0. 准备工作
1. 编译uboot
2. 将uboot写入SD卡
3. 编译kernel，设置其可以通过NFS挂载根文件系统
4. 开发环境安装TFTP服务器
5. 开发环境安装NFS服务器
6. 目标环境设置uboot参数
7. 制作根文件系统（optional）。
8. 完整的启动LOG。 有几位网友发信问我uboot挂载文件系统的方法，其实这个部分也不是我原创的，大部分都是参考其他网友的方法，现在将我的手顺记录下来，希望对大家有所帮助。
整体思路大概是这样：
* 将uboot烧写到SD卡。
* 从SD卡启动系统，SD卡中的uboot通过TFTP协议将远程的的Kernel下载到内存中。
* uboot将内核参数设定为ROOT分区为远程的NFS-SERVER共享的一个目录，并JUMP到内核的START ADDRESS。
* kernel自解压，并JUMP 到解压后的新的内核START ADDRESS，内核正常启动。
* 最后通过内核通过uboot设置的ROOTFS参数得知根文件系统在远程，并通过NFS挂载ROOTFS。
* 根文件系统挂载完了以后，就会去执行init程序， init程序被uboot指定为 /linuxrc。
我的开发环境是 ubunto 12.04LTS。
目标系统的内核是 3.0.8 ，源代码位于 /opt/S5PV210/rootfs/usr/src/linux-3.0.8。
uboot的源代码位于 /opt/S5PV210/rootfs/usr/src/opencsbc-u-boot。
目标环境的根文件系统位于 /opt/S5PV210/rootfs。
交叉编译器位于 /opt/linaro-gcc473-eglibc216-armv7a-neon。0. 准备工作 编译uboot和linux内核都需要使用到交叉编译器，所以需要确保shell 的PATH 环境中包含了你的交叉编译器的路径。
比如我的PATH为：(通过export查看) declare -x PATH="/usr/lib/lightdm/lightdm:/opt/linaro-gcc473-eglibc216-armv7a-neon/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games"
这样，就可以直接查找到 arm-linux-gcc 这条命令了，不许要输入 arm-linux-gcc 的绝对路径。1. 编译uboot uboot来自于kasim修改的uboot，原帖在http://www.aiothome.net/read.php?tid-16001.html。
可以通过 https://gitorious.org/opencsbc/u-boot/trees/mini210_linaro-2012.11-stable 右边的 download mini210_linaro-2012.11-stable as tar.gz 这个按钮获取到打包的源代码。
将源代码下载下来以后，解压到某一个目录，我机器上是位于 /opt/S5PV210/rootfs/usr/src/opencsbc-u-boot 这个目录。进入到这个目录。
首先配置uboot是针对 tiny210 环境的。 tiny210v2 也是使用的这个配置项：复制代码- make ARCH=arm CROSS_COMPILE=arm-linux- tiny210_config
|
然后才是真正的编译uboot：复制代码- make ARCH=arm CROSS_COMPILE=arm-linux- all spl
|
编译完成以后，就可以看到uboot的二进制文件 spl/tiny210-spl.bin 和 uboot.bin。
另外还有一个用于制作 uImage 的工具 tool/mkimage。为了方便，把这个文件拷贝到 /usr/bin：复制代码- sudo cp tool/mkimage /usr/bin/
|
2. 将uboot写入SD卡 注意，这部需要特别留心，别因为误写入，把你的硬盘给弄坏了。
注意，SD卡的内容最好备份好。
将SD卡放到读卡器里面，并将SD卡读卡器接入开发环境，在我的环境中， SD卡会被识别为 /dev/sdc。
通过下面的命令将uboot写入SD卡，保证这个SD卡可以启动。复制代码- sudo dd iflag=dsync oflag=dsync if=spl/tiny210-spl.bin of=/dev/sdc seek=1
- sudo dd iflag=dsync oflag=dsync if=u-boot.bin of=/dev/sdc seek=49
|
如果怕写入不同步，可以再执行一下 sync 这个命令，保证cache都写入到磁盘中。
到此为止，就可以通过SD卡启动uboot了。3. 编译kernel，设置其可以通过NFS挂载根文件系统 光盘中带的内核，默认不支持从NFS挂载ROOTFS。需要重新配置并编译内核。
在/opt/S5PV210/rootfs/usr/src/linux-3.0.8目录下，通过 make menuconfig 启动ncurses图形配置界面。
下面几个个内核配置项，必须选中。复制代码- * Networking support -> Networking options ->IP:kernel level autoconfiguration
|
注意，这个选项下面的 IP:DHCP support / IP:BOOTP support / IP:RARP aupport 不能选。
因为我的开发环境中没有安装 DHCP server。开发板的 IP 是在内核启动参数中指定的。复制代码- * File systems -> Network File System -> NFS client support
- * File systems -> Network File System -> NFS client support for NFS version 3 或者 4
- * File systems -> Network File System -> Root file system on NFS
|
将退出配置，并保存。
执行下面的命令生成 uImage 内核镜像文件，这个过程其实是先生成了 zImage ，然后调用了刚才uboot的那个 mkimage 生成 uImage。 下面的LOG表明 uImage 生成了，位于 arch/arm/boot/uImage。复制代码- CHK include/linux/version.h
- CHK include/generated/utsrelease.h
- make[1]: `include/generated/mach-types.h' is up to date.

|
编译内核的时候，如果你使用的是 4.6以后的 gcc，需要在Makefile中添加 -mno-unaligned-access 给 KBUILD_CFLAGS 防止内核解压完以后启动不了。复制代码- 367 KBUILD_CFLAGS := -Wall -Wundef -Wstrict-prototypes -Wno-trigraphs \
- 368 -fno-strict-aliasing -fno-common \
- 369 -Werror-implicit-function-declaration \
- 370 -Wno-format-security \
- 371 -fno-delete-null-pointer-checks \
- 372 -mno-unaligned-access
|
如果你生成的内核有问题，可以试一试我的内核配置文件 my_config。4. 开发环境安装TFTP服务器 接下来，就是要在开发环境上安装 TFTP 服务器，使开发板可以通过TFTP协议下载 uImage 这个文件。
在 ubuntu 下，可以通过下面的命令安装 TFTP 服务器，这个服务是通过 inet 监听的。复制代码- sudo apt-get install atftpd openbsd-inetd
|
安装完以后，需要配置一下 TFTP 的默认查找目录，我将其设定为 /srv/tftp：
确认 /etc/inetd.conf 文件中有如下一行：[code] #:BOOT: TFTP service is provided primarily for booting. Most sites
# run this only on machines acting as "boot servers."
tftp dgram udp wait nobody /usr/sbin/tcpd /usr/sbin/in.tftpd /srv/tftp[/code]
因为 TFTP 服务主要是给 uboot 提供内核镜像文件，为了避免每次内核编译完以后都拷贝到 /srv/tftp 目录中，
我在 /srv/tftp 目录中，建立了一个 符号文件，指向 /opt/S5PV210/rootfs/usr/src/linux-3.0.8/arch/arm/boot/uImage。[code] ln -s /opt/S5PV210/rootfs/usr/src/linux-3.0.8/arch/arm/boot/uImage /srv/tftp/uImage[/code]
可以通过下面的命令重启 inetd ，保证这个 supper服务器能够监听 TFTP 端口：[code] sudo service openbsd-inetd restart[/code]
可以通过 查看端口确认 inetd 是否真的在监听 TFTP 端口：[code] zoulz@Seagate:/tmp$ netstat -a | grep tftp
udp 0 0 *:tftp *:* [/code]
可以通过下面的命令测试一下 TFTP 服务是否正常工作：[code] zoulz@Seagate:/tmp$ tftp localhost
tftp> get uImage
Received 3578106 bytes in 0.3 seconds[/code]
5. 开发环境安装NFS服务器
接下来是配置 NFS 服务器，用于开发板上内核启动以后挂载开发环境的ROOTFS。
通过下面的命令安装 nfs 服务器：[code] sudo apt-get install nfs-kernel-server [/code]
安装完成以后，还需要修改 /etc/exports 文件，设置 NFS 共享的文件目录。我们需要将 /opt/S5PV210/rootfs 设置为NFS共享目录。[code] # Example for NFSv2 and NFSv3:
# /srv/homes hostname1(rw,sync,no_subtree_check) hostname2(ro,sync,no_subtree_check)
#
# Example for NFSv4:
# /srv/nfs4 gss/krb5i(rw,sync,fsid=0,crossmnt,no_subtree_check)
# /srv/nfs4/homes gss/krb5i(rw,sync,no_subtree_check)
#
/opt/S5PV210/rootfs *(rw,sync,no_subtree_check,no_root_squash)[/code]
每一次修改 /etc/exports 这个文件，都需要重新启动 NFS 服务器：[code] sudo service nfs-kernel-server restart[/code]
可以通过下面的命令测试 NFS 服务器是否设置正确：[code] zoulz@Seagate:/tmp$ rm a b
zoulz@Seagate:/tmp$ mkdir /tmp/a
zoulz@Seagate:/tmp$ sudo mount -t nfs -o nolock localhost:/opt/S5PV210/rootfs /tmp/a
zoulz@Seagate:/tmp$ ls /tmp/a
bin dev etc home lib linuxrc proc root run sbin sys tmp usr var
zoulz@Seagate:/tmp$ ls /opt/S5PV210/rootfs
bin dev etc home lib linuxrc proc root run sbin sys tmp usr var[/code]
也可以通过 df 命令查看挂载情况：[code] zoulz@Seagate:/tmp$ df
Filesystem 1K-blocks Used Available Use% Mounted on
localhost:/opt/S5PV210/rootfs 125439744 36394112 89045632 30% /tmp/a[/code]
6. 目标环境设置uboot参数 注意： ubuntu 的 network manager， 如果开发板和开发环境的PC直连的话， 每次开发板哪掉电，开发环境PC会检测为网络未链接，
nm 就会将已经设置好的网卡 down 掉。这在开发板reset的时候特别讨厌，你得每次都重新去设置PC的IP地址。 因此我将桌面右上角的network manager的 Enable Networking 设置为 不选中，禁止 network manager 去管理网络。
然后在终端里通过下面的命令，将网卡设置为 192.168.1.5，这样每次开发板reset就不用再设置开发环境PC的IP了。[code] sudo ifconfig eth0 192.168.1.5[/code]
当然，如果你的开发板和开发环境PC都是链接到路由器或者HUB，就没有这个烦恼。
现在所有的东西都准备好了。将SD卡插入开发板，并调整switch，设置从SD卡启动系统。
正常情况下，就应该能够看到 uboot 的界面了（ FriendlyLEG-TINY210 ）了：
在 uboot 的shell中，通过 setenv 命令设置相关参数。[code] setenv baudrate 115200
setenv stderr serial
setenv stdin serial
setenv stdout serial
setenv bootdelay 3
setenv ethact dm9000
setenv ethaddr 00:40:5c:26:0a:5b
setenv gatewayip 192.168.1.1
setenv ipaddr 192.168.1.80
setenv netmask 255.255.255.0
setenv serverip 192.168.1.5
setenv bootargs root=/dev/nfs rw nfsroot=$serverip:/opt/S5PV210/rootfs,nolock,tcp ip=$ipaddr console=ttySAC0,115200 ctp=1 kgdboc=ttySAC0,115200
setenv bootcmd "tftp 21000000 uImage;bootm 21000000"[/code]
bootcmd参数中的 tftp 21000000 用于： 通过 TFTP 命令，将 192.168.1.5 的 /srv/tftp/uImage 下载到 0x21000000 这个位置。
bootcmd参数中的 bootm 21000000 用于： uboot将CPU执行权地交给 0x21000000 这个位置的内核镜像，也就是启动内核。
bootargs参数用于设置内核的启动参数，其中 root=/dev/fs rw nfsroot=$serverip:/opt/S5PV210/rootfs,nolock,tcp 告诉内核通过NFS启动，
根文件系统位于 192.168.1.5:/opt/S5PV210/rootfs
NFS 的参数为 nolock,tcp ，用于防止 udp 不稳定导致 NFS 读取NG 的情况。
ip=$ipaddr 设置开发板自身的ip地址为 192.168.1.80 。
通过 saveenv 将上面的参数写入到 SD卡中，这样就不用每次reset都输入一遍uboot的参数了。
通过 boot 命令，将CPU 执行权专递给 Kernel。7. 制作根文件系统（optional）。 待续，busybox + toolchain。
8. 完整的启动LOG。[code]root@Seagate:/tmp# minicom /dev/ttyS0
