RZ/A2M Software Package is a software development kit for the RZ/A2M that supports various RZ/A2M functions such as DRP(Dynamically Reconfigurable Processor), camera input, LCD output, and image adjustment. It consists of device drivers, middleware, sample programs for the RZ/A2M and FreeRTOS OS.


In addition to the RZ/A2M Software Package GCC version, the Arm Compiler version is also available for customers who prefer to use the Arm's integrated development environment (Arm Development Studio : Arm DS).
