【RK3399开发环境搭建】

4.1 JDK 安装

Android7.1 系统编译依赖于 JAVA 8。编译之前需安装 OpenJDK。

安装命令如下。

sudo apt-get install openjdk-8-jdk

配置 JAVA 环境变量，例如，安装路径为/usr/lib/jvm/java-8-openjdk-amd64，可在终

端执行如下命令配置环境变量。

export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64

export PATH=$JAVA_HOME/bin:$PATH

export CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/lib/tools.jar

4.2 Linux 服务器开发环境搭建

Rockchip Buildroot Linux SDK 是在 Ubuntu 16.04 上开发测试的。因此，我们推荐使用

Ubuntu 16.04 的系统进行编译。其他版本没有具体测试，可能需要对软件包做相应调整。

除了系统要求外，还有其他软硬方面的要求。

l 硬件要求：64 位系统，硬盘空间大于 40G。如果您进行多个构建，将需要更大的硬盘空间。

l 软件包依赖：除了 python 2.7，make 3.8，git 1.7 之外，还需要安装一些额外的软件

包，将在软件包安装章节中列出。

4.2.1 发布包使用 Linux 服务器系统版本

本 SDK 开发环境安装如下版本 Linux 系统，SDK 默认均以此 Linux 系统进行编译：Rockchip Buildroot Linux 软件开发指南 4 开发环境搭建

Copyright 2019 @Fuzhou Rockchip Electronics Co., Ltd. 4-2

Ubuntu 16.04.2 LTS

Linux version 4.4.0-62-generic (buildd@lcy01-30) (gcc version 5.4.0 20160609

(Ubuntu 5.4.0-6ubuntu1~16.04.4) ) #83-Ubuntu SMP Wed Jan 18 14:10:15 UTC 2017

4.2.2 网络环境搭建

请用户自行配置网络，并安装 nfs，samba，ssh 等网络组件。

4.2.3 软件包安装

操作系统安装好后，且用户已自行配置好网络环境，则可继续如下步骤完成相关软件包的安装。

1. apt-get update

$ sudo apt-get update

2. 安装 Kernel 及 U-Boot 编译需要依赖的软件包

sudo apt-get install 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 lib32z1-dev ccache libgl1-mesa-dev libxml2-utils

xsltproc unzip device-tree-compiler liblz4-tool

3. 安装 Buildroot 编译需要依赖的软件包

sudo apt-get install libfile-which-perl sed make binutils gcc g++ bash patch gzip

bzip2 perl tar cpio python unzip rsync file bc libmpc3 git repo texinfo pkg-config cmake

tree texinfo

若编译遇到报错，可以视报错信息，安装对应的软件包。

4.2.4 交叉编译工具链介绍

鉴于 Rockchip Buildroot SDK 目前只在 Linux 下编译，我们也仅提供了 Linux 下的交叉编译

工具链。其中 U-Boot 及 Kernel 使用的编译工具链预置目录在 prebuilt/gcc 下，buildroot 使用

该开源软件中编译出来的工具链。

U-Boot 及 Kernel 编译工具链

prebuilts/gcc/linux-x86/aarch64/gcc-linaro-6.3.1-2017.05-x86_64_aarch64-linux

-gnu/bin/aarch64-linux-gnu对应版本

gcc version 6.3.1 20170404 (Linaro GCC 6.3-2017.05)

Buildroot 编译工具链

buildroot/output/rockchip_rk3308_release/host/bin/aarch64-rockchip-linux-gnu对应版本

gcc version 6.4.0 (Buildroot 2018.02-rc3-00017-g9c68ede

如果需要其他平台或版本的工具链，需自行编译。

上述环境准备好后，Linux 服务器开发环境搭建已完成，可以下载编译源代码了。

4.3 编译模式

SDK 默认以 userdebug 模式编译。

使用 adb 时，需要先执行 adb root ，adb disable-verity 关闭 system 分区的 verity

特性，重启后再执行 adb root, adb remount，进而进行 push 操作来 debug。

【代码编译】

4.4.1挖掘机编译

uboot 编译步骤:

# cd u-boot

# make rk3399_defconfig

# make ARCHV=aarch64

kernel 编译步骤:

# cd kernel

# make ARCH=arm64 rockchip_defconfig -j8

# make ARCH=arm64 rk3399-sapphire-excavator-edp.img -j12

android 编译步骤:

# source build/envsetup.sh

# lunch rk3399_xxx-userdebug

# make -j20 

# ./mkimage.sh

完成编译后，执行 SDK 根目录下的 mkimage.sh 后在 rockdev/Image-xxx/目录生成完整

的固件包(xxx 是具体 lunch 的产品名)。

android 升级包:

# make otapackage -j20

# ./mkimage.sh ota -j20

#rm -rf out/target/product/rk3399_xxx/system/priv-app/*

#rm -rf out/target/product/rk3399_xxx/system/app/*

./build-rk3399-xxx.sh -o -u -v 0.0.0.4
