嵌入式Linux2.6.32系统移植 – LCD

主机：RHEL6.0(2.6.32-220.2.1.el6.i686)

开发板：FL2440

编译器:arm-unknown-linux-gnueabi-gcc-4.4.6

LCD型号：东华WXCAT35-TG3#001

@@arch/arm/mach-s3c2440/mach-smdk2440.c

##实现1：

修改smdk2440_lcd_cfg __initdata内容如下1(有闪烁，大小正常)：

##参考http://soboer.iteye.com/blog/1286494

static struct s3c2410fb_display smdk2440_lcd_cfg __initdata = {
        .lcdcon5        = S3C2410_LCDCON5_FRM565 |
                S3C2410_LCDCON5_INVVCLK |
                          S3C2410_LCDCON5_INVVLINE |
                          S3C2410_LCDCON5_INVVFRAME |
                          S3C2410_LCDCON5_PWREN |
                          S3C2410_LCDCON5_HWSWP,
        .type           = S3C2410_LCDCON1_TFT,
          .width          = 320,
        .height         = 240,
        .pixclock       = 270000, /* HCLK 100 MHz, divisor 10 */
        .xres           = 320,
        .yres           = 240,
        .bpp            = 16,
        .left_margin    = 8,
        .right_margin   = 5,
        .hsync_len      = 63,
        .upper_margin   = 15,
        .lower_margin   = 13,
        .vsync_len      = 5,
}

##实现2：

修改smdk2440_lcd_cfg __initdata内容如下2(闪烁不明显，大小正常)：

##参考：

static struct s3c2410fb_display smdk2440_lcd_cfg __initdata = {
        .lcdcon5        = S3C2410_LCDCON5_FRM565 |
                          S3C2410_LCDCON5_INVVCLK |
                          S3C2410_LCDCON5_INVVLINE |
                          S3C2410_LCDCON5_INVVFRAME |
                          S3C2410_LCDCON5_PWREN |
                          S3C2410_LCDCON5_HWSWP,
        .type           = S3C2410_LCDCON1_TFT,
        .width          = 320,
        .height         = 240,
        .pixclock       = 156000,
        .xres           = 320,
        .yres           = 240,
        .bpp            = 16,
        .left_margin    = 20,
        .right_margin   = 38,
        .hsync_len      = 30,
        .upper_margin   = 12,
        .lower_margin   = 15,
        .vsync_len      = 3,
};

修改smdk2440_fb_info __initdata,将.lpcsel = ((0xCE6) & ~7) | 1<<4,

改为 .lpcsel = 0x00,

至此，LCD移植成功.
