移植linux-2.6.29+busybox最小系统到单板OK6410
来源：互联网 发布：微博登录网络异常 编辑：程序博客网 时间：2024/05/16 10:18
系统：ubuntu 10.04.4
单板：ok6410
编译器：arm-none-linux-gnueabi-
搭建开发环境详见ubuntu 10.04.4开发环境配置。
目标:
一.配置 编译android-2.6.29,放到OK6410上,板子串口正常输出
二.移植DM9000网卡驱动,配置内核,支持nfs挂载网络文件系统
一.配置 编译android-2.6.29,放到OK6410上,板子串口正常输出
1.获取交叉编译链 http://code.google.com/p/smp-on-qemu/downloads/list 选择arm-2009q3-67-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2并下载。然后在ubuntu下直接解压即可
2.git下载内核源码android-2.6.29
change@change:~$ mkdir android
change@change:~/android$ git clonehttps://android.googlesource.com/kernel/goldfish.git
Initialized empty Git repository in /home/change/android/goldfish/.git/

显示100%之后则表示同步完成。此时goldfish下的所有内核版本的源码都已同步完成
设定默认使用版本
进入到goldfish目录下，使用如下命令查看所有可用版本名称。
change@change:~/android$ cd goldfish/
change@change:~/android/goldfish$ git branch -a
我的系统显示如下：
* master
remotes/origin/HEAD -> origin/master
remotes/origin/android-goldfish-2.6.29
remotes/origin/android-goldfish-3.4
remotes/origin/linux-goldfish-3.0-wip
remotes/origin/master
“*”指代的当前目录下默认的版本。设定“android-goldfish-2.6.29”为默认，则可以在终端中输入如下命令：
git checkout -b android-2.6.29 origin/android-goldfish-2.6.29
-b后面的android-2.6.29只是给后面的内核源码版本起了个自己定义的名字，方便自己查看而已，也可以不定义，不定义就会使用默认名称。此时，查看goldfish下的目录即为“android-goldfinsh-2.6.29”版本的模拟器内核源码。在goldfish目录下使用如下命令进行查看当前内核版本的名称。
change@change:~/android/goldfish$ git checkout -b android-2.6.29 origin/android-goldfish-2.6.29
Checking out files: 100% (26821/26821), done.
Branch android-2.6.29 set up to track remote branch android-goldfish-2.6.29 from origin.
Switched to a new branch 'android-2.6.29'
change@change:~/android/goldfish$ git branch
* android-2.6.29
master
下载的android-2.6.29代码如下:
change@change:~/android/goldfish$ ls
arch CREDITS drivers include Kbuild MAINTAINERS net samples sound
block crypto firmware init kernel Makefile README scripts usr
COPYING Documentation fs ipc lib mm REPORTING-BUGS security virt
change@change:~/android/goldfish$
3.修改顶部Makefile：193
ARCH ?= arm
CROSS_COMPILE ?= /home/change/tools/arm-2009q3//bin/arm-none-linux-gnueabi-
4.配置
make s3c6400_defconfig
5.编译make uImage

二.移植DM9000网卡驱动,配置内核,支持nfs挂载网络文件习统
1修改arch/arm/mach-s3c6410/mach-smdk6410.c
添加代码如下:

.resource = dm9000_resources,
.dev = {
.platform_data = &dm9000_setup,
}
};
186:

2.make menuconfig

3.make uImage
change@change:~/android/goldfish$ make uImage
Image Name: Linux-2.6.29-ge3d684d-dirty
Created: Mon May 6 15:42:20 2013
Image Type: ARM Linux Kernel Image (uncompressed)
Data Size: 1413260 Bytes = 1380.14 kB = 1.35 MB
Load Address: 50008000
Entry Point: 50008000
Image arch/arm/boot/uImage is ready
change@change:~/android/goldfish$ cp arch/arm/boot/uImage /home/change/work/tftpboot/
4.设置u-boot的bootargs,通过nfs挂载文件系统
SMDK6410 # set bootargs console=ttySAC0,115200 init=/linuxrc root=/dev/nfs nfsroot=172.16.1.132:/home/change/work/rootfs_dir/fs_mini \
nolock ip=172.16.1.111:172.16.1.132:172.16.1.1:255.255.255.0::eth0:off
