编译环境：ubuntu 18.0.4的PC机
一、安装编译依赖库
sudo apt-get install repo git-core gitk git-gui gcc-arm-linux-gnueabihf u-boot-tools device-tree-compiler \
gcc-aarch64-linux-gnu mtools parted libudev-dev libusb-1.0-0-dev python-linaro-image-tools \
linaro-image-tools gcc-4.8-multilib-arm-linux-gnueabihf gcc-arm-linux-gnueabihf libssl-dev \
gcc-aarch64-linux-gnu g+conf autotools-dev libsigsegv2 m4 intltool libdrm-dev curl sed make \
binutils build-essential gcc g++ bash patch gzip bzip2 perl tar cpio python unzip rsync file bc wget \
libncurses5 libqt4-dev libglib2.0-dev libgtk2.0-dev libglade2-dev cvs git mercurial rsync openssh-client \
subversion asciidoc w3m dblatex graphviz python-matplotlib libc6:i386 libssl-dev texinfo \
liblz4-tool genext2fs lib32stdc++6
二、下载gcc-linaro-6.3.1-2017.05-x86_64_aarch64-linux-gnu
wget http://releases.linaro.org/components/toolchain/binaries/6.3-2017.05/aarch64-linux-gnu/gcc-linaro-6.3.1-2017.05-x86_64_aarch64-linux-gnu.tar.xz
三、下载rk339pro内核源码
git clone https://github.com/rockchip-toybrick/kernel
四、修改内核源文件
修改make.sh（注意改成gcc-linaro的路径）
#!/bin/bash

五、编译
初次编译大约5分钟左右
./make.sh linux prod
编译完成后根目录会有内核镜像：boot_linux.img
六、下载内核
使用官方工具 AndroidTool_Release_v2.64，将上一步编译好的内核下载至rk3399pro(可以只下载boot_linux.img)

7、网络参数设置
一切编译好之后，将air720D插入rk3399pro的mini pcie口并且把sim卡插入（注意别把sim卡插反了）
启动后查看设备
ls /dev/ttyUSB*
设置网络参数：
设置网卡1 内网ip /etc/network/interfaces
# interfaces(5) file used by ifup(8) and ifdown(8)
# Include files from /etc/network/interfaces.d:
source-directory /etc/network/interfaces.d
auto lo
#开机自动连接网络
auto eth0
iface lo inet loopback
allow-hotplug eth0
#static表示使用固定ip，dhcp表述使用动态ip
iface eth0 inet static
#设置ip地址
address 192.168.1.8
netmask 255.255.255.0
gateway 192.168.1.1
dns-nameservers 114.114.114.114 8.8.8.8
此时查看ifconfig ,如果没有出现 rndis_host 1-1:1.0 eth1 中的 eth1 ，则发送ifconfig -a ,此时发现有eth1 但是 没有ip 地址，发送 udhcpc -i eth1 出现地址后，即可使用此网卡进行上网
#下载
sudo apt install udhcpc
#执行
udhcpc -i eth1
出现地址后，即可使用此网卡进行上网
八、通讯air720获取iccid和imei
#可用minicom工具
sudo apt install minicom
#打开串口
sudo minicom -D /dev/ttyUSB1
