一、环境系统选择：

开发环境建议选用ubuntu，下面ubuntu18.04 为例

二、环境依赖安装：

1、安装依赖库

sudo apt-get install -y git-core gnupg flex bison gperf build-essential zip curl zlib1g-dev gcc-multilib g+±multilib libc6-dev-i386 lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z-dev ccache libgl1-mesa-dev libxml2-utils xsltproc unzip elfutils-libelf-devel libelf-dev gawk fontconfig

2、安装JDK

sudo apt-get install openjdk-11-jdk

安装完成后，检查是否安装成功：

javac -versionjavac 11.0.17 # 按实际安装的来看

三、软件配置：

1、git 配置

git config --global user.name 'xxx’
git config --global user.email ‘xxx@xxx.com’

2、repo配置

1.上传公钥
2.安装repo引导脚本
3.下载代码
下载服务器统一为：sdk.allwinnertech.com
下载请注意：如有lichee和android两仓库，务必放在同一级目录

四、编译软件：

T527下载后如下

1、先编译longon

./longan/build.sh config
========ACTION List: mk_config ;========
options :
All available platform:0. android1. linux
Choice [android]: 0
All available ic:0. a5271. t527
Choice [t527]: 1
All available board:0. demo1. demo_battery2. demo_car3. demo_fastboot4. pre_auto
Choice [pre_auto]: 4
All available flash:0. default1. nor
Choice [default]: 0./build.sh

2、再编译android

以pre_auto为例

$ source build/envsetup.sh
$ lunchYou're building on LinuxLunch menu .. Here are the common combinations:1. a523_af86310vat_arm64-user...118. t527_demo_car_arm64-user119. t527_demo_car_arm64-userdebug120. t527_pre_auto_arm64-user121. t527_pre_auto_arm64-userdebug...Which would you like? [aosp_arm-eng]
Pick from common choices above (e.g. 13) or specify your own (e.g. aosp_barbet-eng): 121$ make -j16
$ pack
