Mikroe Clicker RA4M1

Overview

The Mikroe Clicker RA4M1 development board contains a Renesas Cortex-M4 based R7FA4M1AB3CFM Microcontroller operating at up to 48 MHz with 256 KB of Flash memory and 32 KB of SRAM.

Hardware

The Clicker RA4M1 board contains a USB Type-C connector, two LEDs, two push buttons, and a reset button. It has J-Link onboard and mikroBUS socket for interfacing with external electronics. For more information about the development board see the Clicker RA4M1 website [1].

Supported Features

The Zephyr Mikroe Clicker RA4M1 configuration supports the following hardware features:

Interface	Controller	Driver/Component
NVIC	on-chip	nested vector interrupt controller
UART	on-chip	serial port-polling
PINMUX	on-chip	pinmux
GPIO	on-chip	GPIO output GPIO input

Other hardware features have not been enabled yet for this board.

The default configuration can be found in the defconfig file: boards/mikroe/clicker_ra4m1/mikroe_clicker_ra4m1_defconfig.

Programming and debugging

Building & Flashing

You can build and flash an application in the usual way (See Building an Application and Run an Application for more details).

Here is an example for building and flashing the Blinky application.

# From the root of the zephyr repository
west build -b mikroe_clicker_ra4m1 samples/basic/blinky
west flash

Debugging

Debugging also can be done in the usual way. The following command is debugging the Blinky application. Also, see the instructions specific to the debug server that you use.

# From the root of the zephyr repository
west build -b mikroe_clicker_ra4m1 samples/basic/blinky
west debug
