Tiny210v2( S5PV210 )平台下利用uboot启动远程Kernel(TFTP)以及挂载远程ROOTFS(NFS)

来源：爱go旅游网

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.arm9home.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

1. make ARCH=arm CROSS_COMPILE=arm-linux- tiny210_config

然后才是真正的编译uboot：

复制代码

1. 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

1. sudocp 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

1. sudoddiflag=dsyncoflag=dsync if=spl/tiny210-spl.bin of=/dev/sdc seek=1 2. sudoddiflag=dsyncoflag=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

1. * Networking support -> Networking options ->IP:kernel level autoconfi

guration

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

1. * File systems -> Network File System -> NFS client support

2. * File systems -> Network File System -> NFS client support for NFS ver

sion 3 或者 4

3. * 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。

复制代码

1. make uImage

下面的LOG表明uImage生成了，位于 arch/arm/boot/uImage。

复制代码

1. CHK include/linux/version.h

2. CHK include/generated/utsrelease.h

3. make[1]: `include/generated/mach-types.h' is up to date. 4. CALL scripts/checksyscalls.sh 5. CHK include/generated/compile.h 6. Kernel: arch/arm/boot/Image is ready

11. Kernel: arch/arm/boot/zImage is ready 12. UIMAGE arch/arm/boot/uImage 13. Image Name: Linux-3.0.8-TINY210V2+ 14. Created: Wed Jan 23 21:10:56 2013

19. Image arch/arm/boot/uImage is ready

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

1. 367 KBUILD_CFLAGS := -Wall -Wundef -Wstrict-prototypes -Wno-tri

graphs \\

2. 368 -fno-strict-aliasing -fno-common \\ 3. 369 -Werror-implicit-function-declaration \\ 4. 370 -Wno-format-security \\

5. 371 -fno-delete-null-pointer-checks \\ 6. 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

1. sudo apt-get install atftpdopenbsd-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：

复制代码

1. #:BOOT: TFTP service is provided primarily for booting. Most site

2. # run this only on machines acting as \"boot servers.\" 3. tftp dgram udp wait nobody /usr/sbin/tcpd /usr/sbin

/in.tftpd /srv/tftp

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。

复制代码

1. ln -s /opt/S5PV210/rootfs/usr/src/linux-3.0.8/arch/arm/boot/uImag

e /srv/tftp/uImage

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：

复制代码

1. sudo service openbsd-inetd restart

可以通过查看端口确认inetd是否真的在监听 TFTP 端口：

复制代码

1. zoulz@Seagate:/tmp$ netstat -a | greptftp

2. udp 0 0 *:tftp *:*

可以通过下面的命令测试一下 TFTP 服务是否正常工作：

复制代码

1. zoulz@Seagate:/tmp$ tftplocalhost 2. tftp> get uImage

3. Received 3578106 bytes in 0.3 seconds

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：

复制代码

1. sudo apt-get install nfs-kernel-server

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。

复制代码

1. # Example for NFSv2 and NFSv3:

2. # /srv/homes hostname1(rw,sync,no_subtree_check) hostname2(r

o,sync,no_subtree_check) 3. #

4. # Example for NFSv4:

5. # /srv/nfs4 gss/krb5i(rw,sync,fsid=0,crossmnt,no_subtree_c

heck)

6. # /srv/nfs4/homes gss/krb5i(rw,sync,no_subtree_check) 7. #

8. /opt/S5PV210/rootfs *(rw,sync,no_subtree_check,no_root_squash)

每一次修改 /etc/exports 这个文件，都需要重新启动 NFS 服务器：

复制代码

1. sudo service nfs-kernel-server restart

可以通过下面的命令测试 NFS 服务器是否设置正确：

复制代码

1. zoulz@Seagate:/tmp$ rm a b 2. zoulz@Seagate:/tmp$ mkdir /tmp/a

3. zoulz@Seagate:/tmp$ sudo mount -t nfs -o nolocklocalhost:/opt/S5PV

210/rootfs /tmp/a

4. zoulz@Seagate:/tmp$ ls /tmp/a

5. bin dev etc home lib linuxrc proc root run sbin sys tm

p usr var

6. zoulz@Seagate:/tmp$ ls /opt/S5PV210/rootfs

7. bin dev etc home lib linuxrc proc root run sbin sys tm

p usr var

也可以通过df命令查看挂载情况：

复制代码

1. zoulz@Seagate:/tmp$ df

2. Filesystem 1K-blocks Used Available Use% Mo

unted on

3. localhost:/opt/S5PV210/rootfs 1239744 36394112 045632 30% /t

mp/a

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。

复制代码

1. sudoifconfig eth0 192.168.1.5

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。

复制代码

1. setenvbaudrate 115200 2. setenvstderr serial 3. setenvstdin serial 4. setenvstdout serial 5. setenvbootdelay 3 6. setenvethact dm9000

7. setenvethaddr 00:40:5c:26:0a:5b 8. setenvgatewayip 192.168.1.1 9. setenvipaddr 192.168.1.80 10. setenvnetmask 255.255.255.0 11. setenvserverip 192.168.1.5

12. setenvbootargs root=/dev/nfsrwnfsroot=$serverip:/opt/S5PV210/root

fs,nolock,tcpip=$ipaddr console=ttySAC0,115200 ctp=1 kgdboc=ttySAC0,115200 13. setenvbootcmd \"tftp 21000000 uImage;bootm 21000000\"

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

rwnfsroot=$serverip:/opt/S5PV210/rootfs,nolock,tcp告诉内核通过NFS启动， root=/dev/nfs并非真的设备，而是一个告诉内核要通过网络取得根文件系统。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。
