友堅6410其BSP的默認調試串口爲com0（STEPLDR、EBOOT、Wince的都是），現在在wince中使用COM0想把調試口修改到wince的COM3，可以如下操作。
修改E:/WINCE600/PLATFORM/SMDK6410/SMDK6410.bat中的
set BSP_NOUART0=1
set BSP_NOUART1=
set BSP_NOUART2=
set BSP_NOUART3=
……
set BSP_DEBUGPORT=SERIAL_UART0
@REM set BSP_DEBUGPORT=SERIAL_UART1
@REM set BSP_DEBUGPORT=SERIAL_UART2
@REM set BSP_DEBUGPORT=SERIAL_UART3
修改爲：
set BSP_NOUART0=
set BSP_NOUART1=
set BSP_NOUART2=
set BSP_NOUART3=1
……
@REM set BSP_DEBUGPORT=SERIAL_UART0
@REM set BSP_DEBUGPORT=SERIAL_UART1
@REM set BSP_DEBUGPORT=SERIAL_UART2
set BSP_DEBUGPORT=SERIAL_UART3
重新生成STEPLDR.bin、EBOOT.bin、nk.bin燒入核心板啓動，Wince啓動後在
DEBUG: CreateSerialObject 2
OALIntrRequestSysIntr(irq = 63, sysIntr = 30)
卡住
尋找資料後，需要修改E:/WINCE600/PLATFORM/SMDK6410/CESYSGEN/files/platform.reg，把
