先楫半導體攜手OpenHarmony正式發布HPMicro ohos v1.0.0

[獲取源碼]

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

[安裝hb工具]

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

注意：默認下載的是master分支版本，如果想下載其他分支版本請將-b master改為需要下載的分支。

比如下載OpenHarmony-4.0-Release:

repo init -u git@gitee.com:openharmony/manifest.git -b OpenHarmony-4.0-Release --no-repo-verify

hb 安裝報錯：

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.```

解決辦法：

1. 將以下命令拷貝到.bashrc文件的最后一行，保存并退出。

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

2. 執行如下命令更新環境變量

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

工程編譯

選擇目標工程：

執行hb set選擇hpmicro下的hpm6750evk2:

也可以直接通過命令指定

hb set -p hpm6750evk2

編譯工程

執行`hb build -f` 進行工程編譯，編譯成功后顯示如下內容：

打開xts功能

執行hb build -f --gn-args="build_xts=true"命令進行xts編譯。

鏡像燒錄

下載安裝燒錄工具(windows)

點擊[先楫系列資料] 百度網盤下載sdk/HPMicro_Manufacturing_Tool_vx.x.x.zip

網盤鏈接：https://pan.baidu.com/s/1RaYHOD7xk7fnotmgLpoAlA?pwd=xk2n

下載后解壓HPMicro_Manufacturing_Tool_vx.x.x.zip文件到任意目錄。

找到 hpm_manufacturing_gui.exe，雙擊執行程序：

下載程序到開發板：

1. 將開發板的USB2UART0接口連接至PC，正確連接后，PC可識別到一路usb串口，hpm6750evk2板載了ch340 usb轉串口芯片。

2. 將BOOT撥碼開關設置為:

boot0: 0 
boot1: 1

撥碼開關設置好后，點擊開發板的`RESTN`按鈕，進行復位，復位后進入到isp模式。

3. 配置hpm_manufacturing_gui的 類型為：UART 并選擇選擇步驟1中對用的串口，點擊連接：

連接成功：

4. 拷貝編譯好的固件程序out/hpm6750evk2/hpm6750evk2/OHOS_Image.bin到windows。

5. 選擇固件程序，點擊燒寫進行下載:

6. 設置撥碼開關為正常模式

boot0: 0 
boot1: 0

7. 打開一個串口終端MobaXterm，重啟開發板，串口打印啟動信息

8. hpm_manufacturing_gui更多用法，請參考：HPMicro_Manufacturing_Tool_vx.x.xdocuser_manual.html

openocd 進行調試鏡像

1. 下載openocd

git clone git@gitee.com:hpmicro/riscv-openocd.git -b riscv-hpmicro

2. 安裝依賴工具

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

3. 安裝

進入源碼目錄，并執行下面的命令

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

4. 連接燒寫和目標板

5. 啟動openocd

進入到ohos源碼device/soc/hpmicro/sdk/hpm_sdk/boards/openocd,執行如下命令：

$ openocd -s . -f probes/cmsis_dap.cfg -f soc/hpm6750-single-core.cfg -f boards/hpm6750evk2.cfg
