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、加快git获取速度配置
# 在https://www.ipaddress.com/查询以下域名的IP地址：
github.global.ssl.fastly.net
github.com
# 编辑
sudo vim /etc/hosts
# 添加下面两行（IP替换为上面查询出来的IP）
140.82.114.4 github.com
199.232.69.194 github.global.ssl.fastly.net
# 保存更新DNS
sudo /etc/init.d/networking restart
二、源码获取与编译
# 完整拉取linux极大，建议只拉取单层分支，减少等待时间：
git clone --depth=1 -b f1c100s-480272lcd-test https://github.com/Icenowy/linux.git
# 进入linux源码目录
cd linux/
#获取配置好的配置文件到linux源码的根目录（如果已存在.config，则需要替换）
wget http://dl.sipeed.com/LICHEE/Nano/SDK/config
cp config .config
#图形配置与编译
make ARCH=arm menuconfig
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- -j12
生成的 zImage 在 arch ‣ arm ‣ boot 目录下；将其放入第一分区。
生成的设备树suniv-f1c100s-licheepi-nano.dtb在linux ‣ arch ‣ arm ‣ boot ‣ dts目录下；将其放入第一分区。
三、修改顶层Makefile
在内核根目录下的Makefile修改默认编译器，可以直接用make编译：
# ARCH ?= $(SUBARCH)
# CROSS_COMPILE ?= $(CONFIG_CROSS_COMPILE:"%"=%)
ARCH ?= arm
CROSS_COMPILE ?= arm-linux-gnueabi-
四、烧录
# 查看芯片信息，确认是否成功进入fel模式：
sudo sunxi-fel ver
# 烧录到RAM试运行
sudo sunxi-fel -p uboot u-boot-sunxi-with-spl.bin write 0x80000000 zImage write 0x80700000 suniv-f1c100s-licheepi-nano.dtb
