LCD

1.在arch/arm/mach-s3c2410/mach-smdk2410.c中添加头文件：

#include

#include

#include

2.继续在上面的文件中添加

 

static struct s3c2410fb_mach_info smdk2410_lcdcfg __initdata={

 .fixed_syncs= 0,

 .regs={

              .lcdcon1= （7<<8）|(0<<7)|(3<<5)|(12<<1), 

              .lcdcon2=  (4<<24)|(239<<14)(4<<6)|4,

              .lcdcon3=   (13<<19)|(319<<8)|4,

              .lcdcon4=   (13<<8)|18,

              .lcdcon5=   (1<<11)|(1<<10)|(1<<9)|(1<<8)|(0<<7)|(0<<6)|(1<<3)|(0<<1)|(1),

       },

.type=S3C2410_LCDCON1_TFT,

.lpcsel=   ((0XCE6)&~7)|1<<4,//0x0,

.width=       320,//640,

.height=      240,//480,

.xres = {

.min = 322,

.max = 320,

.defval = 320,

},

.yres = {

.min = 240,

.max = 240,

.defval = 480,

},

.bpp = {

.min = 16,

.max = 16,

.defval = 16,

 },

};

在smdk2410_init函数里添加：

static void __init smdk2410_init(void)

{

       s3c24xx_fb_set_platdata(&smdk2410_lcdcfg);

       platform_add_devices(smdk2410_devices, ARRAY_SIZE(smdk2410_devices));

       smdk_machine_init();

}

下面配置内核

Device Drivers  ---> 
    Graphics support  --->
        <*> S3C2410 LCD framebuffer support

        <*> Virtual Frame Buffer support(ONLY FOR TESTING!) 
        Console display driver support  --->
            <*> Framebuffer Console support
            [*]   Framebuffer Console Rotation
            [*] Select compiled-in fonts
            [*]   VGA 8x8 font
            [*]   VGA 8x16 font
            [*]   Mini 4x6 font
            [*] Sparc console 8x16 font          
        [*] Bootup logo  --->
            --- Bootup logo
            [*]   Standard 224-color Linux logo  

然后就是重新编译内核 ，tftp到开发板启动，应该就可以看到企鹅Tux了。但你如果想在LCD上显示自己的Logo，那下面我介绍一下自定义Logo的方法：
