• sdk 百度云下载 密码:w11f

• 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。

  $ 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。

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：

The following releases are also available which have been superseded by later point releases (the current point release is available on releases.ubuntu.com as usual):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

java

$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

#~/.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。

#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

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。

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 安装。

参考初始化编译环境/gcc 安装并且确定已经正确配置环境变量。

checkpolicy用于检测SELinux策略（SELinux policy）的工具，源码位于sdk external/checkpolicy/,里面*.l和.y源文件需要通过flex和bision解释器翻译为*.c源码再通过gcc编译。

对于sdk的已经原装了bison和flex。这里之所以报错是因为版本flex版本过低。

./prebuilts/misc/linux-x86/

├── bison

这里直接安装 flex和bison,然后软链接到sdk目录。

$sudo apt-get install flex bison

./out/target/product/Hi3798CV200/obj/TOOLS_OBJ/mtd-utils/tmp/mtd-utils-1.5.0

如上目录保存了mtd-utils-1.5.0.tar.bz2 会在编译过程解压编译，直接在ubuntu16.04 上面编译会因为兼容导致报错,软件包通过如下Makefile 配置。所以这里可以修改配置和替换包的方式直接更新为mtd-utils-2.0.0

$ rgrep  "mtd-utils-1.5.0" -n --color -I -C2 ./
./device/hisilicon/bigfish/sdk/tools/linux/utils/mtd-utils/Makefile-14-STRIP          := strip
./device/hisilicon/bigfish/sdk/tools/linux/utils/mtd-utils/Makefile:16:MTD_UTILS      := mtd-utils-1.5.0

需要注意的是，默认mtd-utils-2.0.0通过cmake编译，需要cmake configure，这里直接选择修改/usr/include/netdb.h在includde头文件之后定义宏，使其失效。

$vi /usr/include/netdb.h

#define __USE_XOPEN2K  0

注意：定义__USE_XOPEN2K 值为0是使其之后所有的条件编译失效，所以要尽量选择在#include头文件之后，变值被覆盖。
