转：Linux-2.6.16 For AT91RM9200开发过程
时间：2006-08-08 来源：lengxb
1、安装
从 www.kernel.org 上下载Linux2.6.16版的kernel，解压到 /usr/src/arm/linux-2.6.16
从http://maxim.org.za/AT91RM9200/2.6/ 上下载针对rm9200的补丁，文件名：2.6.16-at91.patch.gz，复制到 /usr/src/arm/linux-2.6.16，然后在命令行界面中执行 zcat 2.6.16-at91.patch.gz |patch -p1
从http://www.aleph1.co.uk/cgi-bin/viewcvs.cgi/yaffs2.tar.gz?view=tar下载YAFFS2补丁 yaffs2.tar.gz 解压缩后到文件目录下运行 sh patch-ker.sh ../linux-2.6.16 把YAFF2加到内核中去;
下载GCC编译器，文件名：arm-linux-gcc-3.4.1.tar.bz2，解压到 /usr/local/arm/3.4.1
2、修改
打开内核原代码根目录下的Makefile，找到如下两行：
ARCH ?=$(SUBARCH)
CROSS_COMPILE ?=
修改为：
ARCH ?=arm
CROSS_COMPILE ?=/usr/local/arm/3.4.1/bin/arm-linux-
3、编译内核
执行如下命令：
make at91rm9200dk_defconfig
make menuconfig
改 Boot options 选项下的 Z-BOOT-ROM-TEXT 为0x21000000
Z-BOOT-ROM-BSS 为0x21100000
make zImage
4、运行
在开发板上运行u-boot后
tftp 21000000 zImage
tftp 21100000 Ramdisk
go 21000000
运行过程:
NJZD-Boot> tftp 21000000 zImage
