把FL2440 的调试串口改为普通串口的方法

把FL2440 的调试串口改为普通串口的方法

串口, 调试

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 //------------------------------------------------------------------------------ 复制代码 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 ;=============== UART0 (physical COM1 connector P1) (Serial) =============== [HKEY_LOCAL_MACHINE/Drivers/BuiltIn/Serial]    "DeviceArrayIndex"=dword:0    "Irq"=dword:1c    "MemBase"=dword:50000000    "MemLen"=dword:2C    "InterruptBitsShift"=dword:0 ; UART 0 Interrupt Sub Register shift bit.    "ISTTimeouts"=dword:200        ; every 512 ticks checking Modem status.    "Prefix"="COM"    "Index"=dword:1    "Dll"="serial_smdk2440.dll"    "Order"=dword:4    "Priority"=dword:0    "Port"="COM1:"    "DeviceType"=dword:0    "FriendlyName"=LOC_DISPLAYNAME_COM1    "Tsp"="unimodem.dll"    "IClass"="{CC5195AC-BA49-48a0-BE17-DF6D1B0173DD}"    "DevConfig"=hex: 10,00, 00,00, 05,00,00,00, 10,01,00,00, 00,4B,00,00, 00,00, 08, 00, 00, 00,00,00,00     ENDIF ENDIF ENDIF IF BSP_NOUART1 !
