-## 1、简介 - -本节指导开发者在Hi3516DV300开发板上运行第一个应用程序，其中包括新建应用程序、编译、烧写、运行等步骤，最终输出“Hello World!” - -#### 1.1.HelloWorld 运行效果 - - ![0](./resource/0.png) - - -#### 1.2.支持OpenHarmony版本 - -OpenHarmony 3.0 LTS、OpenHarmony 3.1 Beta。 - - -#### 1.3.开发板介绍 - -Hi3516DV300是新一代行业专用Smart HD IP摄像机SOC，集成新一代ISP(Image Signal Processor)、H.265视频压缩编码器、高性能NNIE引擎，在低码率、高画质、智能处理和分析、低功耗等方面引领行业水平。 - -开发板实物图如下： - - ![1](./resource/1.jpg) - -## 2、 环境搭建 - -这里在Ubuntu 20.04版本以Docker环境为例 - -#### 2.1获取Docker环境 - -``` -#安装Docker -cd ~ -curl -fsSL https://get.docker.com -o get-docker.sh -chmod a+x get-docker.sh -sudo ./get-docker.sh - -#获取Docker镜像 -sudo docker pull swr.cn-south-1.myhuaweicloud.com/openharmony-docker/openharmony-docker-standard:0.0.5 - -#进入源码根目录执行如下命令，从而进入Docker构建环境 -sudo docker run -it -v $(pwd):/home/openharmony swr.cn-south-1.myhuaweicloud.com/openharmony-docker/openharmony-docker-standard:0.0.5 -``` - - -## 3、 获取源码 - -#### 3.1.配置git和安装repo - -参考[官网文章](https://gitee.com/openharmony/docs/blob/OpenHarmony-3.0-LTS/zh-cn/device-dev/quick-start/quickstart-standard-docker-environment.md) 步骤学习 - -``` -#安装Ubuntu 20.04 - -# 安装repo -curl

-repo init -u https://gitee.com/openharmony/manifest.git -b refs/tags/OpenHarmony-v3.1-Beta --no-repo-verify -repo sync -c -repo forall -c 'git lfs pull' -``` -#### 3.3.执行预编译脚本 - -``` -#在源码根目录下执行脚本，安装编译器及二进制工具 -#下载的prebuilts二进制默认存放在与OpenHarmony同目录下的OpenHarmony_2.0_canary_prebuilts下 -./build/prebuilts_download.sh -``` - -## 4、编写自己的hello world - -#### 4.1 新建目录及源码。 - -在源码根目录下创建hello/helloworld/src/helloworld.c目录及文件，代码如下所示，用户可以自定义修改打印内容（例如：修改World为OHOS）。其中helloworld.h包含字符串打印函数HelloPrint的声明。当前应用程序可支持标准C及C++的代码开发。 - -``` -#include -#include "helloworld.h" - -int main(int argc, char **argv) -{ - HelloPrint(); - return 0; -} - -void HelloPrint() -{ - printf("\n************************************************\n"); - printf("\n\t\tHello World!\n"); - printf("\n************************************************\n"); -} -``` - -再添加头文件hello/helloworld/include/helloworld.h，代码如下所示。 - -``` -#ifndef HELLOWORLD_H -#define HELLOWORLD_H -#ifdef __cplusplus -#endif - -void HelloPrint(); - - -#endif -#endif // HELLOWORLD_H -``` - -#### 4.2 新建编译组织文件。 - -###### 4.2.1 新建编译组织文件。新建hello/helloworld/BUILD.gn文件，内容如下所示： -``` -import("//build/ohos.gni") -ohos_executable("helloworld") { - sources = [ - "src/helloworld.c" - ] - include_dirs = [ - "include" - ] - part_name = "hello_exe" - install_enable = true -} - - -``` - -###### 4.2.2 新建hello/ohos.build文件，添加hello部件描述，内容如下所示。 - -``` -{ - "subsystem": "hello", - "parts": { - "hello_exe": { - "module_list": [ - "//hello/helloworld:helloworld" - ] - } - } -} - - -``` - - -#### 4.3 修改产品配置文件。 - -在productdefine\common\products\rk3568.json中添加对应的hello部件，直接添加到原有部件后即可。 - -``` - "usb:usb_manager_native":{}, - "applications:prebuilt_hap":{}, - "wpa_supplicant-2.9:wpa_supplicant-2.9":{}, - "hello:hello_exe":{} -``` - -## 5、 源码编译 - -``` -#进入源码根目录，执行如下命令进行版本编译 -./build.sh --product-name Hi3516DV300 --ccache - -#编译完成后会有如下显示 -=====build Hi3516DV300 successful. - -``` - -生成固件路径 out/hi3516dv300/packages/phone/images - - -## 6、镜像烧录 -USB烧录 - -#### 6.1、请连接好电脑和待烧录开发板，需要同时连接串口和USB口，具体可参考[Hi3516DV300开发板介绍](https://gitee.com/openharmony/docs/blob/OpenHarmony_1.0.1_release/zh-cn/device-dev/quick-start/Hi3516%E5%BC%80%E5%8F%91%E6%9D%BF%E4%BB%8B%E7%BB%8D.md) - - - ![3](./resource/3.png) - - -#### 6.2、打开电脑的设备管理器，查看并记录对应的串口号。 -如果对应的串口异常，请根据[Hi3516DV300/Hi3518EV300开发板串口驱动安装指导](https://device.harmonyos.com/cn/docs/documentation/guide/hi3516_hi3518-drivers-0000001050743695) 安装USB转串口的驱动程序。 - - ![4](./resource/4.png) - -#### 6.3、安装USB驱动 - -下载USB驱动，[下载地址](http://www.hihope.org/download/download.aspx?mtt=11) - - - ![2](./resource/2.png) - -如果安装驱动后，还提示不识别的USB设备，请将下面的内容保存未一个注册表文件，如test.reg，然后注册。 - - -Windows Registry Editor Version 5.00 - -``` -[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\usbflags\12D1D0010100] -"SkipBOSDescriptorQuery"=hex:01,00,00,00 -"osvc"=hex:00,00 -"IgnoreHWSerNum"=hex:01 -``` - -#### 6.4、使用Hitools，烧写，然后按住串口边上的复位键，插拔USB电源线重启 - - ![5](./resource/5.jpg) - - -#### 6.5、烧写成功 - - ![6](./resource/6.png) - - -## 7、镜像运行 - - -#### 7.1 相关配置 -第一次烧录3.1镜像后，启动时需要设置，参考官网中给的命令设置（仅第一次烧录时需要）。使用方式：在终端1窗口设置正确端口号，如COM3，点击连接。重启开发板电源时，迅速按回车，输入如下命令 - -重启电源后，及时按回车 进入命令模式 - ![24](./resource/24.jpg) - -``` -setenv bootargs 'mem=640M console=ttyAMA0,115200 mmz=anonymous,0,0xA8000000,384M clk_ignore_unused rootdelay=10 hardware=Hi3516DV300 init=/init root=/dev/ram0 rw blkdevparts=mmcblk0:1M(boot),15M(kernel),20M(updater),2M(misc),3307M(system),256M(vendor),-(userdata)'; - -setenv bootcmd 'mmc read 0x0 0x82000000 0x800 0x4800; bootm 0x82000000' - -save - -reset - -``` - -#### 7.2 运行helloworld - -打开串口后，在任意目录（以设备根目录为例）下输入命令helloworld后回车，即出现“Hello World!”字样。 - - ![0](./resource/0.png) diff --git a/docs/hi3516_dv300_helloworld/resource/0.png
