Getting Started
Running the Quick Start Example Project
- The EK-RA4E2 board comes pre-programmed with a quick start example project (source code provided in the EK-RA4E2 example project bundle).
- Power up the EK-RA4E2 board through the USB debug 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-RA4E2 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-RA4E2 Quick Start Guide for instructions on importing, modifying, and building the quick start example project.
- Start with one of the many other example projects (provided in the EK-RA4E2 example project's bundle) – choose from many example projects to learn about different peripherals of the RA4E2 MCU group. These example projects can serve as excellent starting points for you to develop your custom applications.
Building Custom Hardware
- Start by building a functional prototype - utilize the EK-RA4E2 board with your choice of ecosystem add-ons.
- Build custom hardware – develop custom hardware by referring to the design and manufacturing information provided in the EK-RA4E2 design package.

AI-generated Summary:
MCUboot provides a secure bootloader framework for 32-bit MCUs, enabling secure booting and fail-safe firmware updates using internal code flash. It supports multiple update strategies including Overwrite, Swap, and Direct Execute-in-Place (DXIP), each with distinct advantages and trade-offs. The bootloader authenticates firmware images using RSA or ECDSA signatures and SHA-256 hashing. Integration with Renesas Flexible Software Package (FSP) simplifies creating a Root of Trust and supports TrustZone-based designs. Example projects demonstrate usage on EK-RA4M3 kits with FSP v5.2.0, covering multi-image and single-image configurations. Development requires e2 studio IDE, FSP, SEGGER J-Link, and Python. The document guides through project setup, bootloader creation, application signing, and update modes, providing a comprehensive framework for secure firmware management on Renesas RA MCUs.
