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
|
|
: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 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-RA6E2 - User's Manual`_
|
|
|
|
3. 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
