RA6E2 Fast Prototyping Board
Overview
The FPB-RA6E2, a Fast Prototyping Board for RA6E2 MCU Group, based on the 200 MHz Arm® Cortex®-M33 core with TrustZone, enables users to seamlessly evaluate the features of the RA6E2 MCU group and develop embedded systems applications using Flexible Software Package (FSP) and e2 studio IDE. The users can use rich on-board features along with their choice of popular ecosystems add-ons to bring their big ideas to life.
The key features of the FPB-RA6E2 board are categorized in three groups as follow:
MCU Native Pin Access
200MHz Arm Cortex-M33 based RA6E2 MCU in 64 pins, LQFP package
256 kB Code Flash, 40 kB SRAM
Native pin access through 2 x 32-pin male headers
MCU current measurement point for precision current consumption measurement
Multiple clock sources - RA6E2 MCU oscillator and sub-clock oscillator crystals, providing precision 24.000 MHz and 32,768 Hz reference clock. Additional low precision clocks are avaialbe internal to the RA6E2 MCU
System Control and Ecosystem Access
USB Full Speed Host and Device (micro-AB connector)
Two 5V input sources
USB (Debug, Full Speed)
External power supply (using 2-pin header)
On-board debugger (SWD)
User LEDs and buttons
Two User LEDs (green)
Power LED (green) indicating availability of regulated power
Debug/power LED (yellow) indicating power and the debug connection
One User button
One Reset button
Two popular ecosystem expansions
Two Digilent PmodTM (SPI, UART and I3C) connectors
Arduino (Uno R3) connectors
MCU boot configuration jumper

Programming and Debugging
Applications for the fpb_ra6e2 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-RA6E2 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
Connect to J-Link OB via USB port to host PC
Make sure J-Link OB jumper is in default configuration as describe in FPB-RA6E2 - User’s Manual
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: R7FA6E2BB
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
