Date： 2011、12、13

1、Hosting environment：VMare ubuntu10.04

2、Cross-compiling environment：arm-2009q3.tar.bz2
3、Development board：QT6410
4、nanflash：K9F2G08(256M)

5、linux -version：Linux-2.6.39
6、uboot-version：u-boot-2010.06

一、下载并解压内核源码
a)在命令行终端中可以通过下列方式下载，当然用其它下载工具下载
root@bootloader:/home/eilian/development/Android#cd ../Linux

root@bootloader:/home/eilian/development/Linux# wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.39.tar.gz b)解压源码
root@bootloader:/home/eilian/development/Linux#

root@bootloader:/home/eilian/development/Linux# tar zxvf linux-2.6.39.tar.gz

root@bootloader:/home/eilian/development/Linux# ls

linux-2.6.32.2 linux-2.6.39

linux-2.6.36.2 linux-2.6.39.tar.bz2

linux-2.6.36.2.tar.gz linux-2.6.39.tar.gz

root@bootloader:/home/eilian/development/Linux# cd linux-2.6.39

root@bootloader:/home/eilian/development/Linux/linux-2.6.39#
c)指定交叉编译器
移植目的让 Linux-2.6.39 可以在QT6410 上运行。首先,使得Linux-2.6.39的缺省目标平台成为ARM 的平台,修改主目录下的Makefile。
用vi打开Makefile,定位到196行，修改如下：
root@bootloader:/home/eilian/development/Linux/linux-2.6.39# vi Makefile

# Default value for CROSS_COMPILE is not to prefix executables

# Note: Some architectures assign CROSS_COMPILE in their arch/*/Makefile

export KBUILD_BUILDHOST := $(SUBARCH)

ARCH ?= arm

CROSS_COMPILE ?= arm-linux-

# Architecture as present in compile.h

UTS_MACHINE := $(ARCH)

SRCARCH := $(ARCH)
修改完成后退出保存
二、创建目标平台
从smdk6410到qt6410

root@bootloader:/home/eilian/development/Linux/linux-2.6.39#cd arch/arm/mach-s3c64xx
root@bootloader:/home/eilian/development/Linux/linux-2.6.39/arch/arm/mach-s3c64xx#cp
mach-smdk6410.c mach-qt6410.c
将mach-mach-qt6410.c文件中的所有smdk6410改成qt6410

root@bootloader:/home/eilian/development/Linux/linux-2.6.39/arch/arm/mach-s3c64xx#vi mach-qt6410.c



修改mach-s3c64xx目录下的Makefile和Kconfig 修改如下：
Kconfig:添加如下红色代码
config MACH_SMDK6410

bool "SMDK6410"

select CPU_S3C6410

select SAMSUNG_DEV_ADC

select S3C_DEV_HSMMC

select S3C_DEV_HSMMC1

select S3C_DEV_I2C1

select SAMSUNG_DEV_IDE

select S3C_DEV_FB

select S3C_DEV_RTC

select SAMSUNG_DEV_TS

select S3C_DEV_USB_HOST

select S3C_DEV_USB_HSOTG

select S3C_DEV_WDT

select SAMSUNG_DEV_KEYPAD

select SAMSUNG_DEV_PWM

select HAVE_S3C2410_WATCHDOG if WATCHDOG

select S3C64XX_SETUP_SDHCI

select S3C64XX_SETUP_I2C1

select S3C64XX_SETUP_IDE

select S3C64XX_SETUP_FB_24BPP

select S3C64XX_SETUP_KEYPAD

help

Machine support for the Samsung SMDK6410

config MACH_QT6410

bool "QT6410"

select CPU_S3C6410

select SAMSUNG_DEV_ADC

select S3C_DEV_HSMMC

select S3C_DEV_HSMMC1

select S3C_DEV_I2C1

select SAMSUNG_DEV_IDE

select S3C_DEV_FB

select S3C_DEV_RTC

select SAMSUNG_DEV_TS

select S3C_DEV_USB_HOST

select S3C_DEV_USB_HSOTG

select S3C_DEV_WDT

select SAMSUNG_DEV_KEYPAD

select SAMSUNG_DEV_PWM

select HAVE_S3C2410_WATCHDOG if WATCHDOG

select S3C64XX_SETUP_SDHCI

select S3C64XX_SETUP_I2C1

select S3C64XX_SETUP_IDE

select S3C64XX_SETUP_FB_24BPP

select S3C64XX_SETUP_KEYPAD

help

Machine support for the Samsung QT6410

Makefile:添加如下红色代码
obj-$(CONFIG_MACH_ANW6410) += mach-anw6410.o

obj-$(CONFIG_MACH_SMDK6400) += mach-smdk6400.o

obj-$(CONFIG_MACH_SMDK6410) += mach-smdk6410.o

obj-$(CONFIG_MACH_QT6410) += mach-qt6410.o

obj-$(CONFIG_MACH_REAL6410) += mach-real6410.o

obj-$(CONFIG_MACH_MINI6410) += mach-mini6410.o

obj-$(CONFIG_MACH_NCP) += mach-ncp.o

obj-$(CONFIG_MACH_HMT) += mach-hmt.o

obj-$(CONFIG_MACH_SMARTQ) += mach-smartq.o

obj-$(CONFIG_MACH_SMARTQ5) += mach-smartq5.o

obj-$(CONFIG_MACH_SMARTQ7) += mach-smartq7.o

三、About machine Number
打开arch/arm/tools/mach-types文件定位到217行左右,修改如下
at91sam9g20ek MACH_AT91SAM9G20EK AT91SAM9G20EK 1624

qt6410 MACH_QT6410 QT6410 1626

u300 MACH_U300 U300 1627

这需要两者相匹配，如果内核的机器码和bootloader 传入的不匹配，就会经常出现下面的错误：

Uncompressing Linux................................................................................................................................. done, booting

the kernel. 不动了
接着修改linux-2.6.39/arch/arm/mach-s3c64xx/qt6410.c定位到文件末尾处

MACHINE_START(S3C6410, "SMDK6410") ， 将其修改为

MACHINE_START(QT6410, "QT6410
development board")

notes：开发板运行后，在命令行终端输入：cat /proc/cpuinfo 可以看到我们添加的开发板信息，当然这个信息可以定制成我们需要的信息

四、配置、编译测试
root@bootloader:/home/eilian/development/Linux/linux-2.6.39#cp arch/arm/configs/s3c6400_defconfig .config

root@bootloader:/home/eilian/development/Linux/linux-2.6.39#make menuconfig

出现下图所示内核配置根菜单



按上下箭头键移动到 System Type，按回车进入该子菜单，如图



设置完后退出

root@bootloader:/home/eilian/development/Linux/linux-2.6.39#make
uImage
等待若干久后出现
