Overview
Description
The EK-RA6M5 evaluation kit enables users to effortlessly evaluate the features of the RA6M5 MCU Group and develop embedded systems applications using the Flexible Software Package (FSP) and e2 studio IDE. Utilize rich on-board features along with your choice of popular ecosystem add-ons to bring your big ideas to life.
Getting Started
Running the Quick Start Example Project
- The EK-RA6M5 comes pre-programmed with a quick start example project (source code provided in the EK-RA6M5 Example Project Bundle).
- Power up the EK-RA6M5 board through the debug USB port (J10) using the micro USB device cable connected to a 5V power source. The white power LED will light up.
- The quick start example project will begin to execute blinking the blue user LED.
- Refer to the EK-RA6M5 Quick Start Guide to explore additional functionality of the quick start example project.
Developing Embedded Applications
- Modifying the quick start example project – refer to the EK-RA6M5 Quick Start Guide for instructions on importing, modifying, and building the quick start example project
- Start with one of the many other example projects – choose from many example projects provided in the EK-RA6M5 Example Project Bundle to learn about different peripherals of the RA6M5 MCU Group. These example projects can serve as excellent starting points for you to develop your custom applications.
Building a Custom Hardware
- Start by building a functional prototype – utilize the EK-RA6M5 board with your choice of hundreds of popular ecosystem add-ons.
- Build custom hardware – develop custom hardware by referring to the design and manufacturing information provided in the EK-RA6M5 Design Package.

Design & Development
Videos & Training
Learn how we access Octal SPI flash on the RA6M5 Evaluation Kit to perform data operations in multiple modes. We will outline how the Octal SPI peripheral communicates with external OctaFlash and OctaRAM devices, and demonstrate erase, write, and read operations in both SPI mode and Single OPI mode.
