The Reference Design Kit (RDK) stack is broadly categorized into software/firmware coming from the RDK Developer community, OEM’s and hardware dependant code from SoC vendors. Community is responsible for releasing the Generic RDK code which is mainly making use of Open source software for their adaptability and ease of improvement. OEM’s generally provide software’s such as bootloader, secure storage management etc. The Linux kernel and associated drivers are contributed by SoC vendors. RDK components are designed in such a way that any platform change or modifications in other component will not affect the total system as a whole and would not require much effort to integrate.
Over the years the generic RDK layer is growing which indicates more added features and more open-sourced components.
