2、Cross-compiling environment：arm-2009q3.tar.bz2
3、Development board：QT6410
4、nanflash：K9F2G08(256M)
5、linux -version：Linux-2.6.39
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/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"
