####################
|
|
|
|
Overview
|
|
********
|
|
|
|
The Renesas RA4W1 is the first Bluetooth® 5.0 Low Energy fully compliant with 2Mbit High-Throughput
|
|
(HT) and Long Range support in a single chip MCU of Renesas RA4 product series for IoT applications
|
|
that require a high-performance Arm® Cortex®-M4 core at a very attractive price point. The RA4W1 MCU
|
|
has full function support for Bluetooth 5.0 Low Energy long-range and mesh networking, and provides
|
|
excellent reception performance. RA4W1 is geared towards IoT application requiring Security, large
|
|
embedded RAM and low power consumption.

Programming and Debugging
|
|
*************************
|
|
|
|
Applications for the ``ek_ra4w1`` 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-RA4W1 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-RA4W1 - 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: R7FA4W1AD
|
|
* 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
