一、卷首

在开启一个新的android案子时，为了和原有项目区分开，一般均需要创建新产品自己的device或者Product目录。本文即以全志H713平台为例子，介绍新增一个名为myboard的产品。同时因为其派生自公版h713-tuna_p3，所以将其源码目录命名为h713-tuna_p3_myboard。

二、新增device目录

2.1 基本信息

• 确定产品基于device/softwinner/ares/h713-tuna_p3，也就是和h713-tuna_p3比较像
• 新board，或者新产品的名字叫：h713-tuna_p3_myboard

2.2 操作步骤

（1）cp -rf h713-tuna_p3 h713-tuna_p3_myboard ，可对比类似产品，看是否有Product差异配置，本案例此处完全相同
（2）cp h713_tuna_p3.mk h713_tuna_p3_myboard.mk，同理，本案例需修改
（3）编辑h713_tuna_p3_myboard.mk
（4）编辑AndroidProducts.mk，新增产品选项

2.3 编辑h713_tuna_p3_myboard.mk

• 新增并修改A:\works\aw\android\device\softwinner\ares\h713_tuna_p3_myboard.mk
• 通过和相似产品的mk文件进行对比，即可得知需要配置的项目
• 修改项目如下

PRODUCT_NAME := h713_tuna_p3_myboard
PRODUCT_DEVICE := h713-tuna_p3_myboard
PRODUCT_BOARD := tuna_p3_myboard
PRODUCT_MODEL := QUAD-CORE h713 tuna_p3_myboard

2.4 编辑AndroidProducts.mk

• 如下，增加如下修改

diff --git a/device/softwinner/ares/AndroidProducts.mk b/device/softwinner/ares/AndroidProducts.mk
index 7a48abbb78..b3e7173f32 100644

+    h713_tuna_p3_myboard-user \h713m_tuna_p3-userdebug \h713m_tuna_p3-user \h716m_tuna_p3-userdebug \

三、新增内核配置

3.1 新增config目录

• 产品派生自tuna_p3公版，所以直接复制即可

cd longan/device/config/chips/h713/configs/
cp -rf  tuna_p3  tuna_p3_myboard

3.2 新增defconfig文件

• 产品派生自tuna_p3公版，所以直接复制即可

cd longan/kernel/linux-5.4/arch/arm/configs/
cp sun50iw12p1smp_android_tuna_defconfig  sun50iw12p1smp_android_tuna_myboard_defconfig

• 同时修改 configs\tuna_p3\android\BoardConfig.mk，将defconfig执行我们新增的这个配置：

LICHEE_KERN_DEFCONF:=sun50iw12p1smp_android_tuna_myboard_defconfig

四、差异列表

4.1 git add 之前
