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 available 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

Supported Features

.. zephyr:board-supported-hw::

Programming and Debugging

.. zephyr:board-supported-runners::

Applications for the fpb_ra6e2 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-RA6E2 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

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

.. code-block:: console
```
 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
