Mini2440打印串口调试信息，2440的串口0被应用层用于COM1，导致不能打印调试信息。做以下修改即可：1.首先在platform.reg屏蔽掉串口0的注册表信息【注册表前面加“;”就行了】。

;ENDIF
2、其次在目录WINCE500PLATFORMmini2440SrcInc中找到options.h找到

//#define KITL_NONE
#define KITL_SERIAL_UART0
//#define KITL_SERIAL_UART1
//#define KITL_USBSERIAL
//#define KITL_ETHERNET
然后 解除对#define KITL_SERIAL_UART0的屏蔽即可
