本文介绍如何在Eboot源码中修改启动时显示的画面。主要涉及修改Splash.c文件中的BspEbootDrawSplashWindow函数，并调整BspFunc.c文件中的BspEbootSupportSplash函数返回值来启用启动画面。

1）在 Splash.c (c:\wince600\platform\tt4x0bd\src\bootloader\eboot)中的函数修改成以下：
OALSYSINFO g_oalSysInfo;
#define EBOOT_LCD_FRAM_UNBUF_VIRT_ADDR 0xAC100000

void BspEbootDrawSplashWindow()
{
#if 0
DrvLibLcdSplashScreen(LCD_FRAME_BUF_VIRT_ADDR, LogoBitmap);
#else
g_oalSysInfo.displayInfo.bHasVip = TRUE;
g_oalSysInfo.displayInfo.dwLcdDevId = _ATLAS_LCD_PANEL;
g_oalSysInfo.displayInfo.dwWidth = DISPLAY_WIDTH;
g_oalSysInfo.displayInfo.dwHeight = DISPLAY_HEIGHT;
g_oalSysInfo.displayInfo.dwDepth = DISPLAY_DEPTH/8; // It does not work.
g_oalSysInfo.displayInfo.dwPadPins = 16;
//g_oalSysInfo.displayInfo.dwBacklightPwm = 5;

DrvLibLcdSplashScreen(EBOOT_LCD_FRAM_UNBUF_VIRT_ADDR, (unsigned char *)EBOOT_LCD_FRAM_UNBUF_VIRT_ADDR);

#endif
}

2）保证该函数能够执行到：

在 BspFunc.c (c:\wince600\platform\tt4x0bd\src\bootloader\eboot)中把 BspEbootSupportSplash() 的返回值从 FALSE 改成 TRUE

BOOL BspEbootSupportSplash()
{
EdbgOutputDebugString("========== FD EBOOT Logo Test ===============\r\n");
return TRUE;
}
