The expansion board has no stand-alone capability and requires an RZ/N1D or RZ/N1S CPU board. On the
other side the RZ/N1L-DB board cannot be used together with the RZ/N1-EB board, as all interfaces are
already included on the CPU board.
The documentation for the expansion board including the setup notes and the schematics you may find under
YCONNECT-IT-RZN_V1.x\Documents\RZN.Boards\RZN1-EB.
1.7 Software
All RZ/N1x Solution Kits contain also a software release package that enables the user to evaluate various
functionalities of an advanced communication and processing device in the industrial automation industry. The
release package is also available for download on the Renesas RZ/N website. The software ecosystem of
RZ/N1 is broad and complex, due to different SW partners, several supported operating systems (OS), many
industrial real-time communication protocols, different development environments and a mixed feature support
of the three RZ/N1x CPU boards with or without the RZ/N1-EB expansion board. The software packages are
stored in the release directory YCONNECT-IT-RZN_V1.x\Software.
Documents for the software packages are available under the path YCONNECT-IT-
RZN_V1.x\Documents\RZN.Software\ and partially in the corresponding software directories.
Following is a short overview about the main software items of the RZ/N1x Solution Kits.
GOAL & Protocol Stacks
Coping with the real-time requirements and growing demands for Industrie 4.0 applications, Renesas provides
a variety of industrial real-time communication protocols that are implemented on communication module of
RZ/N1x –the Cortex M3 core in an effective combination with a 5-port switch and various accelerators. This
communication module inside the RZ/N1x is called R-IN Engine (Renesas Industrial Network Engine). With
this architecture the RZ/N1x devices are delivering a high performance, low power, enhanced and flexible
communication features to the outside world, which is independent from the applications side (RZ/1D and
RZ/N1S).
Based on these requirements the company port GmbH and Renesas have developed the Generic Open
Abstraction Layer (GOAL) middleware for Renesas R-IN Engine based processor families. The GOAL consists

of several layers of software for accessing the underlying R-IN platform resources, but also to access the
protocol stacks via dedicated APIs.
Out of the box the middleware provides support for:
•PROFINET, EtherCAT, EtherNet/IP, Modbus, POWERLINK and CANopen
•Supporting protocols such as TCP/IP (lwIP), SNMP, RSTP, etc.
•API for PHY and Switch Management
•Inter-processor communications (Core-to-Core, CTC) with shared memory, mailboxes, etc.
A variety of sample applications are delivered together with the GOAL software package explaining the basic
functionalities of the run-time system and show how to configure the different components and how to write a
GOAL based portable application. You may find the IAR GOAL sample projects in the directory YCONNECT-
IT-RZN_V1.x\Software\GOAL\projects\. As the R-IN Engine on the RZ/N1x boards are functionally identical
this GOAL package is covering all three boards with different IAR projects.
Figure 1-3 shows the file structure of the GOAL package on the release available in the directory YCONNECT-
IT-RZN_V1.x\Software\GOAL\.
Figure 1-3: GOAL File Structure (previous version)
Furthermore, GOAL middleware was ported to Linux, allowing the user to develop user space applications
using GOAL APIs. Additionally, with the Core2Core APIs the user could create communication channels for
message transmission between Cortex A7 and Cortex M3 core.

1.8 RZ/N1 Tools
Inside of the Solution Kit software package, Renesas is providing some tools which are useful for typical
programmers and designers to work with our platform. The directory in the release is …\YCONNECT-IT-
RZN_V1.x\Tools. The tools currently include the HTML-based PinMux tool, PC drivers, IBIS models (I/O Buffer
Information Specification) for RZ/N1x devices in different variants (BGA400, BGA324 and BGA196 packages)
and an IAR Embedded Workbench which can be used under a 30-days trial condition for the RZ/N1x Solution
Kit evaluation. Other tools, which are not included in this release, but might be of interest for the user, are
described in chapter 3 Miscellaneous Tools for Hardware and Software Development.
PinMux Tool
The PinMux Tool is used to support the customer with the pin multiplexing configuration, providing a graphical
user interface. The user specifies the peripheral signals and their respective external pinouts. This HTML
based application also detects and resolves conflicts in the configurations and it generates code (C header file
for U-Boot and GOAL, and device tree file for Linux) that is used to configure the device at initialization time.
The tool can be found under …\YCONNECT-IT-RZN_V1.x\Tools\PinMux.
It includes a light documentation “Quick Start” in its first “Package” tab. Following steps need to be done to
generate the pin multiplexing for a new RZ/N1 board. For the Solution Kit boards these steps has been done
already and the generated PinMux code is integrated into the SOFTWARE evaluation packages:
Step 1: Select the RZ/N1x device and device package you want to use on your board
Step 2: Pick all the peripherals you want to use on your board
Step 3: Map the GPIO to an interface function, or the interface function to the GPIO pin
Step 4: Check the RZ/N1 package footprint
Step 5: Generate the code used for the pin multiplexing in the start-up phase of your application
