Overview

Introduction

RA4M1-Zero is a compact microcontroller development board with multiple digital interfaces. In terms of hardware, it uses a R7FA4M1AB3CFM chip, which is equipped with a Cortex-M4® 32-bit single-core processor, equipped with an FPU floating point unit, supports up to 48MHz clock frequency, and has a built-in 256KB ROM, 32KB SRAM and 8KB EEPROM. It is compatible with a variety of peripherals and makes it more convenient to use. As for the software, you can choose Arduino IED for development, making it easy and quick to get started and apply it to products.

Arduino Environment Setup

• Get Arduino IDE from the official website and select the ZIP file to download (for other system users, select the corresponding file to download)
  

• Download and extract the files, then open the extracted directory, double-click on Arduino IDE.exe, and download the board file needed for RA4M1-Zero
  

• After the download is completed, reopen Arduino IDE, create a new project --> Flash program --> Observe serial port
  

• If you see that the serial port outputs Hello, World every 1s, it means that the environment is successfully set up
  

Bootloader Firmware Download

• Download the corresponding Firmware Flashing Tool, after downloading and extracting successfully, enter the Renesas_Flash directory and double-click the exe file to install, and the installation process options remain the default
  

• After successful installation, go to the file in the previous step, enter the directory AWAA, double-click to open the AWAA.rpj tool to set the file
  

• Select Connect Settings on the toolbar, then press and hold the Boot button on the board, then press Reset button to enter the firmware download mode, and then select the corresponding COM port

• Select Operation from the toolbar, then click Add/Remove Files to add Firmware, and delete other unnecessary firmware

• Finally, click on Start and wait for the firmware download to complete. After the download is complete, unplug and plug in the USB again to power on
