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

VERSION="2.0"

JOB=`sed -n "N;/processor/p" /proc/cpuinfo|wc -l`

DTB=toybrick-$2

{ USB_DEVICE(OPTION_VENDOR_ID, OPTION_PRODUCT_RICOLA_QUAD_LIGHT) },

{ USB_DEVICE(OPTION_VENDOR_ID, OPTION_PRODUCT_RICOLA_NDIS) },

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
