openharmony标准系统移植之添加产品编译

首先我这里下载的是源码文件包的形式，如下图，我们使用 命令 tar xvf code-v3.1-Release.tar.gz进行解压文件。解压完成后如下图，多了code-v3.1-Release文件夹，

然后需要构建我们自己的git配置，首先删除.repo/文件夹，然后修改drivers/adapter/.gitignore，这里把linux全屏蔽了，不然后期修改了文件，无法找到对应的改动。
首先安装下ruby工具，执行如下命令即可 sudo apt-get install ruby，不装可能会报错

FAILED: gen/isa/isa.yaml
[OHOS ERROR] /usr/bin/env ../../ark/runtime_core/isa/combine.rb -d ../../ark/runtime_core/isa/isa.yaml,../../ark/js_runtime/ecmascript/ecma_isa.yaml -o gen/isa/isa.yaml
[OHOS ERROR] /usr/bin/env: ‘ruby’: No such file or directory

具体报错信息如下。

=====build  error=====

然后先编译下官方已经有的产品，确保环境没有问题。 可以使用sudo apt-get install ccache命令安装 ccache，这样编译会快一点。执行如下命令即可 ./build.sh --product-name Hi3516DV300，等待编译完成，我这边等待了有几十来分钟才编译好吧，编译结果如下，说明我们的环境已经没有问题了，可以开始进行我们的移植 工作了。

首先在源码目录productdefine/common/products下，增加我们产品定义的json文件，我这里直接复制使用Hi3516DV300.json作为我们的模板修改下使用。使用命令cp Hi3516DV300.json zxyNandst.json即可得到我们的产品定义，打开文件，修改如下

{
   
   
  "product_name": "Hi3516DV300", //这里修改为我们对应的文件名, zxyNandst
  "product_company": "hisilicon", //修改为对应的产品,xingyunnand
  "product_device": "hi3516dv300", // 使用 xingyunelec
  "version": "2.0",
  "type": "standard",
  "product_build_path": "device/board/hisilicon/hispark_taurus/linux", //这里使用device/xingyunelec/xingyunnand/sdk_linux

所以修改后我们的这部分内容如下

{
   
   
  "product_name": "zxyNandst",
  "product_company": "xingyunelec",
  "product_device": "xingyunnand",
  "version": "2.0",
  "type": "standard",
  "product_build_path": "device/xingyunelec/xingyunnand/sdk_linux",
  "parts":{
   
   

然后把图片中这行删除，这个是与海思相关的文件，我们不需要，所以删除即可。

然后我们使用如下命令尝试编译下 ./build.sh --product-name zxyNandst –ccache，很明显报错

++++++++++++++++++++++++++++++++++++++++

--product-name zxyNandst –ccache
[OHOS ERROR] /home/d1/openHarmony/source/code-v3.1-Release/OpenHarmony/productdefine/common/device/xingyunnand.json not found
=====build  error=====

我们还没有定义我们soc的相关信息，所以我们需要添加上去，同样的使用cp hi3516dv300.json xingyunnand.json得到我们的soc相关配置信息文件

{
   
   
    "device_name": "hi3516dv300", //同文件名,xingyunnand.json
    "device_company": "hisilicon", //device目录下的xingyunelec
    "target_os": "ohos",
    "target_cpu": "arm",
    "kernel_version": "",
    "device_build_path": "device/board/hisilicon/hispark_taurus/linux", //修改成自己对应即可
    "enable_ramdisk": true
}

修改成我们对应的相关配置信息，

{
   
   
    "device_name": "xingyunnand",
    "device_company": "xingyunelec",
    "target_os": "ohos",
    "target_cpu": "arm",
    "kernel_version": "",
    "device_build_path": "device/xingyunelec/xingyunnand/sdk_linux",
    "enable_ramdisk": true
}

然后使用 ./build.sh --product-name zxyNandst –ccache 再次编译试试，还是报错了，报错信息如下。
