1、-U-boot 内核移植步骤：Linux 3.3.5 系统移植1. 将 arch/arm/mach-s3c6410/下的,mach-smdk6410.c cp 为 mach-my6410.c;2. 打开 arch/arm/mach-s3c6410/下的 Kconfig，仿照 MACH_SMDK6410 做一个菜单项：config MACH_MY6410bool “MY6410“select CPU_S3C6410select SAMSUNG_DEV_ADCselect S3C_DEV_HSMMCselect S3C_DEV_HSMMC1select S3C_DEV_I2C1select SAM
2、SUNG_DEV_IDEselect S3C_DEV_FBselect S3C_DEV_RTCselect SAMSUNG_DEV_TSselect S3C_DEV_USB_HOSTselect S3C_DEV_USB_HSOTGselect S3C_DEV_WDTselect SAMSUNG_DEV_BACKLIGHTselect SAMSUNG_DEV_KEYPADselect SAMSUNG_DEV_PWMselect HAVE_S3C2410_WATCHDOG if WATCHDOGselect S3C64XX_SETUP_SDHCIselect S3C64XX_SETUP_I2C1s
3、elect S3C64XX_SETUP_IDEselect S3C64XX_SETUP_FB_24BPPselect S3C64XX_SETUP_KEYPADhelpMachine support for the Pillar MY64103. 打开 arch/arm/tools/mach-types 文件，这里面存的是机器 ID 必须要和 uboot 里面的 ID 保持一致，将其 283 行复制添加在后面并修改为：smdk6410 MACH_SMDK6410 SMDK6410 1626xx6410 MACH_XX6410 XX6410 1626 这个机器 ID 和 UBOOT 里的机器 ID
4、 相同时才能启动内核；1. 修改 BSP 文件 mach-my6410.c,内容如下：将 mach-mach-my6410.c 文件中的所有 smdk6410 改成 my6410(不要改大写SMDK6410 的 )MACHINE_START(MY6410, “MY6410“)/这个要和 Kconfig 里的 MACH-MY6410 匹配 2. 在当前目录的 Makefile 最后一行加上 obj-$(CONFIG_MACH_MY6410) += mach-my6410.o3. 修改顶层的 Makefile：ARCH ?= armCROSS_COMPILE ?= /usr/local/arm/4
5、.2.2-eabi/usr/bin/arm-linux-4. 复制 arch/arm/configs/下的 s3c6400-defconfig 文件，然后将其保存为.config,配置内核支持 EABI，再选中 XX6410 board 这一项，保存退出；5. 执行 make menuconfig 对内核进行配置：执行 make 编译执行 make zImage 生成 zImage将 uboot 根目录下的 mkimage 拷贝到/user/bin 目录下执行 make uImage 生成 uImage通过以上几步 linux 内核移植完了，剩下就移植驱动了。这里需要注意，每一次修改 Kcon
6、fig 文件都需要 make menuconfig 对内核进行配置。LED 驱动移植1. Linu 内核下 drivers/leds/ledsgpio.c 实现了一个体系结构无关的 GPIO LED 驱动，使用此 LED 驱动，开发者不需要修改一行代码，只需要在 BSP 的板文件（对于 OK6410 为 arch/arm/machs3c6410/machmy6410.c）中定义相关的 platform 设备和数据。在 MY6410 开发板上 ,GPM0GPM3 实现了四个 LED，因此其对应的 platform 信息如下：arch/arm/machs3c6410/machmy6410.c:st
7、atic struct gpio_led my6410_leds =0= .name = “LED1“,.gpio = S3C64XX_GPM(0),1= .name = “LED2“,.gpio = S3C64XX_GPM(1),2= .name = “LED3“,.gpio = S3C64XX_GPM(2),3= .name = “LED4“,.gpio = S3C64XX_GPM(3), ;static struct gpio_led_platform_data my6410_gpio_led_pdata =.num_leds = ARRAY_SIZE(my6410_leds),.led
8、s =my6410_leds,;static struct platform_device my6410_device_led =.name = “leds-gpio“,.id = -1,.dev =.platform_data = 2. 将static struct gpio_keys_platform_data my6410_button_data =.buttons =my6410_buttons,.nbuttons =ARRAY_SIZE(my6410_buttons),;static struct platform_device my6410_device_button = .nam
9、e =“gpio-keys“,.id = -1,.dev = .platform_data =2. 将pixclock = 1000000 / DCLK = 1000000 / 9 = 111111left_margin = Thb = 2right_margin = Thf = 2hsync_len = Thp = 41upper_margin = Tvb = 2lower_margin = Tvf = 2vsync_len = Tvp = 10xres = Thd = 480Yres = Tvd = 272static struct map_desc my6410_iodesc = /*
10、LCD support */.virtual = (unsigned long)S3C_VA_LCD,.pfn = _phys_to_pfn(S3C_PA_FB),.length = SZ_16K,.type = MT_DEVICE,;1. 然后将 28 内核中的 drviers/video/samsung 拷贝到 drviers/video/目录下2. 修改 drviers/video/的 Kconfig 文件，在文件中加入source “drivers/video/samsung/Kconfig“3. 修改修改 drviers/video/的 Makefie 文件,再最后一行添加：obj-
11、$(CONFIG_FB_S3C_EXT) += samsung/4. 在 arch/arm/plat-samsung/include/plat/map-base.h 里面添加#define S3C_VA_LCD S3C_ADDR(0x01100000) /* LCD */1. 在 include/generated/atuoconfig.h 里面添加#define CONFIG_FB_S3C_EXT_NUM 42. 把 drivers/video/samsung/s3cfb_fimd4x.c 里面的第 1417 行：s3c6410_pm_do_save(s3c_lcd_save, ARRAY_
12、SIZE(s3c_lcd_save);改成s3c_pm_do_save(s3c_lcd_save, ARRAY_SIZE(s3c_lcd_save);第 1438 行s3c6410_pm_do_restore(s3c_lcd_save, ARRAY_SIZE(s3c_lcd_save);改成s3c_pm_do_restore(s3c_lcd_save, ARRAY_SIZE(s3c_lcd_save);1. 配置内核：Device Drivers -Graphics support -Support for frame buffer devices - （里面的都空选）Support for
13、frame buffer devices - Backlight 找到了原因。以后有时间好好对 LCD 驱动做一下分析。DM9000 网卡驱动移植1. Linux 内核里面已经 支持了 dm9000 的网卡驱动，所以驱动程序我们不需要写了，只需要添加 相应的平台信息。在 linux-3.3.5/arch/arm/mach-s3c64xx/mach-my6410.c 里面添加都文件#include 2. 在 linux-3.3.5/arch/arm/mach-s3c64xx/mach-my6410.c 里面添加以下平台信息：#define S3C64XX_PA_DM9000 (0x1800000
14、0)#define S3C64XX_SZ_DM9000 SZ_1Mstatic struct resource my6410_dm9000_resources = 0 = .start= S3C64XX_PA_DM9000,.end= S3C64XX_PA_DM9000 + 3,.flags= IORESOURCE_MEM,1 = .start= S3C64XX_PA_DM9000 + 4,.end= S3C64XX_PA_DM9000 + S3C64XX_SZ_DM9000 - 1,.flags= IORESOURCE_MEM,2 = .start= IRQ_EINT(7),.end= IR

16、m9000_resources),.resource= my6410_dm9000_resources,.dev= .platform_data = 然后在 static struct platform_device *my6410_devices _initdata =里面添加1. 启动过程中出现这样的问题：smsc911x: failed to claim resource 0（这个提示原来在这儿我怎么没有发现）- cut here -WARNING: at drivers/base/core.c:194 device_release+0x74/0x80()Device platform-

30、o 错误 1make: * miscutils 错误 2出现这么多的错误，核心问题就是出现在 miscutils/ubi_tools.c:63:26: error: mtd/ubi-user.h: No such file or directory 这个上面，无法找到 mtd/ubi-user.h 头文件，查阅了相关资料后，原来这是一个 Linux 下新支持的 UBI 文件系统，需要手 工加入。从 Linux3.3.5 的 includemtdubi-user.h 拷贝到 busybox 下的 includemtd 下，如果 busybox 下的 include 没有 mtd 文件夹，那就先建立一个 mtd 文件夹，然后复制了。这样做了之后，编译就 OK 了。出现下面的信息就说明编译成 功了。
