RA6M5 Evaluation Kit
|
|
####################
|
|
|
|
Overview
|
|
********
|
|
|
|
The Renesas RA6M5 group uses the high-performance Arm® Cortex®-M33 core with
|
|
TrustZone®. The RA6M5 is suitable for IoT applications requiring Ethernet, future
|
|
proof security, large embedded RAM, and low active power consumption down
|
|
to 107uA/MHz running the CoreMark® algorithm from Flash.
|
|
|
|
The key features of the EK-RA6M5 board are categorized in three groups as follow:
|
|
|
|
**MCU Native Pin Access**
|
|
|
|
- 200MHz Arm Cortex-M33 based RA6M5 MCU in 176 pins, LQFP package
|
|
- Native pin access through 4 x 40-pin male headers
|
|
- MCU current measurement points for precision current consumption measurement
|
|
- Multiple clock sources - RA6M5 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 RA6M5 MCU
|
|
|
|
**System Control and Ecosystem Access**
|
|
|
|
- USB Full Speed Host and Device (micro-AB connector)
|
|
- Four 5V input sources
|
|
|
|
- USB (Debug, Full Speed, High Speed)
|
|
- External power supply (using surface mount clamp test points and power input vias)
|
|
|
|
- Three Debug modes
|
|
|
|
- Debug on-board (SWD)
|
|
- Debug in (ETM, SWD and JTAG)
|
|
- Debug out (SWD)
|
|
|
|
- User LEDs and buttons
|
|
|
|
- Three User LEDs (red, blue, green)
|
|
- Power LED (white) indicating availability of regulated power
|
|
- Debug LED (yellow) indicating the debug connection
|
|
- Two User buttons
|
|
- One Reset button
|
|
|
|
- Five most popular ecosystems expansions
|
|
|
|
- Two Seeed Grove system (I2C/Analog) connectors
|
|
- One SparkFun Qwiic connector
|
|
- Two Digilent Pmod (SPI and UART) connectors
|
|
- Arduino (Uno R3) connector
|
|
- MikroElektronika mikroBUS connector
|
|
|
|
- MCU boot configuration jumper
|
|
|
|
**Special Feature Access**
|
|
|
|
- Ethernet (RJ45 RMII interface)
|
|
- USB High Speed Host and Device (micro-AB connector)
|
|
- 32 Mb (256 Mb) External Quad-SPI Flash
|
|
- 64 Mb (512 Mb) External Octo-SPI Flash
|
|
- CAN (3-pin header)

Programming and Debugging
|
|
*************************
|
|
|
|
Applications for the ``ek_ra6m5`` 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 EK-RA6M5 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 `EK-RA6M5 - 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: R7FA6M5BH
|
|
* 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
