cd ~/OpenHarmony/master
repo init -u https://gitee.com/openharmony/manifest.git -b master --no-repo-verify

repo sync -c
repo forall -c 'git lfs pull'
bash ./build/prebuilts_download.sh
rm ../OpenHarmony_canary_prebuilts -rf
```

#### 1.2.2 OpenHarmony-3.2-Beta2版本下载

[版本介绍链接](https://gitee.com/openharmony/docs/blob/master/zh-cn/release-notes/OpenHarmony-v3.2-beta2.md)

```shell
mkdir -p ~/OpenHarmony/OpenHarmony-3.2-Beta2
cd ~/OpenHarmony/OpenHarmony-3.2-Beta2
repo init -u https://gitee.com/openharmony/manifest -b OpenHarmony-3.2-Beta2 --no-repo-verify
repo sync -c
repo forall -c 'git lfs pull'
repo start OpenHarmony-3.2-Beta2 --all
bash ./build/prebuilts_download.sh
rm ../OpenHarmony_canary_prebuilts -rf
```

#### 1.2.3 OpenHarmony-3.2-Beta3版本下载

[版本介绍链接](https://gitee.com/openharmony/docs/blob/master/zh-cn/release-notes/OpenHarmony-v3.2-beta3.md)

```shell
mkdir -p ~/OpenHarmony/OpenHarmony-3.2-Beta3
cd ~/OpenHarmony/OpenHarmony-3.2-Beta3
repo init -u https://gitee.com/openharmony/manifest -b OpenHarmony-3.2-Beta3 --no-repo-verify
repo sync -c
repo forall -c 'git lfs pull'
repo start OpenHarmony-3.2-Beta3 --all
bash ./build/prebuilts_download.sh
rm ../OpenHarmony_canary_prebuilts -rf
```

### 1.3 自定义分支代码下载-----C9XX

#### 1.3.1 基于OpenHarmony-3.0-LTS的thead代码下载、编译和烧录

##### 1.3.1.1 代码下载

```shell
# 拉取代码
repo init -u http://10.20.42.40/riscv_openharmoney/manifest.git -b riscv_thead -m ohos-3.0lts-c9xx.xml --no-repo-verify
repo sync -c
repo forall -c 'git lfs pull'
repo start OpenHarmony-3.0-LTS --all
bash ./build/prebuilts_download.sh
rm ../OpenHarmony_canary_prebuilts -rf
```

##### 1.3.1.2 代码编译

开发过程中建议单模块编译

```shell
# 全量代码编译
./build.sh --product-name c9xx --ccache

# 单模块编译
# module_name举例："kernel:kernel"，表示编译kernel目录下的kernel模块，所有后面的kernel是module_name
./build.sh --product-name c9xx --ccache --build-target module

# 内核模块编译
# 方法一：单模块编译
./build.sh --product-name c9xx --ccache --build-target kernel
# 方法二：手动编译
cd device/thead/c9xx/kernel
./build_kernel_single.sh
```

##### 1.3.1.3 镜像烧录

待补充

#### 1.3.2 基于OpenHarmony-3.2-Beta2的thead代码下载、编译、烧录

##### 1.3.2.1 代码下载

```shell
# 拉取代码
repo init -u https://gitee.com/ohos4riscv/manifest -b OpenHarmony-3.2-Beta2 -m thead_develop.xml --no-repo-verify
repo sync -c
repo forall -c 'git lfs pull'
repo start OpenHarmony-3.2-Beta2 --all
bash ./build/prebuilts_download.sh
rm ../OpenHarmony_2.0_canary_prebuilts -rf

# 临时方案
repo init -u https://gitee.com/ohos4riscv/manifest -b OpenHarmony-3.2-Beta2 -m thead_develop_tmp.xml --no-repo-verify
repo sync -c
repo forall -c 'git lfs pull'
repo start OpenHarmony-3.2-Beta2 --all
bash ./build/prebuilts_download.sh
rm ../OpenHarmony_2.0_canary_prebuilts -rf
```

##### 1.3.1.2 代码编译

开发过程中建议单模块编译

```shell
# 全量代码编译
./build.sh --product-name c9xx --ccache

# 内核模块编译
# 方法一：单模块编译
./build.sh --product-name c9xx --ccache --build-target kernel
# 方法二：手动编译-----当前会编译失败
cd device/thead/c9xx/kernel
./build_kernel_single.sh
```

##### 1.3.1.3 内核文件编译

- 编译内核

```shell
  ./build.sh --product-name c9xx --ccache --build-target kernel
  ```

- 进入临时内核目录中

```shell
  cd out/kernel/src_tmp/linux-5.10
  ```

- 打开并修改文件`drivers/hdf/khdf/Makefile`

```shell
  vim drivers/hdf/khdf/Makefile
  # 将26,27,28行删除，然后将HCS_DIR修改为
  HCS_DIR := ../../../$(PRODUCT_PATH)/hdf_config/khdf
  ```

- 重新编译内核

```shell
  ROOT_DIR=../../../..
  PRODUCT_COMPANY=thead
  PRODUCT_NAME=c9xx
  export PRODUCT_PATH=${ROOT_DIR}/vendor/${PRODUCT_COMPANY}/${PRODUCT_NAME}
  export DEVICE_COMPANY=thead
  export DEVICE_NAME=c9xx
  export PRODUCT_COMPANY=thead
  ./make-ohos.sh THEAD-LIGHTB enable_ramdisk
  ```

##### 1.3.1.4 ko文件编译

将[module.lds](./module.lds)拷贝到`out/kernel/OBJ/linux-5.10/scripts`目录中，然后编译ko时将内核路径直接链接`out/kernel/OBJ/linux-5.10/`路径即可
