MQ-D1S Buildroot external tree
这个Git仓库专门支持全志在线 RV64 的平台。这个是针对 芒果PI MQ 开发板专门支持的 BR2_EXTERNAL 外部扩展支持。
快速开始
环境配置
为了使用 Buildroot，您需要在您的工作站上安装 Linux 发行版。 任何最新的 Linux 发行版（Ubuntu、Debian、Fedora、Redhat、OpenSuse 等）都可以正常工作。
但是你需要安装一些必要软件包至您的Linux工作站才可以使用Buildroot manual System requirements section. 对于 Debian/Ubuntu发行版系统，需要参考下述命令安装列出来的软件包。
$ sudo apt install debianutils sed make binutils build-essential gcc g++ bash patch gzip bzip2 perl tar cpio unzip rsync file bc git
获取代码
这个 BR2_EXTERNAL会配合着最新的LTS版本一起使用，所以版本会随着 上游的更新而建立新的分支进行更新，目前Buildroot最新 BR2_EXTERNAL最新LTS版本是 2021-02 。
首先我们获取 buildroot最新lts版本源码。
使用git clone
$ git clone https://github.com/100askTeam/buildroot_aw-ol.git buildroot
获取buildroot源码后，可以单独获取 芒果PI MQ 的 BR2_EXTERNAL 源码。
$ git clone -b main https://github.com/100askTeam/buildroot-external-mq.git
获取完成后，可以看到 一个 buildroot目录和一个 buildroot-external-mq目录。
配置并构建
首先进入到buildroot目录
$ cd buildroot/
接下来执行配置命令，来使用 mq_core_defconfig配置文件进行配置。
buildrot/ $ make BR2_EXTERNAL=../buildroot-external-mq mq_core_defconfig
指定配置文件后，可以使用 make menuconfig 命令来增加自己需要的包。
增加完成软件包后，就可以直接执行 make 命令开始编译了。
buildroot/ $ make
编译时会自动下载所需的软件包，进行配置编译最后打包成一个完成的系统镜像，整个时间受网络环境而定，一般情况下 只需要60分钟。
烧写并启动系统
编译完成后，会生成一个sdcard.img 系统镜像，镜像文件存放在 output/images/目录下。

执行如下命令讲镜像烧录进 tf卡即可，注意 /dev/sdX sdX 指的是tf卡设备的主分区。
或者可以使用 wind32diskimage进行烧写。
buildroot/ $ dd if=output/images/sdcard.img of=/dev/sdX bs=1M
烧写完成后，将卡插入至开发板，连接电源线，设置为 tf卡启动，即可启动开发板，之后连接串口，等待进入终端命令行，系统默认的登录用户名是 root 。
注意这个只是最小系统，大家想做什么二次开发 直接在上面进行适配即可。

大家可以试试白嫖 Github CI自动化构建，快还省事。
https://github.com/100askTeam/buildroot-external-mq/blob/main/.github/workflows/buildroot-external-mq.yml
自己增加一个专门的自动构建脚本，在上面的Actions里面启用自动化构建。

构建完成后，会在当前页面输出一个 sdcard.img镜像文件 可以直接下载。
感觉大大增加了开发效率，最主要是免费😀 。
