RK 平台安装 ubuntu 系统

<h1 id="一简介">一、简介</h1>
<p>之前有介绍到 ARM 平台移植 ubuntu 的操作流程，在 RK 系列的平台同样适用，所以这里就不介绍怎么一步步的去对 ubuntu 进行移植，而是怎么将移植的过程编写成脚本，这样便可以在 SDK 中通过一行命令即可生成 rootfs.img 镜像，管理起来也也比较方便，需要裁剪摸个工具时也很便捷。</p>
<p>可能没有进行过系统移植的小伙伴看着比较困难，建议先从前面的笔记看着来，在看这篇笔记就会发现很简单，也可以理解 RK 平台的 SDK 是怎么回事。</p>
<h1 id="二准备材料">二、准备材料</h1>
<p>我使用的芯片是RK3588，小伙伴可以根据自己的情况选择开发版。<br>
开发环境：VMware<br>
操作系统：ubuntu<br>
开发版：RK3588</p>
<h1 id="三debian-目录">三、Debian 目录</h1>
<p>因为 RK 平台的 SDK 中是已经支持 Debian 的，所以我们可以根据 Debian 系统的编译方式来模仿 ubuntu 脚本的编写，这样大大降低了操作的难度，还可以明白系统移植是的流程。</p>

<p><strong>注意：</strong> 以上这些文件都是与外设相关的，也就是解决安装第三方系统后与硬件环境不兼容问题的关键，这里应该会有小伙伴和一样好奇，这里面的文件是怎么来的，我也没仔细去研究过，但是一定是从官方提供的 external 中编程出来的。</p>
<ul>
<li>配置文件、 .so、.a 文件：可以与 buildroot 进行对比，没猜错的话，一定能在 buildroot 编译输出的目录中能找到。</li>
<li>deb 工具包：这里就不用过多的介绍了，看我之前的笔记便可明白</li>
<li>ubuntu-build-service/packages 目录下的 deb：这里需要注意一下，这里面的包是编译时宿主机必须具备的环境，并不是厂商提供的，而是从网上下载的，路径如下<pre><code>live-build_*.deb来源https://mirrors.ustc.edu.cn/debian/pool/main/l/live-build/
debootstrap_*.deb来源https://mirrors.ustc.edu.cn/debian/pool/main/d/debootstrap/
</code></pre>
当然也是可以通过 apt 命令进行安装。</li>
</ul>
<p>了解这些基本信息后，变可以仿照编写一个 ubuntu 编译的脚本。这个工程量还是有点大的，难度虽然不大，但是也是一个比较费时的事，不过好在我在网上找了一下，找到了野火已经编写好了，这里我们就不用重复造轮子了，在这里感谢野火的无私奉献。</p>

</code></pre>
<p>通过挂载 proc、sysfs 和 /dev 是为了构建一个隔离的运行环境，让 chroot 内的程序以为自己运行在一个独立的系统环境中，而不是主机的实际系统环境。</p>
<ul>
<li>挂载 /proc 文件系统： /proc 是一个虚拟文件系统，提供了关于系统内核和进程的信息。</li>
<li>挂载 /sys 文件系统： /sys 文件系统包含了关于系统硬件、设备和驱动程序的信息。</li>
<li>绑定挂载 /dev 目录： /dev 目录包含了设备文件，用于访问系统的各种硬件设备。</li>

<p><strong>注意：</strong> 关于上面提到平台相关的 deb 是怎么来的，在文章的开头变介绍了，这里就不过多描述。可以多参看一下 buildroot 的操作过程，熟悉后，基本可以轻松了解整个环节</p>

<p>将会发现整个打包的过程也比较简单，前面也有笔记进行介绍。</p>
<h2 id="八总结">八、总结</h2>
<p>到此我们对于 ARM 环境中安装系统的操作基本结束了，看到这里都没什么问题的小伙伴也彻底掌握了移植的流程和移植过程中的问题处理。剩下的就是时间问题。</p>
<p>给大家的建议也很简单，在学习的时候，一定要多练习，有时候脑子是明白了，一操作感觉又啥都不会，在练习的过程中，可以帮助自己理解。</p>
<p>这里我们再次感谢野火的无私奉献，他们的脚本，帮助我们快速学习 ubuntu 环境的安装，大大省去了自己编写脚本的过程，特别像我们这样对编写 shell 脚本熟练不是很高的小伙伴，话的时间会更久。</p>
<p>最后便可以学习 android 和 鸿蒙系统的安装，由于我也在学习的过程中，还要自己的工作要处理，所以后面的笔记出的会慢一些。也欢迎大家一起加入学习的队伍中来，相互分型，共同加快学习的速度。</p>
