RK3568开发板安卓系统之建立新产品配置（二）_专栏

2 建立新产品配置

2.1 建立产品dts

产品新建dts可以选择rk3568-evb1-ddr4-v10.dts作为参考,拷贝rk3568-evb1-ddr4-v10.dts为rk3568-aybering.dts, 然后修改Makefile

hale@thinkpad:rk3568_aybering_Android11$ cp kernel/arch/arm64/boot/dts/rockchip/k3568-evb1-ddr4-v10.dts kernel/arch/arm64/boot/dts/rockchip/rk3568-aybering.dts

2.2 建立产品lunch

以RK356x平台新建 rk3568_aybering 产品为例，分以下步骤：

2.2.1 修改device/rockchip/rk356x/AndroidProducts.mk增加rk3568_aybering的lunch

diff --git a/device/rockchip/rk356x/AndroidProducts.mk b/device/rockchip/rk356x/AndroidProducts.mk

2.2.2 在device/rockchip/rk356x目录下新建rk3568_r目录

参考device/rockchip/rk356x下已有的rk3568_r产品目录新建，可以先直接拷贝rk3568_r为rk3568_aybering，然后将rk3568_aybering目录下的所有rk3568_r字符改为rk3568_aybering

2.2.3 再次执行lunch命令即可看到新增的产品

hale@thinkpad:rk3568_aybering_Android11$ lunch 

You're building on Linux

Lunch menu... pick a combo:
    ...
     52. rk3566_rgo-user
     53. rk3566_rgo-userdebug
     54. rk3568_aybering-user

     56. rk3568_r-user

2.2.4 再次完整编译

hale@thinkpad:rk3568_aybering_Android11$ ./build.sh -UCKAup

期间，会再次弹出电压域配置窗口
