【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
一键编译命令：
一键编译前删除多余app：
#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
编译输出路径：T:\xxx\android7\IMAGE\RK3399-SAPPHIRE-EXCAVATOR-EDP_7.1.2_20211008.1630_1.0.0.1\IMAGES

# DH keySize < 1024, EC keySize < 224, 3DES_EDE_CBC, anon, NULL, \
# include jdk.disabled.namedCurves
# Legacy algorithms for Secure Socket Layer/Transport Layer Security (SSL/TLS)
- Remove TLSv1, TLSv1.1 from jdk.tls.disabledAlgorithms in /etc/java-8-openjdk/security/java.security file
- Restart the jack server: cd /prebuilts/sdk/tools/ ./jack-admin kill-server ./jack-admin start-server
#cd /prebuilts/sdk/tools/
