## 引言

本项目旨在真正从0开始构建嵌入式linux系统，为了剖析芯片从上电开始执行第一条指令到整个系统运行，相关应用服务启动，因此不使用市面上真实的板子，基于qemu定制模拟器开发板，且不使用qemu提供的快速加载elf的文件方式，因而我们需要下载qemu源码，自己编写(或使用qemu自带的)硬件ip相关模拟代码定制属于自己的硬件板卡。本项目同步制作[博客专栏](https://blog.csdn.net/weixin_39871788/category_11180842.html)(2021.8.11:目前开始使用readthedocs构建[文档](https://quard-star-tutorial.readthedocs.io/zh_CN/latest/index.html)，与博客内容相同)，因此项目尽量保证每增加一个feature就提交一次，方便索引跟踪开发过程以方便对应到博客的具体章节。

## 环境搭建

ubuntu18.04需要使用apt安装的包:

```shell
sudo apt install ninja-build pkg-config libglib2.0-dev libpixman-1-dev libgtk-3-dev libcap-ng-dev libattr1-dev libsdl2-dev device-tree-compiler bison flex gperf intltool mtd-utils
```
