The flexible software package (FSP) is the basic building block of RA software. Out of the box, FSP offers Amazon FreeRTOS® along with basic HAL drivers, middleware stacks, and board support packages. Going forward, there will be more RTOS that will be supported. The RA hardware abstraction layer (HAL) offers high performance and highly efficient drivers optimized to the hardware with portable APIs. TrustZone® features are also integrated in the FSP. All this software will be on GitHub, and the full source code is licensed to use on Renesas RA hardware only. FSP is also supported through user manuals, API documentations, application notes, and sample codes.
