Overview

The Renesas RA6E1 group uses the high-performance Arm® Cortex®-M33 core with TrustZone®. The RA6E1 is suitable for entry IoT applications requiring streamlined feature and connectivity integration including Ethernet, and unprecedented performance with 790.75 CoreMark, which are 3.95CoreMark / Mhz.

The key features of the FPB-RA6E1 board are categorized in three groups as follow:

MCU Native Pin Access

• 200MHz Arm Cortex-M33 based RA6E1 MCU in 100 pins, LQFP package
• Native pin access through 2 x 50-pin male headers (not fitted)
• MCU current measurement point for precision current consumption measurement
• Multiple clock sources - Low-precision (~1%) clocks are available internal to the RA MCU. RA MCU oscillator and sub-clock oscillator crystals, providing precision 24.000 MHz (not fitted) and 32,768 Hz reference clocks are also available

System Control and Ecosystem Access

• Two 5V input sources

  • USB (Debug, Full Speed, High Speed)
  • External power supply (using 2-pin header) (not fitted)

• Built-in SEGGER J-Link Emulator On-Board programmer/debugger (SWD)

• User LEDs and buttons

  • Two User LEDs (green)
  • Power LED (green) (not fitted) indicating availability of regulated power
  • Debug/power LED (yellow) indicating power and the debug connection
  • One User button
  • One Reset button

• Two popular ecosystems expansions

  • Two Digilent PmodTM (SPI, UART) connectors (not fitted)
  • Arduino (Uno R3) connector

• MCU boot configuration jumper

Supported Features

.. zephyr:board-supported-hw::

Programming and Debugging

.. zephyr:board-supported-runners::

Applications for the fpb_ra6e1 board target configuration can be built, flashed, and debugged in the usual way. See :ref:build_an_application and :ref:application_run for more details on building and running.

Flashing

Program can be flashed to FPB-RA6E1 via the on-board SEGGER J-Link debugger. SEGGER J-link's drivers are available at https://www.segger.com/downloads/jlink/

To flash the program to board

1. Connect to J-Link OB via USB port to host PC

2. Make sure J-Link OB jumper is in default configuration as describe in FPB-RA6E1 - User's Manual_

3. Execute west command

   .. code-block:: console

   Copy

    west flash -r jlink
   

Debugging

You can use Segger Ozone (Segger Ozone Download_) for a visual debug interface

Once downloaded and installed, open Segger Ozone and configure the debug project like so:

• Target Device: R7FA6E10F
• Target Interface: SWD
• Target Interface Speed: 4 MHz
• Host Interface: USB
• Program File: <path/to/your/build/zephyr.elf>

Note: It's verified that we can debug OK on Segger Ozone v3.30d so please use this or later version of Segger Ozone
