1 Overview

1.1 Introduction

Thank you for purchasing Tornado!

Tornado 2.2 provides a greater level of accessibility for users unfamiliar with Tornado, and increased productivity for experienced developers. Key features of this release are:

the integrated version of the VxWorks target simulator (VxSim) introduced in Tornado 2.0

the integrated version of the WindView logic analyzer for the target simulator introduced in Tornado 2.0

an improved project facility

a new debugger engine

The target simulator allows you to experience Tornado -- as well as begin developing hardware-independent modules -- without target hardware. The integrated version of WindView provides dynamic visualization of application behavior on the simulator. The new project facility provides automated graphical features for managing project files, configuring VxWorks, and building applications. The new debugger GUI is easier to use and provides more direct access to debug information.

This guide describes how to install Tornado and other compatible products. It also provides a simple tutorial that demonstrates the use of the project facility, the integrated versions of the target simulator and WindView, and the Tornado debugger. The tutorial is designed to provide new users with an accessible introduction to the key features of Tornado and their use in application development. It is also intended to provide experienced Tornado users with an introduction to major innovations in the development environment.

NOTE: The integrated target simulator (VxSim-Lite) runs as a single instance per user, without networking support. Optional products such as SNMP and other network products are not available for this version. The full-scale version of the simulator, VxSim, is available as an optional product. It supports multiple-instance use, networking, and other optional products.

The integrated version of WindView is designed solely for use with the VxWorks target simulator. WindView is available as an optional product for all supported target architectures.

1.2 Terminology and Conventions

The following terms are used in this document:

host

A computer on which the Tornado development tools run.

target

A processor board that runs VxWorks (Tornado's real-time operating system) and applications developed with Tornado.

target server

A service that runs on the host and manages communications between host tools (such as the Tornado shell, debugger, and browser), and the target system itself. One target server is required for each target.

Tornado registry

A Tornado service that keeps track of, and provides access to, target servers. One registry may serve a network, or registries may run on each Tornado host.

The following conventions are used in this document:

The root installation directory is identified as installDir in this document, but the environment variable WIND_BASE must be set to the root installation directory for Tornado to work.

A series of items to be selected from the GUI is denoted by A>B>C. The elements A, B, and C may be menu items, buttons, or tabs.
