[国嵌攻略][102][内核驱动开发环境搭建]

服务器环境搭建

1.配置tftp服务器

1.1.设置tftp目录

vim /etc/xinetd.d/tftp

server_args             = -s .../tftp

disable                 = no

1.2.启动tftp服务

/etc/init.d/xinetd restart

 

2.配置nfs服务器

2.1.设置nfs目录

vim /etc/exports

.../nfs *(rw,sync,no_root_squash)

2.2.启动nfs服务

/etc/init.d/nfs restart

 

 

 

bootloader环境搭建

1.解压bootloader

tar zxvf uboot_mini2440.tar.gz

 

2.清除bootloader

cd uboot_mini2440

make distclean

 

3.配置bootloader

make mini2440_config

 

4.编译bootloader

make ARCH=arm CROSS_COMPILE=arm-linux-

 

5.下载bootloader

insmod usb.ko

./dnw u-boot.bin 30008000

 

6.设置网络环境变量

setenv ethaddr 12:34:56:78:9A:BC

setenv ipaddr 192.168.1.230

setenv serverip 192.168.1.xxx

saveenv

 

7.测试网络连接情况

ping 192.168.1.xxx

 

8.设置启动环境变量

8.1.设置tftp下载并启动内核

setenv bootcmd tftp 31000000 uImage \; bootm 31000000

8.2.设置nfs挂载根文件系统

setenv bootargs noinitrd console=ttySAC0,115200 init=/init root=/dev/nfs rw nfsroot=192.168.1.101:.../rootfs ip=192.168.1.230:192.168.1.101:192.168.1.1:255.255.255.0::eth0:off

saveenv

 

 

 

rootfs环境搭建

1.创建系统目录

mkdir rootfs

cd rootfs

mkdir bin dev etc lib mnt proc sbin sys tmp usr var

mkdir usr/bin usr/lib usr/sbin lib/modules

 

2.创建设备文件

cd dev

mknod -m 666 console c 5 1

mknod -m 666 null c 1 3

 

3.添加配置文件

tar zxvf etc.tar.gz

cp -rf etc/* rootfs/etc/

 

4.添加系统工具

4.1.解压busybox

tar zxvf busybox-1.13.3.tar.gz

4.2.清除busybox

make distclean

4.3.配置busybox

cd busybox-1.13.3

make menuconfig

busybox settings->build options->[*]build busybox as a static binary

busybox settings->build options->(arm-linux-)cross compiler prefix

busybox settings->installation options->[*]don’t use /usr

busybox settings->installation options->(.../rootfs)busybox installation prefix

4.4.编译busybox

make

4.5.安装busybox

make install

 

 

 

kernel环境搭建

1.解压kernel

tar zxvf linux-mini2440.tar.gz

 

2.清除kernel

cd linux-mini2440

make distclean

 

3.配置kernel

3.1.加载配置文件

make menuconfig ARCH=arm

load an alternate configuration file->.config->exit->save

3.2.配置文件系统

make menuconfig ARCH=arm

general setup->[ ]initial ram filesystem and ram disk

file systems->[*]network file systems->[*]root file system on nfs

 

4.编译kernel

4.1.复制mkimage工具

cp .../uboot_mini2440/tools/mkimage /bin

4.2.编译kernel

make uImage ARCH=arm CROSS_COMPILE=arm-linux-

 

5.编译kernel模块

make modules ARCH=arm CROSS_COMPILE=arm-linux-

 

6.安装kernel模块

make modules_install ARCH=arm INSTALL_MOD_PATH=.../rootfs

 

7.复制Image到tftp目录下

cp kernel/arch/arm/boot/uImage .../tftp

 

8.复制rootfs到nfs目录下

cp rootfs/* .../nfs -rf
