Renesas Synergy™ Platform
3. Getting Started with Embedded Application Development on DK-S128
To develop and execute embedded applications on the DK-S128 using the Synergy Platform, Synergy
Software Package and development tools are required to be installed on your computer.
Step 1: Create My Renesas Account (if you do not have one already)
You need a My Renesas account to download software, development tools, and application projects. Log in
to or Sign up for a My Renesas account at
Step 2: Download and Install Synergy Software Package and Development Tools
The Synergy Software Package, J-Link USB drivers, and one of the two supported tool chains are bundled
and available as single downloadable file as follows:
A. IAR Platform Installer installs Synergy Software Package and IAR Embedded Workbench
Renesas Synergy™ IDE with IAR complier and J-Link USB drivers.
Download from www.renesas.com/synergy/ewsynergy.

B. e
studio Platform Installer installs Synergy Software Package and e
IAR complier and J-Link USB drivers.
Download from www.renesas.com/synergy/e2studio.
Note: The DK-S128 uses J-Link
establish debug connection between the host PC and the DK-S128, they are not required to run the
Out-of-Box (OoB) Demonstration Application that the DK-S128 comes pre-programmed with. Refer to
the DK-S128 Quick Start Guide for more details.
Step 3: Explore Existing Application Projects for the DK-S128
Renesas provides several application projects to demonstrate different capabilities of the S128 MCU Group.
These application projects can also serve as a good starting point for you to develop your custom
applications. Application projects available for the DK-S128 are listed at www.renesas.com/synergy/dk-s128.
Notes: 1. Every application project includes the project files, an application note, and instructions to import
the application project.
2. On downloading the application project from the website to your computer, the application projects
have to be built using one of the two supported tool chains before they can be downloaded on to
the DK-S128 board.
4. DK-S128 Hardware Details
4.1 Jumpers and DIP Switch Settings
4.1.1 Default Board Configuration
The Circuit Group for each jumper is the designation found in the board schematic. See section 6, Electrical
Schematics. Functional details for many of the listed jumpers may be found in section 5.4, Connectivity and
Settings. The following table describes the default settings for each jumper on the DK-S128.
