在bbb上安装ubuntu系统

其他 其他 6234 人阅读 | 0 人回复 | 2017-07-25

      拿到beaglebone black板子之后，默认安装的是Angstrom系统，这个系统根分区文件系统占据eMMC中1.3GB的空间，原因是里面安装了图形界面，同时还有其他一些gcc、g++、vim等一些常用的软件都安装进去了，所以体积才会变大。由于最近想要BBB板子挂载一下宿主机的NFS，但是在做尝试时发现Angstrom原装的系统中没有NFS的客户端，还需要安装一个客户端nfs-common，但是在板子上运行opkg update更新倒是可以，可是opkg install nfs-common或者安装其他包一律无法识别，除了一些常用的的诸如vim、g++倒是能识别，即使识别了一样还是不能安装，而在网站上我又没有找到nfs-common的源码包，倒是找到了nfs-uti**这么一个替代源码包，可是手动安装一个软件带来的困难是，它需要依赖一些其他的库，那么又要安装其他的库，即为了安装A，得先安装好B，为了安装B，又得先安装C.........无奈，只好选择换系统，最后选择了自己最喜欢的ubuntu。

        要在BBB板子上安装一个系统可以有三种方法，1）通过烧写一个预编译好的镜像文件到SD卡，插到板子上，将eMMC烧写即可。2）通过网络安装。3）完全手动安装，这种方式主要是u-boot、内核、根文件系统都是自己编译或者做，最后组装成系统，对于学习系统启动原理很有帮助，有点Linux from scratch的味道。后面两种方法限于时间没有尝试过，ubuntu的安装是第一种方法

将镜像文件链接成loop设备，loop 设备是一种伪设备(pseudo-device)，或者也可以说是仿真设备。它能使我们像块设备一样访问一个文件，在使用之前，一个 loop 设备必须要和一个文件（指的就是*.img文件）进行连接。这种结合方式给用户提供了一个替代块特殊文件的接口。因此，如果这个文件包含有一个完整的文件系统，那么这个文件就可以像一个磁盘设备一样被 mount 起来。如下所示，
  1. <font size="3" color="#000000">    zhouyu@zhouyu-virtual-machine:~/zystore$ ls  
  2.     BBB-eMMC-flasher-ubuntu-14.04-console-armhf-2014-08-13-2gb.img  
  3.     fat  
  4.     linux-3.12.10-ti2013.12.01  
  5.     lost+found  
  6.     rootfs  
  7.     u-boot-2013.10-ti2013.12.01  
  8.     ubuntu-precise-12.04-LTS  
  9.     zhouyu@zhouyu-virtual-machine:~/zystore$ sudo kpartx -a -v BBB-eMMC-flasher-ubuntu-14.04-console-armhf-2014-08-13-2gb.img   
  10.     [sudo] password for zhouyu:   
  11.     add map loop0p1 (252:0): 0 196608 linear /dev/loop0 2048  
  12.     add map loop0p2 (252:1): 0 3282944 linear /dev/loop0 198656</font>
复制代码
上述可以看出，和.img文件进行连接之后，loop0设备出现了两个分区。接下来将loop设备的两个分区分别挂载回原来的文件系统，挂载到本目录下的fat和rootfs文件夹。.img文件本身是原来文件系统的文件，将其和loop设备链接之后，又将loop设备挂载回原来的文件系统，于是loop名字由此而来。其中用到了一个工具kpartx，这个工具我觉得其实就相当于windows下面的虚拟光驱的作用，虚拟光驱也是将一个镜像文件和虚拟设备进行连接。
  1. <font size="3" color="#000000">    zhouyu@zhouyu-virtual-machine:~/zystore$ sudo mount /dev/mapper/loop0p1 fat/  
  2.     zhouyu@zhouyu-virtual-machine:~/zystore$ sudo mount /dev/mapper/loop0p2 rootfs/</font>
复制代码
查看.img文件的内容
  1. <font size="3" color="#000000">    zhouyu@zhouyu-virtual-machine:~/zystore/fat$ ls  
  2.     App          Drivers      nfs-uEnv.txt  scripts     uEnv.txt  
  3.     autorun.inf  LICENSE.txt  README.htm    START.htm  
  4.     Docs         MLO          README.md     u-boot.img  
  5.     zhouyu@zhouyu-virtual-machine:~/zystore/fat$ cd ../rootfs/  
  6.     zhouyu@zhouyu-virtual-machine:~/zystore/rootfs$ ls  
  7.     bin   dev  home  lost+found  mnt  proc  run   srv  tmp  var  
  8.     boot  etc  lib   media       opt  root  sbin  sys  usr  </font>
复制代码
接下来将.img文件原封不动的搬到SD卡里面
  1. <font size="3" color="#000000">sudo dd if=*.img of=/dev/sdX bs=1M</font>
复制代码
dd命令用处多多，诸如这种将镜像文件烧写到SD卡，以及一些硬盘对拷、硬盘的备份和还原都非常好，感觉就像windows下面的Ghost程序。它基本上是把一个存储介质里面的数据原封不动的搬过去，不同于我们通常的文件复制哦。所以使用这个命令不再需要自己制作SD卡，进行分区，然后拷贝文件。


这一步完成之后。记得先将文件系统卸载，再接着删除虚拟设备（也就是loop设备）。
  1. <font size="3" color="#000000">  sudo umount fat/  
  2.     sudo umount rootfs/  
  3.     sudo kpartx -d *.img </font>
复制代码
OK，一张ubuntu的SD启动卡只做好了。接下来按照流程操作就好。

关于镜像文件
         关于安装系统方面的镜像有两种版本，一种版本是做到SD卡里面用于烧写eMMC以进行重新安装系统，另一种版本是做到SD卡里面用于从SD卡启动系统。其实两本版本的镜像差不太多。第一种版本的SD卡插到板子上按住boot键上电启动后，也是和第二种版本一样先从SD卡启动，然后接着有一个用于更新eMMC的进程被初始化，这个进程的工作，就是讲SD卡里面带的MOL、u-boot.img、根文件系统（包含内核）分别复制到eMMC的启动分区和根分区，从而更新系统。这些进行系统更新的脚本文件可能放在根文件系统的/opt/scripts/目录下，也有可能是在/usr/bin/目录下，不同的人制作的可能就不同。
         以下是将一个用于更新eMMC的SD卡插到板子上上电后，从串口得到的输出信息：
