# hi3798cv200 android compile * [sdk 百度云下载 密码:w11f](https://pan.baidu.com/s/1kcMvlGeNHi-aMNGyZPTVqA ) * 开发环境搭建和初次编译参考`Android 解决方案 开发指南.pdf`- >`开发环境配置` * 烧写工具`HiTool-STB-3.1.35.zip` 会在成功编译镜像后自动拷贝到out文件夹。 ```bash $ sudo find / -name HiTool-STB* /home/jay/hi3798cv200/HiSTBAndroidV600R002C00SPC030/out/target/product/Hi3798CV200/HiTool-STB-3.1.35.zip ``` > **提示**：部分windows应用工具直接打包到了sdk，压缩成tar包。所以对于部分工具需要尝试在解压后linuxsdk 目录搜索。 ## sdk 目录结构 ```bash $tree ├── abi ├── art ├── bionic ├── bootable ├── build ├── cts ├── dalvik ├── developers ├── development ├── device ├── docs ├── external ├── frameworks ├── hardware ├── install_notes_cn.txt #开发文档 ├── install_notes_en.txt ├── libcore ├── libnativehelper ├── Makefile ├── ndk ├── out ├── packages ├── pdk ├── prebuilts #部分依赖的工具，需要提前编译 ├── sdk ├── system └── toolss ``` ## 初始化编译环境 参考`ServerInstall.sh`进行初始化环境，主要是包含java 、python、依赖库、gcc安装，然而很多依赖版本过低，所以必须要添加 ubuntu12.04或者14.04源安装。 当前 ubuntu 源已经放弃部分老版本的更新维护，所以没有办法直接降级到文章中的 bardy 08.04 源直接安装，对于java7的安装需要更改source源到到当前维护的最低版本precise、trusty等，即： ```c The following releases are also available which have been superseded by later point releases (the current point release is available on releases.ubuntu.com as usual): Ubuntu 12.04.4 LTS (Precise Pangolin) Ubuntu 14.04.4 LTS (Trusty Tahr) Ubuntu 16.04.4 LTS (Xenial Xerus) Ubuntu 18.04 LTS (Bionic Beaver) ``` > **参考**:[Old Ubuntu Releases](http://old-releases.ubuntu.com/releases/) ### java ```bash $sudo apt-get install openjdk-7-jre ``` > **警告**：不要尝试使用java8 否则后面会直接提示错误，参考[Troubleshotings/required java version is: "1.7.x"](#Troubleshotings/required java version is: "1.7.x") 设置环境变量 ```bash #~/.bashrc export JAVA_HOME="/usr/lib/jvm/java-7-openjdk-amd64" export PATH="/usr/lib/jvm/java-7-openjdk-amd64/bin":$PATH ``` ### gcc 交叉编译环境通过`arm-hisiv200-linux.tar.bz2`安装，解压后参考内根目录的安装脚本，主要包含建立软连接和配置环境变量。 ```bash #cross.install TOP_DIR=/home/jay/hi3798cv200/env_init TOOL_DIR=$TOP_DIR/arm-hisiv200-linux TAR_BIN_DIR=$TOOL_DIR/target/bin BIN_FILES=$TOOL_DIR/bin/arm-hisiv200-linux-gnueabi-* LN_FILE_NAME=arm-hisiv200-linux- TOOLS_PKG="`dirname $0`/arm-hisiv200-linux.tar.bz2" mkdir -p $TAR_BIN_DIR for armlinux in $BIN_FILES do echo "ln $armlinux $TAR_BIN_DIR/$LN_FILE_NAME`basename $armlinux | cut -b 28-` -sv" ln $armlinux $TAR_BIN_DIR/$LN_FILE_NAME`basename $armlinux | cut -b 28-` -sv done ``` 配置环境变量 ```bash export PATH=/home/jay/hi3798cv200/env_init/arm-hisiv200-linux/target/bin":$PATH ``` ## 烧写固件 * `HiBurn 工具使用指南.pdf` ### sch uboot 烧写原理：HiBurn工具在开始烧写后，首选与bootrom 进行交互，工具DDR参数传送到传到bootrom，为uboot 下载阶段 5%处，然后初始化 DDR，再把uboot 传 输到DDR中，uboot 下载阶段 100%处表示传输完毕，再从 DDR启动uboot，uboot 启 动完成后，工具开始与uboot 进行交互，发送烧写命令，将 DDR中的uboot 烧 到 Flash对应地址中。 其他镜像分区烧写原理：其他镜像分区，如kernel ，rootfs 等分区，工具默认采用网口 传输的方式，客户可选 烧和非裸烧两种方式进行烧写，裸烧即为在按分区烧写或 按Emmc 烧写中勾选uboot 进行烧写，此时 uboot 会被烧写到Flash中，非裸烧即为不 勾选uboot，仅勾选其他分区进行烧写，此时需要保证当前单板上已经存在 uboot，烧 写时工具会启动uboot，与其交互，通过向 uboot 发送TFTP命令与Write命令，完成 烧写。 ### do 常规操作，通过串口烧写fastboot，通过tftp烧写其他分区镜像。对于目标烧写设备的静态ip地址信息需要手动指定后通过串口烧写。  成功烧写fastboot过后可以通过串口连接打印环境变量printenv确定静态ip已经正确配置，通过ping 确定已经在同一网络。 ## Troubleshootings ### apt update failed ```bash jay@mxj-build:~/hi3798cv200/env_init$ sudo ./ServerInstall.sh E: Unable to locate package mingw32 E: Package 'uboot-mkimage' has no installation candidate E: Package 'ia32-libs' has no installation candidate E: Package 'gcc-4.4' has no installation candidate E: Package 'g++-4.4' has no installation candidate E: Unable to locate package g++-4.4-multilib E: Couldn't find any package by glob 'g++-4.4-multilib' E: Couldn't find any package by regex 'g++-4.4-multilib' E: Unable to locate package gcc-4.4-multilib E: Couldn't find any package by glob 'gcc-4.4-multilib' E: Couldn't find any package by regex 'gcc-4.4-multilib' Please re-login system to make new settings take effect ``` 直接通过apt-get 安装如下依赖库和软件包提示找不到源，尝试添加老版本发布源，也不能正常下载，剔除不能正常安装的源，其他的参考[初始化编译环境/gcc](#初始化编译环境/gcc) 安装。 ```bash $sudo apt-get install git gnupg flex bison gperf build-essential zip curl libc6-dev libncurses5-dev x11proto-core-dev libx11-dev libreadline6-dev libgl1-mesa-glx libgl1-mesa-dev g++-multilib mingw32 tofrodos python-markdown libxml2-utils xsltproc zlib1g-dev xsltproc gettext lib32ncurses5-dev libtool autoconf $sudo apt-get install uboot-mkimage ia32-libs gcc-4.4 g++-4.4 g++-4.4-multilib gcc-4.4-multilib ``` ```bash $sudo apt-get install u-boot-tools ``` ### gcc not found 参考[初始化编译环境/gcc](#初始化编译环境/gcc) 安装并且确定已经正确配置环境变量。 ### required java version is: "1.7.x" ```bash Your version is: openjdk version "1.8.0_191" OpenJDK Runtime Environment (build 1.8.0_191-8u191-b12-0ubuntu0.16.04.1-b12) OpenJDK 64-Bit Server VM (build 25.191-b12, mixed mode).
