Technical Guide

Introduction

This document describes the Linux features specific to the SH7670 CPU and the RSK+ development board. The SH7670

RSK+ BSP is distributed as a compressed tar archive. During this document, you will create a tool chain, and build a

working environment for the SH7670 RSK+. This document assumes the reader has a basic knowledge of Linux.

Requirements

• To work with the SH7670 RSK+ BSP, you will need a Windows Host environment, and a GNU/Linux

Development Environment.

• The Renesas High Performance Embedded Workshop (HEW) runs in a Windows environment, and needs to be

installed to facilitate the downloading of images to the RSK+ board using a Renesas E10A.

• To build and develop on the µClinux environment, you will need a Linux development machine. This can be a

second physical machine, or a virtual machine sharing the Windows environment.

On a clean Ubuntu distribution, packages must be added to support this build process.

You will need to enter the following commands, or ensure the following packages are installed if you use a different

distribution.

sudo apt-get install gcc

sudo apt-get install build-essential

sudo apt-get install ncurses-dev

sudo apt-get install mtd-tools

The BSP was compiled with gcc4.0 though gcc >4.0 should work but hasn’t been tested.

The Linux development environment will require at least 1.0 GB of free space.

This document is based on work completed using Ubuntu 8.04 default install with the above packages as the development

environment, and an SH7670 RSK+ development board (issue 1). Other Linux distributions may be used, but please be

aware of slight differences that may occur in command usage and package management.
