原创 S3C2450 Bootloader调试总结之二

整个函数代码如下：

void BootloaderMain (void)

{

    DWORD dwAction;  

    DWORD dwpToc = 0;

    DWORD dwImageStart = 0, dwImageLength = 0, dwLaunchAddr = 0;

    BOOL bDownloaded = FALSE;

    // relocate globals to RAM

    // 将全局变量在RAM中声明

    if (!KernelRelocate (pTOC))

    {

        // spin forever

        HALT (BLERR_KERNELRELOCATE);

    }

    // (1) Init debug support. We can use OEMWriteDebugString afterward.

    // 初始化串口

    if (!OEMDebugInit ())

    {

        // spin forever

        HALT (BLERR_DBGINIT);

    }

    // output banner

    // 打印第一条信息:

    // Microsoft Windows CE Ethernet Bootloader Common Library Version 1.1 Built Jul 13 2009 00:17:59

    EdbgOutputDebugString (NKSignon, CURRENT_VERSION_MAJOR, CURRENT_VERSION_MINOR);

    // (3) initialize platform (clock, drivers, transports, etc)

    if (!OEMPlatformInit ())

    {

        // spin forever

        HALT (BLERR_PLATINIT);

    }

    // system ready, preparing for download

    EdbgOutputDebugString ("System ready!\r\nPreparing for download...\r\n");
