把FL2440 的调试串口改为普通串口的方法

昨天，胡sir问我如何把FL2440 的调试串口改为普通串口，我答应他晚上回去看看，晕，昨晚忘记带笔记本电源回去了。所以现在立即补上——我没有在平台上试过，不过我看了一下BSP，我觉得应该是按照如下步骤改的
一、看F:/开发板光盘/FL24402010.01.28/FL2440/Wince/BSP源码包/SMDK2440A_091112/SMDK2440A/Src/Kernel/Oal 下的debug.c文件有：

//------------------------------------------------------------------------------

// Defines

#define DEBUG_SERIAL_UART0 1

//#define DEBUG_SERIAL_UART1 1

#ifdef DEBUG_SERIAL_UART0

#define FEILING_DEBUG 1

#elif DEBUG_SERIAL_UART1

#define FEILING_DEBUG 1

#else

#define FEILING_DEBUG 0

#endif

//------------------------------------------------------------------------------

如上说明FL2440 采用了 uart0作为 debug 串口。
再看F:/开发板光盘/FL24402010.01.28/FL2440/Wince/BSP源码包/SMDK2440A_091112/SMDK2440A 下的SMDK2440A.bat文件有
@REM DEBUG SERIAL PORT
@REM You also need to change the macro definition in debug.c
REM set DEBUG_SERIAL=
set DEBUG_SERIAL=SERIAL_UART0
REM set DEBUG_SERIAL=SERIAL_UART1

呵呵，正好和debug.c对应。
再来看F:/开发板光盘/FL24402010.01.28/FL2440/Wince/BSP源码包/SMDK2440A_091112/SMDK2440A/Files 下的platform.reg

; @CESYSGEN IF CE_MODULES_SERIAL

IF BSP_NOSERIAL !

IF BSP_NOUART0 !

IF BSP_KITL != SERIAL_UART0

IF DEBUG_SERIAL != SERIAL_UART0 ；这个宏定义造成uart0的驱动没有被加载成普通串口，呵呵，若要做普通串口，在SMDK2440A.bat把这个环境变量去掉

从上面可以看出，Fl2440 已经有了三个串口作为普通串口驱动注册表信心，甚至红外也保留了。

现在来看最后一步，看看串口驱动的源码F:/开发板光盘/FL24402010.01.28/FL2440/Wince/BSP源码包/SMDK2440A_091112/SMDK2440A/Src/Drivers/Serial/ser_smdk2440.cpp

CSerialPDD * CreateSerialObject(LPTSTR lpActivePath, PVOID pMdd,PHWOBJ pHwObj, DWORD DeviceArrayIndex)

{

CSerialPDD * pSerialPDD = NULL;

switch (DeviceArrayIndex) {

case 0:

pSerialPDD = new CPdd2440Serial1(lpActivePath,pMdd, pHwObj);

break;

case 1:

pSerialPDD = new CPdd2440Serial2(lpActivePath,pMdd, pHwObj);

break;

case 2:

pSerialPDD = new CPdd2440Serial3(lpActivePath,pMdd, pHwObj);

break;

}

if (pSerialPDD && !pSerialPDD->Init()) {

delete pSerialPDD;

pSerialPDD = NULL;

}

return pSerialPDD;

}

这个说明FL2440 已经完全具备三串口驱动，所以大家放心，调试串口很容易修改的。下面是修改结论：
一、F:/开发板光盘/FL24402010.01.28/FL2440/Wince/BSP源码包/SMDK2440A_091112/SMDK2440A/Src/Kernel/Oal 下的debug.c
中的#define DEBUG_SERIAL_UART0 1 屏蔽（//#define DEBUG_SERIAL_UART0 1）
二、F:/开发板光盘/FL24402010.01.28/FL2440/Wince/BSP源码包/SMDK2440A_091112/SMDK2440A 下的SMDK2440A.bat文件的
set DEBUG_SERIAL=SERIAL_UART0 屏蔽（@set DEBUG_SERIAL=SERIAL_UART0）即可，重新编译整个BSP，打包，我想这样com1 就可以当普通串口用了。呵呵。
