struct stm32_uart, serial);

ch = -1;
   if (USART_GetITStatus(uart->handleInstance, USART_IT_RXNE) != RESET)
   {
#if defined(SOC_SERIES_STM32L4) || defined(SOC_SERIES_STM32F7) || defined(SOC_SERIES_STM32F0) \
   || defined(SOC_SERIES_STM32L0) || defined(SOC_SERIES_STM32G0) || defined(SOC_SERIES_STM32H7) \
   || defined(SOC_SERIES_STM32G4)
       ch = uart->config->Instance->RDR & 0xff;
#else
       ch = uart->config->Instance->DR & 0xff;
#endif
   }
   return ch;
}
```
但是系统可以正常进入命令行。代码因为涉及到一些加密的东西，所以不能全部上传。
RT-Thread的版本是RT-Thread 3.1.5，有哪位大佬可以帮忙解决一下该问题吗？万分感谢！！！！
