Make Example, the last one “vendor-rockchip-common”
https://github.com/rockchip-toybrick/?q=vendor-rockchip-common&type=&language=&sort=
This project seems renamed to rk_platform_vendor_rockchip_common (https://github.com/rockchip-toybrick/rk_platform_vendor_rockchip_common)
It is hard to skip every missing git and make compilation success.
Or you could provide new manifest.xml which on your manifests git without missing git error and could compile success.
It is easier and better to just provide one tar file which contains all source code for us.
Thanks
