开发环境 

 

 

推荐采用Windows+Ubuntu环境进行开发：

 

- Windows环境用于编写代码、下载程序和烧入固件等，系统要求：Windows 10 64位系统。

 

- Linux环境用于代码下载、编译工程和生成固件等，系统要求：Ubuntu 20.04 64位及以上版本。

 

注意：若不确定所使用的Linux设备的系统及版本，请在bash中运行如下命令查看：

lsb_release -a

请在确认Linux系统不低于Ubuntu 20.04.XX LTS的情况下执行后续的步骤；否则，请升级或更换合适的Liunx设备。
 

 

若需要支持在Linux与Windows之间的文件共享以及编辑，请在Linux设备上适当地安装和配置samba、vim等常用软件。

 

OpenHarmony开发环境搭建：

 

[准备开发环境]

[安装库和工具集]

https://gitee.com/openharmony/docs/blob/master/zh-cn/device-dev/quick-start/quickstart-pkg-install-package.md

 

 

编译工具安装 

 

 

[gcc工具下载]

https://repo.huaweicloud.com/harmonyos/compiler/gcc_riscv32/7.3.0/linux/gcc_riscv32-linux-7.3.0.tar.gz

 

设置环境变量

 

说明：如果直接采用编译好的riscv32 gcc包，请先执行以下命令将压缩包解压到用户的home(也可以是其他目录，注意使用实际的PATH即可)：

tar -xvf gcc_riscv32-linux-7.3.0.tar.gz -C ~

 

将以下命令拷贝到`.bashrc`文件的最后一行，保存并退出。

export PATH=~/gcc_riscv32/bin:$PATH

 

执行下面命令使环境变量生效:

source ~/.bashrc

 

Shell命令行中输入如下命令 `riscv32-unknown-elf-gcc -v`，如果能正确显示编译器版本号，表明编译器安装成功。

[安装hb工具]

https://gitee.com/openharmony/docs/blob/master/zh-cn/device-dev/quick-start/quickstart-pkg-install-tool.md

注意：默认下载的是master分支版本，如果想下载其他分支版本请将-b master改为需要下载的分支。

 

比如下载OpenHarmony-4.0-Release:

repo init -u [e-mail]:openharmony/manifest.git -b OpenHarmony-4.0-Release --no-repo-verify

 

hb 安装报错：

WARNING: The scripts alldefconfig, allmodconfig, allnoconfig, allyesconfig, defconfig, genconfig, guiconfig, listnewconfig, menuconfig, oldconfig, olddefconfig, savedefconfig and setconfig are installed in '/home/xxx/.local/bin' which is not on PATH.
Consider adding this directory to PATH or, if you prefer to suppress this warning, use --no-warn-script-location.
WARNING: The script hb is installed in '/home/xxx/.local/bin' which is not on PATH.
Consider adding this directory to PATH or, if you prefer to suppress this warning, use --no-warn-script-location.```

 

解决办法：

1. 将以下命令拷贝到.bashrc文件的最后一行，保存并退出。
 

export PATH=~/.local/bin:$PATH

 

2. 执行如下命令更新环境变量

source ~/.bashrc
python3 -m pip uninstall ohos-build 
python3 -m pip install --user build/hb

 

工程编译 

 

 

选择目标工程：

执行hb set选择hpmicro下的hpm6750evk2:

 

也可以直接通过命令指定
 

hb set -p hpm6750evk2

 

编译工程

执行`hb build -f` 进行工程编译，编译成功后显示如下内容：

 

打开xts功能

执行hb build -f --gn-args="build_xts=true"命令进行xts编译。
 

 

镜像烧录 

 

 

下载安装烧录工具(windows)

点击[先楫系列资料] 百度网盘下载sdk/HPMicro_Manufacturing_Tool_vx.x.x.zip

网盘链接：https://pan.baidu.com/s/1RaYHOD7xk7fnotmgLpoAlA?pwd=xk2n

 

下载后解压HPMicro_Manufacturing_Tool_vx.x.x.zip文件到任意目录。

找到 hpm_manufacturing_gui.exe，双击执行程序：

 

下载程序到开发板：

1. 将开发板的 USB2UART0 接口连接至PC，正确连接后，PC可识别到一路usb串口，hpm6750evk2板载了ch340 usb转串口芯片。

 

2. 将BOOT拨码开关设置为:

boot0: 0 
boot1: 1

 

拨码开关设置好后，点击开发板的`RESTN`按钮，进行复位，复位后进入到isp模式。

 

3. 配置hpm_manufacturing_gui的 类型为：UART 并选择选择步骤1中对用的串口，点击 连接：

 

连接成功：

 

4. 拷贝编译好的固件程序out/hpm6750evk2/hpm6750evk2/OHOS_Image.bin到windows。

 

5. 选择固件程序，点击 烧写 进行下载:

 

6. 设置拨码开关为正常模式

boot0: 0 
boot1: 0

7. 打开一个串口终端 MobaXterm，重启开发板，串口打印启动信息

 

8. hpm_manufacturing_gui更多用法，请参考：HPMicro_Manufacturing_Tool_vx.x.x\doc\user_manual.html

 

openocd 进行调试镜像  

 

 

1. 下载openocd

git clone [e-mail]:hpmicro/riscv-openocd.git -b riscv-hpmicro

2. 安装依赖工具

sudo apt install libtool libusb-1.0-0-dev libhidapi-dev libftdi-dev

3. 安装

进入源码目录，并执行下面的命令

./bootstrap
./configure
make -j16
sudo make install
sudo cp contrib/60-openocd.rules /etc/udev/rules.d/

4. 连接烧写和目标板

5. 启动openocd

进入到ohos源码device/soc/hpmicro/sdk/hpm_sdk/boards/openocd,执行如下命令：
