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

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
++++++++++++++++++++++++++++++++++++++++2022-04-24 10:01:06--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。

接着再次编译，报错信息如下

vendor/xingyunelec/zxyNandst/hdf_config/uhdf/camera/pipeline_core/config.hcs文件、vendor/xingyunelec/zxyNandst/hdf_config/uhdf/camera/pipeline_core/params.hcs文件、vendor/xingyunelec/zxyNandst/hdf_config/uhdf/camera/pipeline_core/ipp_algo_config.hcs文件，再创建目录 vendor/xingyunelec/zxyNandst/hdf_config/uhdf/camera/driver,然后添加如下文件
vendor/xingyunelec/zxyNandst/hdf_config/uhdf/camera/driver/mpp_config.hcs，接着添加
vendor/xingyunelec/zxyNandst/hdf_config/uhdf/hdf.hcs,vendor/xingyunelec/zxyNandst/hdf_config/uhdf/device_info.hcs,注意修改hdf.hcs文件内容，不需要包含其他文件，像我这里就只包含了一个。
#include "device_info.hcs"root { module = "default";}然后再次执行 ./build.sh --product-name zxyNandst –ccache命令进行编译操作，

build/ohos/kernel/kernel.gni文件,修改点如下，这样就能编译我们自己的内核版本了。
diff --git a/build/ohos/kernel/kernel.gni b/build/ohos/kernel/kernel.gniindex d585469b4e..019c74745a 100644--- a/build/ohos/kernel/kernel.gni+++ b/build/ohos/kernel/kernel.gni@@ -11,5 +11,5 @@ # See the License for the specific language governing permissions and # limitations under the License. declare_args() {- linux_kernel_version = "linux-5.10"+ linux_kernel_version = "linux-5.4" }接着添加 kernel/linux/config/linux-5.4/目录，具体需要添加的文件路径以及名称为
kernel/linux/config/linux-5.4/arch/arm/configs/xingyunnand_standard_defconfig
其中 xingyunnand_standard_defconfig可以是 KaTeX parse error: Expected group after '_' at position 14: (DEVICE_NAME)_̲(BUILD_TYPE)_defconfig组成，
然后添加文件
kernel/linux/patches/linux-5.4/xingyunnand_patch/hdf.patch和kernel/linux/patches/linux-5.4/xingyunnand_patch/xingyunnand.patch两个文件，具体为什么添加这两个文件可以参考kernel/linux/build/kernel.mk文件，或者在编译的时候也会提示需要什么文件。然后把自己的内核源文件拷贝到kernel/linux/目录下，像我这里就是 kernel/linux/linux-5.4 目录，然后开始编译，编译结果如下图，可以看到其实uImage已经成功了，是在执行cp的时候出错了。
在 kernel/linux/build/build_kernel.sh文件中，有执行这个拷贝，目前不知道这是什么文件，我们暂时不用
直接注释掉，然后再次进行编译。
然后内核就编译好了，但是报错问题还是有，如下错误。

查看 drivers/peripheral/usb/hal/service/BUILD.gn文件，那么我们仿照着添加我们自己的即可。
添加好的文件修改补丁如下，

替换后的结果，替换成我们自己的路径即可。
