开发板：飞凌OK6410 nandflash,Kernel:2.6.36.2
编译器：arm-linux-gcc-4.3.2.tgz
u-boot：u-boot-1.1.6
注：编译器和u-boot 都是飞凌开发板自带的
二、 源码获得
内核源码到http://www.all.kernel.org/下载；
三、 移植步骤：
1.将Linux2.6.34.2内核源码放到工作目录文件夹下，并解压。
#tar xzvf linux2.6.36.2.tar.gz –c /
#pwd
/
# cd linux2.6.36.2
2. 修改内核源码根目录下的Makefile文件（CROSS_COMPILE =的值因个人情况而定，其他可以照做，蓝色部分为修改部分。）
#gedit Makefile
......
#SUBARCH := $(shell uname -m | sed -e s/i.86/i386/ -e s/sun4u/sparc64/ \
# -e s/arm.*/arm/ -e s/sa110/arm/ \
# -e s/s390x/s390/ -e s/parisc64/parisc/ \
# -e s/ppc.*/powerpc/ -e s/mips.*/mips/ )
......
#ARCH = $(SUBARCH)
#CROSS_COMPILE =
ARCH = arm
CROSS_COMPILE = /usr/local/arm/usr/local/arm/4.3.2/bin/arm-none-linux- gnueabi-
3添加NandFlash分区信息.
修改arch/arm/mach-s3c64xx/mach-smdk6410.c文件，添加Nand Flash的分区信息和Nand Flash的硬件信息。(蓝色字体为添加部分)
#pwd
#gedit mach-smdk6410.c //add here 注意:此处的nandflash分区信息是飞凌自带的2.6.28的内核设置,由于此处要用到uboot是飞凌的，所以分区信息也要按人家的来 添加头文件 #include #include #include #include struct mtd_partition s3c_partition_info[] = {
