Renesas:RXHEW

Introduction

Software development in C on Serious Integrated Modules (SIMs) using the Renesas RX600 series MCUs requires three main components:

• An Integrated Development Environment (IDE)
• A C compiler suite
• A programmer/debugger device with drivers

There are three main IDEs available:

• The free Renesas High-performance Embedded Workshop (HEW)
• The free Renesas Eclipse-based E2Studio
• The full-featured commercial IAR Embedded Workbench for Renesas RX

This guide covers the HEW installation.

There are three main C Compilers available:

• The free (fully unlocked) KPIT Cummins GNU C compiler
• The high performance, full-featured, and commercially supported Renesas RX Compiler
• The high performance, full-featured, and commercially supported IAR Compiler in the IAR Embedded Workbench for Renesas RX

This guide covers the KPIT GNU C installation.

There are several debugger/programmer solutions, requiring both the hardware debug adapter plus appropriate software drivers:

• Renesas E1 debugger
• Renesas E20 debugger
• Segger J-Link
• Segger J-Link LITE RX

All of these debuggers are covered in this guide.

Installing HEW

HEW runs on Windows XP, Vista and 7 platforms. Please consult the Renesas HEW website for complete system requirements.

Renesas HEW IDE is not available for download as a standalone item. Instead, you must download the complete build from a starter kit or development kit. These instructions use the release image for the YRDKRX63N starter kit.

1. Download the YRDKRX63N Installation ZIP to your PC and extract it.
2. Run the install program autorun.exe from the DVD10 folder to install HEW. DO NOT INSTALL the KPIT GNU Compiler from the YRDKRX63N installation files: the version included in the YRDKRX63N installation may be out of date. Also, you will need an activation key from KPIT Cummins. After the base HEW IDE is installed we'll cover how to get and install the latest KPIT GNU C compiler suite.





3. Install the YRDKRX63N with the rest of the settings as default.

Updating HEW

Once HEW is installed, you will need to update it to the latest revision. This will enable new features and new microprocessor support for the RX63x series as well.

1. Download the latest updater for HEW at the Renesas HEW update website
2. Follow the install directions and update your HEW install to the latest version.

Installing the KPIT GNU C Compiler

For C-based development, including using SHIPWare, you will need a C Compiler. The no-cost GNU C/C++ compiler from KPIT Cummins includes full plug-in compatibility with the Renesas HEW IDE.

1. Register with KPIT and get an activation code before you can download and install the tools; it may take 24 hours to get access and a code.
2. Once you have your activation code, log into the KPIT website, and navigate to the Free Downloads->KPIT GNU Tools area.

3. Select the GNURX vXX.XX Windows Tool Chain (ELF) download

4. Run the downloaded installer. Default settings are usually sufficient for the installation.

Installing the Hardware Programmer/Debugger Drivers

Now that HEW and GNURX Toolchain are installed, you can now install the hardware debugger software drivers.

At this point you have a few options in selecting the hardware debugger. This installation guide will go over the Renesas E1/E20 and the Segger J-Link/J-Link Lite installation. The Renesas E1 debugger, the Segger JLink and the Segger JLink-Lite debugger are all used in the development of Serious products.

We recommend you install drivers for both the E1 and JLink.

Installing the Renesas E1/E20 Debugger Drivers

Full information on the Renesas debuggers can be found here.

1. Download the latest driver software for the E1 or E20.
2. Run the installer.
3. The HEW Install Manager will also be installed with the RX E1/ED20 Emulator Debugger along with the E-Series USB Drive and an Auto-Update utility. Go ahead and install all those items as well.

Installing the Segger JLink Debugger Drivers

The Segger J-Link and J-Link LITE RX debuggers are great, cost-effective debugger solutions, and are included with many SIM bundles.

Full information about the Segger J-Link debuggers for the Renesas RX can be found here.

The Segger J-Link Driver install is actually a two part download/install process. You must install both parts in the exact sequence described below.

Segger Install Part 1 (HEW Registration)

This step notifies HEW about the Segger debugger(s). You only need to do this step the first time you install Segger tools into HEW. If you are updating your Segger driver, you can skip this step.

1. Download the J-Link HEW Registration Utiility
2. Run this installer

Segger Install Part 2 (Drivers)

In this step, we'll install the latest drivers for the Segger debugger(s).

Make sure you use v4.73c or later -- prior versions had issues with the RX63x support as well as RX Sleep Mode.

1. Download the latest J-Link RX Software Package

2. Run the Setup_JlinkRX_Vxxx.exe installer. Use the default settings and do not click on the other boxes as it will overwrite the entries for other debuggers!

3. The Segger J-Link RX DLL Updater will also get installed as a Windows application. Click on the Windows Start button, find SEGGER->JLink RX VX.xxx folder and run the Segger J-Link RX DLL Updater program. You may see a screen again similar to above. Click OK and the application will install/update the DLLs for HEW.
4. Reboot your PC. It has been experienced at Serious where the installation process leaves a side-effect that causes Windows to get confused where Explorer shortcuts are located, and a proactive reboot avoids this issue.

Installation Complete

You should now have everything installed and ready to run HEW.

For starting up HEW and loading SHIPWare on your SIM product, please consult the “Getting Started Guide” located in the SHIPWare distribution docs folder.
