PanGu board support multi operating system, developers can easily choose the development methods and environments that they are familiar with.
At the same time, due to the increasing demand for functions, the PanGu development board also supports a multi-language operating environment, which makes it easier for developers to deploy applications in different languages on the platform, and to better characterize different languages in the application scenario. .
Supported OS
Debian 9 Stretch
Yocto Linux with Qt5 GUI framework
Yocto Linux with Weston GUI framework
