Try FreeRTOS. A sample program called freertos_ek_ra6m2_ep is also provided, but this time a new program is created. Select Renesas RAC Executable Project. Select EK-RA6M2 for Board. For the RTOS, choose Amazon freeRTOS. Select a project that includes LED flashing. Generating and running the code was easy. I incorporated the board into the tapper.
