介绍

这款微型开发板专为运行 Linux 而设计。尽管机身很小，但它具有所有重要功能。板载F1C200S作为主控芯片，提供多种常用外设端口：GPIO、I2C&SPI、SDIO、Audio port(record,play), Video(RGB565 Display, touch, DVP), USB Host, OTG等. 此外，板卡内置64MB DDR和板载128MB Nand Flash，全面支持Linux生态，运行完整的Python。

目前该产品是完全开源的，用户可以根据自己的需求编译任意模块。但是，它主要面向 Python 开发人员和高级爱好者，因为它上手有点困难。

芯片优缺点

缺点：主频过低，内核太古老（ARM9）
优点：便宜，内置DDR，资料丰富（老芯片的优势）

MangoPi的Buildroot一键编译

地址：https://github.com/mangopi-sbc/buildroot-mangopi-r

安装软件包

sudo apt install rsync wget unzip build-essential git bc swig libncurses-dev libpython3-dev libssl-dev
sudo apt install python3-distutils

下载BSP包

git clone https://github.com/mangopi-sbc/buildroot-mangopi-r

第一次编译

注意：构建固件不需要 Root 权限。

应用默认配置

注意：应用 defconfig 会将所有 buildroot 配置重置为默认值。

通常，您只需要应用一次。

cd buildroot-mangopi-r
make widora_mangopi_r3_defconfig

常规编译

make -j16

如果更改了 DTS 或 kenrel 构建

./rebuild-kernel.sh

如果更改了 Uboot，则构建

./rebuild-uboot.sh

加快构建进度

在百度云下载离线的 dl
Buildroot 将在编译固件时下载源代码。您可以获取“dl”文件夹的可信存档以加快速度。 https://pan.baidu.com/s/1-5CiMwXMQWjZxsFhsyRC5Q?pwd=1111

.make source

没有搞清楚这里是怎么用的，现在是下载了两个包：

buildroot-dl-20220130.zip
buildroot-mangopi-r-master.zip
是不是把buildroot-dl-20220130.zip解压到buildroot-mangopi-r-master目录里面呢？

最终编译完成了。
