Quick Start Guide
1 INTRODUCTION
1.1 Overview
This document is a quick start guide for the GR-LEON4-ITX Development Board.
The purpose of this document is to get users quickly started using the board. For a complete
description of the board please refer to the GR-LEON4-ITX Development Board User
Manual, the LEON4 system-on-chip is described in the LEON4-ASIC-DEMO Data sheet and
User's Manual. This quick start guide does not contain as much technical details and is
instead how-to oriented. However, to make the most of the guide the user should have
glanced through the two aforementioned documents and should ideally also be familiar with
the GRMON debug monitor.
