RA6E1 Fast Prototyping Board

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

Programming and Debugging

Applications for the fpb_ra6e1 board target configuration can be built, flashed, and debugged in the usual way. See Building an Application and Run an Application 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 avaialbe 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

    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
