wince 5.0 移植到 utu2440 开发板记录

1、修改时钟频率 需要修改为   FCLK = 400M   HCLK = 100M   PCLK = 50M 跟据以上关系，则需要设置   HDIVN = 2   PDIVN = 1   HCLK3_HALF = 0   HCLK4_HALF = 0 计算出   CLKDIVN = 0x05   需要修改的文件有 src/Bootloader/Eboot/startup.s

    ;Apollo +
    ;PLLVAL EQU (((0x6e << 12) + (0x3 << 4) + 0x1))    ; 2440A 399MHz
    PLLVAL EQU (((0x5C << 12) + (0x1 << 4) + 0x1))    ; Fin=12MHz,Fout=400MHz
    UPLLVAL EQU (((0x38 << 12) + (0x2 << 4) + 0x2))    ; Fin=12MHz,Fout=48MHz
    ;Apollo -


     ldr r0, = UPLLCON ; Fin=16MHz, Fout=48MHz
    ;Apollo +
    ; ldr r1, = ((0x3c << 12) + (0x4 << 4) + 0x2)        ; 16Mhz
    ; ldr r1, = ((0x38 << 12) + (0x2 << 4) + 0x2)     ; 12Mhz
     ldr r1, = UPLLVAL
    ;Apollo -

Src/Kernel/Oal/startup.s

    ;Apollo +
        ldr r0, = UPLLCON
    ;    ldr r1, = ((0x3c << 12) + (0x4 << 4) + 0x2)
        ldr r1, = ((0x38 << 12) + (0x2 << 4) + 0x2)
    ;Apollo -

        ldr        r0, = MPLLCON
    ;Apollo +
    ;    ldr r1, = ((0x3e << 12) + (0x2 << 4) + 0x1) ; 296MHz
    ;    ldr r1, = ((0x6e << 12) + (0x3 << 4) + 0x1) ; 399MHz
        ldr r1, = ((0x5C << 12) + (0x1 << 4) + 0x1) ; 400MHz
    ;Apollo -


src/Inc/bsp_cfg.h

    //Apollo + 修改为12M晶振

    //#define S3C2440A_FCLK        (2 * (((PLLVALUE >> 12) & 0xff) + 8L) * (16934400L / (((PLLVALUE >> 4) & 0x3f)+2L) / (1<<((PLLVALUE >> 0) & 0x3))))    // PLLVALUE = v_pCLKPWRreg->MPLLCON

    #define S3C2440A_FCLK        (2 * (((PLLVALUE >> 12) & 0xff) + 8L) * (12000000L / (((PLLVALUE >> 4) & 0x3f)+2L) / (1<<((PLLVALUE >> 0) & 0x3))))    // PLLVALUE = v_pCLKPWRreg->MPLLCON

    //Apollo -



特别注意，bootloader中时钟频率的设置与内核中必须一致，否则会导致一些问题，比如usb host驱动的问题
另外，在bootloader中必须设置upllcon

uboot/cpu/arm920t/start.S

    ldr r0, = 0x4c000008 ; Fin=12MHz, Fout=48MHz
    ldr r1, = ((0x38 << 12) + (0x2 << 4) + 0x2)     ; 12Mhz
    str r1, [r0]


 

2、修改调试串口

默认的调试串口是UART1，需要修改为UART0

src/Inc/bsp_cfg.h

    //Apollo +

    #define BSP_UART0_ULCON 0x03 // 8 bits, 1 stop, no parity

    #define BSP_UART0_UCON 0x0245 // pool mode, PCLK for UART

    #define BSP_UART0_UFCON 0x00 // disable FIFO

    #define BSP_UART0_UMCON 0x00 // disable auto flow control

    #define BSP_UART0_UBRDIV (S3C2440A_PCLK/(DEBUG_BAUDRATE*16) - 1)
    //Apollo -



src/Kernel/Oal/debug.c

修改 OEMInitDebugSerial()函数

//Apollo +

/*
    // GPH2 and GHP3 are UART1 Tx and Rx, respectively.
    //
    CLRREG32(&pIOPortReg->GPHCON, (3 << 8)|(3 << 10));
    SETREG32(&pIOPortReg->GPHCON, (2 << 8)|(2 << 10));

    // Disable pull-up on TXD1 and RXD1.
    //
    SETREG32(&pIOPortReg->GPHUP, (1 << 4)|(1 << 5));

    // UART1 (TXD1 & RXD1) used for debug serial.
    //
    g_pUARTReg = (S3C2440A_UART_REG *)OALPAtoVA(S3C2440A_BASE_REG_PA_UART1, FALSE);

    // Configure the UART.
    //
    OUTREG32(&g_pUARTReg->UFCON, BSP_UART1_UFCON);
    OUTREG32(&g_pUARTReg->UMCON, BSP_UART1_UMCON);
    OUTREG32(&g_pUARTReg->ULCON, BSP_UART1_ULCON);
    OUTREG32(&g_pUARTReg->UCON, BSP_UART1_UCON);
    OUTREG32(&g_pUARTReg->UBRDIV, BSP_UART1_UBRDIV);
*/
    // GPH2 and GHP3 are UART0 Tx and Rx, respectively.

    //

    CLRREG32(&pIOPortReg->GPHCON, (3 << 4)|(3 << 6));
    SETREG32(&pIOPortReg->GPHCON, (2 << 4)|(2 << 6));

    // Disable pull-up on TXD0 and RXD0.

    //

    SETREG32(&pIOPortReg->GPHUP, (1 << 2)|(1 << 3));

    // UART0 (TXD0 & RXD0) used for debug serial.

    //

    g_pUARTReg = (S3C2440A_UART_REG *)OALPAtoVA(S3C2440A_BASE_REG_PA_UART0, FALSE);

    // Configure the UART.

    //

    OUTREG32(&g_pUARTReg->UFCON, BSP_UART0_UFCON);
    OUTREG32(&g_pUARTReg->UMCON, BSP_UART0_UMCON);
    OUTREG32(&g_pUARTReg->ULCON, BSP_UART0_ULCON);
    OUTREG32(&g_pUARTReg->UCON, BSP_UART0_UCON);
    OUTREG32(&g_pUARTReg->UBRDIV, BSP_UART0_UBRDIV);
//Apollo -



为了打印调试信息，先临时关闭系统的UART0串口驱动

smdk2440.bat

    @REM Apollo +
    @REM set BSP_NOUART0=

    @REM Apollo -


3、修改NAND FLASH驱动

    #define USE_UBOOT
    #ifdef USE_UBOOT
        #define RESERVED_BLOCK                            (0x800/SB_BLOCK_LOOP)
        #define RESERVED_SECTOR                            (RESERVED_BLOCK*PAGES_PER_BLOCK)
        #define TRANSLATE_SECTOR(s) ((s) = (s) + RESERVED_SECTOR)
        #define BLOCK_TO_ADDRESS(b) ((b) = (b) + RESERVED_BLOCK)
    #endif

     m_colorDepth = 16;
     m_cxPhysicalScreen = LCD_XSIZE_TFT;
     m_cyPhysicalScreen = LCD_YSIZE_TFT;
    //Apollo -



Src/Kernel/Oal/bitmap.c

 使用bmp2c工具，生成新的ScreenBitmap数组，替换原有内容，可设置新的开机画面

6、触摸屏驱动

触摸屏驱动源码不用修改，只需要修改platform.reg中触摸屏的5个校验点坐标

Src/Drivers/Touch/s3c2440a_touch.cpp

 

    在DdisTouchPanelGetPoint，函数一开始，添加坐标点调试信息输出
    //Apollo +

     RETAILMSG(1,(TEXT("DdsiTouchPanelGetPoint:: *pUncalX=%d, *pUncalY=%d/r/n"),*pUncalX,*pUncalY));
    //Apollo -

    然后想象运行了触摸屏校验程序(如果能够实际启动触摸屏校验程序则更好)，按照 中、左上、左下、右下、右上的顺序依次记录5个校验坐标点，写入platform.reg中，即可
    ;Apollo +
     "CalibrationData"="956,536 1688,984 236,976 288,88 1700,92 "

     dwType = REG_DWORD;
    
     if(dwStatus == ERROR_SUCCESS && dwType == REG_DWORD)
     {
     dwSize = sizeof(DWORD);
     //下面读取失败的话那么就用初始值作为MAC地址

     dwStatus = RegQueryValueEx(hkMAC, _T("MAC12"), NULL, &dwType, (LPBYTE) &MAC, &dwSize);
     if (dwStatus == ERROR_SUCCESS)
     {
     iMAC[0]=MAC;
