源码和工具打包：[CSND下载]荔枝派nano汇总资料（uboot、主线Linux、buildroot及dl包、编译烧录工具、配置及烧录文件）
一、下载源码
# 首先安装一些依赖，比如linux头文件：
sudo apt-get install linux-headers-$(uname -r)
# 下载解压
wget https://buildroot.org/downloads/buildroot-2017.08.tar.gz
tar xvf buildroot-2017.08.tar.gz
二、图形配置
cd buildroot-2017.08/
# 下载默认配置文件 buildroot.config
wget https://fdvad021asfd8q.oss-cn-hangzhou.aliyuncs.com/migrate/buildroot.config
# 复制一个并重命名
cp buildroot.config .config
# 图形界面配置
make menuconfig
配置界面：
Target options --->
Target Architecture Variant (arm926t) ---> # arm926ejs架构
[ ] Enable VFP extension support # Nano 没有 VFP单元，勾选会导致某些应用无法运行
Target ABI (EABI) --->
Floating point strategy (Soft float) ---> // 软浮点
System configuration --->
(Lichee Pi) System hostname // hostname
(licheepi) Root password // 默认账户为root 密码为licheepi
[*] remount root filesystem read-write during boot // 启动时重新挂在文件系统使其可读写
三、软件包
- 编译时会下载很多软件包，速度很慢，可以先下载下来：【dl包】百度网盘下载
- 解压出
dl文件夹放在buildroot-2017.08根目录下 - 在编译的时候发现在下载
arm-2014.05-29-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2，所以这个也要放入dl文件夹里（编译时会自动解压）。 - 这些资料在文章第一行链接里面全部打包了。
四、编译
# buildroot不能进行多线程编译
make
第一次编译失败，不清楚是否虚拟机崩溃引起的，make clean再次make就编译成功了。
编译完成的镜像包在 buildroot-2017.08 ‣ output ‣images ‣ rootfs.tar(大小98.1MB)
五、烧录
参考：全志F1C100S/F1C200S学习笔记（2）——TF/SD卡分区及系统构建烧录
使用TF卡烧录。
六、启动LOG
