mini2440 uboot使用nfs方式引导内核，文件系统
成于坚持，败于止步
看了一段时间的u-boot了，到今天才真正完全实现u-boot引导内核和文件系统，顺利开机，在此记录完整过程
1、首先如果你u-boot还没有一直也没有关系，这里上传了一个已经移植好的u-boot，版本问2010.03，多谢tekkaman分享的这个源码
分享下载地址：u-boot-2010.03
编译uboot的过程就不在多说了，解压到你希望的目录下执行make，当时事前安装好交叉编译工具，这个相信大家都会
编译完成之后生成uboot.bin文件，使用mini2440自带的USB下载方式下载到开发板，选择v命令下载即可
开机界面如下，你的可能不完全显示的一样，这是经过我修改的

然后就要开始考虑怎么下载内核了，不错，要引导内核首先你需要把内核下载的你的内存中，那么首先配置好你的下载环境是最重要的
2、linux nfs安装与配置
在ubuntu下安装、配置nfs服务的步骤如下：
安装nfs
Ubuntu上默认是没有安装nfs服务器的，因此我们首先安装nfs服务器端：
$sudo apt-get install nfs-kernel-server
在一些文档中，提出还需要使用apt-get来手动安装nfs的客户端nfs-common，以及端口映射器portmap，但其实这是没有必要的，因为在安装nfs-kernel-server时，apt会自动为我们把它们安装好。
配置/etc/exports
nfs允许挂载的目录及权限在文件/etc/exports中进行了定义。
例如，我们要将根目录下的rootfs目录共享出来，那么我们需要在/etc/exports文件末尾添加如下一行：
/rootfs *(rw,sync,no_root_squash)
其中： /rootfs是要共享的目录，*代表允许所有的网络段访问，rw是可读写权限,sync是资料同步写入内存和硬盘，no_root_squash是nfs客户端分享目录使用者的权限，如果客户端使用的是root用户，那么对于该共享目录而言，该客户端就具有root权限。
nfs的安装如果大家还有疑问网上可以多查查
接下就要配置pc端和我们开发板端的ip等，以达到我们使用nfs这种方式下载image的目的
从新启动nfs
/etc/init.d/nfs-kernel-server restart
挂载方法：
mount 192.168.1.103:/root/tftpboot /test
嵌入式要mount 的时候 使用
mount -o nolock 192.168.1.103:/root/tftpboot /mnt/net
3、配置开发板ip和主机ip
我的配置参数：
开发板ip：192.168.1.102
主机ip(pc端ip)：192.168.1.103
uboot启动起来的使用printenv查看默认参数，包括开发板ip、server ip，还有其他一些启动参数
- [u-boot@MINI2440]# printenv
- bootdelay=5
- baudrate=115200
- ethaddr=08:08:11:18:12:27
- netmask=255.255.255.0
- tekkaman=bmp d 70000
- stdin=serial
- stdout=serial
- stderr=serial
- ethact=dm9000
- ipaddr=192.168.1.102
- serverip=192.168.1.103
- gatewayip=192.168.1.1
- bootcmd=nfs 0x30008000 192.168.1.103:/root/tftpboot/w35_image.img ;bootm 30008000
- bootargs=root=/dev/nfs rw nfsroot=192.168.1.103:/root/tftpboot/rootfs ip=192.168.1.102:192.168.1.1::255.255.255.0 console=ttySAC0,115200 init=/linuxrc mem=64M
- Environment size: 460/131068 bytes
- [u-boot@MINI2440]#
上面打印出来的参数请参照设置，特别是以下说到的几个参数格外小心，他们直接关系到你的image是否可以成功下载，成功被引导，文件系统是否成功挂载并启动
其实为了使用nfs而设定的参数为以下以下几个：ipaddr（开发板ip）
serverip（pc端作为服务器的ip）
gatewayip（使主机ip和开发板ip在同一个网段内）
bootcmd用于启动时下载image到指定的内存地址，同时使用bootm命令引导内核启动
bootargs 用于使用nfs方式挂载我们创建好的文件系统
其他参数从字面大家也可以理解，设置方法很简单，举例说明，设置bootcmd的方法
setenv bootcmd 'nfs 0x30008000 192.168.1.103:/root/tftpboot/w35_image.img \;bootm 30008000'
其他设置方法依次类推，值得注意的是：设置完成必须保持到内存，下一次启动才会生效，使用saveenv命令
例如：
setenv bootargs "mem=64M noinitrd root=/dev/nfs rw nfsroot=192.168.10.105:/opt/rootfs_qtopia_qt4 ip=192.168.10.210:192.168.10.1: :255.255.255.0 console=ttySAC0,115200 init=/linuxrc"
setenv bootcmd "nfs 0x30008000 192.168.10.105:/opt/nfs/uImage;bootm"
setenv ipaddr 192.168.10.210
setenv gatewayip 192.168.10.1
setenv serverip 192.168.10.105
setenv bootcmd "tftpboot 0x30008000 uImage;bootm"
4、如何实现使用nfs下载image到指定内存
首先需要制作能被u-boot直接引导的内核image，通常，kernel的启动需要u-boot提供一些参数信息，比如ramdisk在RAM中的地址。经过编译后的u-boot在根目录下的tools目录中，会有个叫做mkimage的工具，他可以给zImage添加一个header，也就是说使得通常我们编译的内核zImage添加一个数据头信息部分，我们把添加头后的image通常叫uImage，uImage是可以被u-boot直接引导的内核镜像。
mkimage工具的使用介绍如下：
使用: 中括号括起来的是可选的
mkimage [-x] -A arch -O os -T type -C comp -a addr -e ep -n name -d data_file[:data_file...] image
选项：
-A：set architecture to 'arch' //用于指定CPU类型，比如ARM
-O：set operating system to 'os' //用于指定操作系统，比如Linux
-T：set image type to 'type' //用于指定image类型，比如Kernel
-C：set compression type 'comp' //指定压缩类型
-a：set load address to 'addr' (hex) //指定image的载入地址
-e：set entry point to 'ep' (hex) //内核的入口地址，一般为image的载入地址+0x40（信息头的大小）
-n：set image name to 'name' //image在头结构中的命名
-d：use image data from 'datafile' //无头信息的image文件名
-x：set XIP (execute in place) //设置执行位置
先将u-boot下的tools中的mkimage复制到主机的/usr/local/bin目录下，这样就可以在主机的任何目录下使用该工具了。
首先请确认你的uboot配置信息是否与我上面说到的一致，很重中，决定成败
现在我们进入kernel生成目录(一般是arch/arm/boot目录)，然后执行如下命令，就会在该目录下生成一个uImage.img的镜像文件，把他复制到你的nfs配置好的目录下，我的是/root/tftpboot，这就是我们所说的uImage。当然你现在不想编译内核也没有关系，使用mini2440自带的image，我的是zImage_W35，打开终端，现操作如下：
- root@ubuntu:~/tftpboot# ls
- file rootfs u-boot.bin uImage zImage_W35
- root@ubuntu:~/tftpboot# mkimage -n 'mini2440_linux' -A arm -O linux -T kernel -C none -a 0x30008000 -e 0x30008040 -d zImage_W35 w35_image.img

- file rootfs u-boot.bin uImage w35_image.img zImage_W35

接下来你可以重启开发板看结果了

下一步就开始创建文件系统，并挂载文件系统
5、制作nfs启动的根文件系统
首先请确认你的uboot配置信息是否与我上面说到的一致，很重中，决定成败
再次检查配置服务器nfs路径
vi /etc/exports
/root/tftpboot *(rw,sync,no_root_squash)
其中/root/tftpboot：允许开发板或其他计算机访问的目录，这里允许所有客户端访问
r'w：文件系统可读可写，
sync：同步写磁盘（async：资料会先暂存于内存当中，而非直接写入磁盘）
创建文件系统需要使用busybox，另外，文件系统etc目录下需要不少的配置，这里打包好供大家下载
下载busybox，分享下载地址：busybox1.3.3
ect目录脚本文件，分享下载地址：etc.tar
下载后，放在linux下的一个新建的目录里面。
接下来，创建根文件系统目录
在nfs服务器根目录：/root/tftpboot下，创建rootfs目录，以及根文件系统的各个目录。
- [root@www tftpboot]# mkdir rootfs
- [root@www tftpboot]# cd rootfs
- [root@www rootfs]# mkdir bin dev etc lib proc sbin sys usr mnt tmp var
- [root@www rootfs]# mkdir usr/bin usr/lib usr/sbin lib/modules
- [root@www rootfs]# cd dev/
- [root@www dev]# mknod -m 666 console c 5 1
- [root@www dev]# mknod -m 666 null c 1 3
- [root@www 4-3-2]# tar -xvz -f etc.tar.gz -C /root/tftpboot/rootfs
- [root@www 4-3-2]# ls /root/tftpboot/rootfs/etc/
- fstab init.d inittab profile
到内核根目录下，首先执行命令：
make modules ARCH=arm CROSS_COMPILE=arm-linux-
编译完成，接着执行命令：
make modules_install ARCH=arm INSTALL_MOD_PATH=/root/tftpboot/rootfs
最后到下面路径查看是否安装成功
- root@ubuntu:~# cd tftpboot/rootfs/lib/modules/
- root@ubuntu:~/tftpboot/rootfs/lib/modules# ls
- 2.6.32.2
- root@ubuntu:~/tftpboot/rootfs/lib/modules#
紧接就是编译busybox了
6、busybox配置，编译
到busybox的根目录下执行make menuconfig
进入图形化配置界面后：
1）、进入"Busybox Settings"-->"Build Options "，选中“Build Busybox as a static binary”（直接按键盘空格键到“*”）。注意：这里是静态链接。
2）、同时在“Build Busybox as a static binary”同一个页面的下面“ Cross Compiler prefix”，按键盘Enter键进入，然后输入：“arm-linux-” ，这时出现如下的图示：
3）、进入"Busybox Settings"-->"Installation Options"，选中“Don‘t use /user”（这是为了不将busybox安装在/usr/sbin目录下）；同时，在同一个页面下的“ BusyBox installation prefix ”添加安装路径：“/nfsroot/rootfs”，如下图所示：
编译和安装busybox，首先执行：
make ARCH=arm CROSS_COMPILE=arm-linux-
编译完成之后运行：
make install
最后检查busybox是否安装好，具体方法为：查看/nfsroot/rootfs/sbin目录下是否有init存在。注意：如果init不存在说明busybox没有安装好，那么根文件系统是不能用的，这个时候，可以换个busybox试试
- root@ubuntu:~/tftpboot/rootfs/sbin# ls
- adjtimex crond fbset fsck.minix ifconfig insmod lpd mkswap raidautorun route slattach switch_root vconfig
- arp depmod fbsplash getty ifdown klogd lsmod modprobe rdate runlevel start-stop-daemon sysctl watchdog

- chroot fakeidentd fsck hwclock init losetup mkfs.minix poweroff rmmod setlogcons swapon udhcpd
- root@ubuntu:~/tftpboot/rootfs/sbin#
到这了内核image和文件系统都已经制作完毕，内核image名称w35_image.img在/root/tftpboot/目录下，文件系统在/root/tftpboot/rootfs目录下，现在你可以重新启动你的开发板了
