NET+Works with Green Hills Programmer’s Guide

Overview

The NET+Works products offer an embedded solution for hardware and

networking software that are being implemented into product designs.

NET+Works is designed as an alternative to a PC for products that must be

connected to Ethernet for Transmission Control Protocol (TCP) access and for

Internet/Intranet access.

The NET+Works package includes:

 A NET+Works processor

 A development board and board support package

 Either a MAJIC/MAJICO debugger or a Raven debugger

 The networking firmware

 The object code with application program interfaces (APIs)

 Development tools

 Sample code

 Documentation

For information about the NET+ARM devices, see the hardware documentation.

System components

This section describes the components that make up the NET+Works software.

NET+Works runtime software

NET+Works software provides the building blocks to help you create your custom

applications. You create your application with calls to APIs for:

 The board support package (BSP)

 ThreadX RTOS kernel

 Basic Internet protocols

 Higher-level protocols and services

www.netsilicon.com

       3

NET+Works Introduction

Board support package

The NET+Works BSP is a collection of ARM object code and C source-code drivers

and bootloader. The BSP initializes hardware and software, and it provides power-

on self test (POST).

The BSP includes a set of APIs that you use to incorporate device peripheral

functionality into your application. In addition, the BSP provides the drivers for

your NET+ARM processor or Digi Connect module development board, including

Ethernet, Serial, SPI, Flash, USB host, USB device, LCD, PCI/CardBus, and others.

ThreadX RTOS kernel

The RTOS is based on a high-speed picokernel architecture. ThreadX helps you

manage complex event synchronization and memory using threads, queues,

application timers, semaphores, and event flags.

HTML-to-C compiler

The toolkit provides a compiler that translates your HyperText Markup-Language

(HTML) code into C code. You can then compile the C code as part of the project,

which allows you to create the pages your menu system needs to perform the tasks

necessary for your device. Sample code also is provided.

Advanced Web Server (AWS) PBuilder utility

Using the PBuilder utility, you create or maintain Web pages and recomplile the

application program to generate updated images. The PBuilder provides support for

HTML, multiple Web object sources, object compression, and advanced security.

Address Configuration Executive (ACE)

NET+Works provides services such as the ACE, which lets you acquire IP parameters

at startup from multiple prioritized sources, including BOOTP, RARP, Auto IP, and

others.

System requirements

NET+Works with Green Hills Programmer’s Guide

System requirements

To run NET+Works with Green Hills, your system must meet these requirements:

 A minimum of a 700 MHz Pentium processor and 256 MB of RAM. A 1.4 GHz

Pentium processor with 512 MB of RAM is recommended.

 A 256-color display, at a minimum resolution of 1024x768. A minimum

resolution of 1280x1024 is recommended.

 An Ethernet connection.

 1000 MB of free disk space per installation. If an older version of MULTI is

already installed on your machine, install this version in a different directory.

If you are installing to a drive other than your primary Windows drive, you also

must have at least 10 MB available on the primary drive for temporary files

and DLLs.

 A CD-ROM drive.

You need this software installed on your system:

 Internet Explorer 3.01 or later (to view online help).

 Microsoft Windows 2000 or XP

Requesting and Installing a

MULTI 2000 License

CHAPTER 2

Before you can use the MULTI 2000 software, you need to obtain and install

a software license from Green Hills. This chapter discusses licensing options,

provides licensing tips and recommendations, and describes how to request

and install a license.

Overview

6       

NET+Works with Green Hills Programmer’s Guide

Overview

Green Hills MULTI 2000 provides three licensing options: node-locked, floating, and

dongle-locked. The three license options are available as either evaluation or

permanent licenses.

After you install the Green Hills MULTI 2000 software, you request evaluation and

permanent licenses online. When you receive the key file, you save it to your hard

drive and then install it.

If you are installing floating licenses on Windows NT, Windows 2000, and Windows

XP clients, you need to perform some setup tasks that are specific the client

machine.

MULTI 2000 license options

This section describes the MULTI 2000 licensing options:

 Node-locked license

 Floating license

 Dongle-locked license

Node-locked license

A node-locked license is valid on the computer for which the license is issued. You

cannot move a node-locked license to another computer. Thirty-day evaluation and

permanent node-locked licenses are available.

Floating license

Floating licenses are stored on one or more license servers, and users can check

them out from anywhere on the network. Floating licenses allow you to add new

systems to your network or to have users move from system to system without re-

installing licenses on each machine.

www.netsilicon.com

       7

Requesting and Installing a MULTI 2000 License

Note, however, that you must install MULTI 2000 software on each machine that

needs to run that software. Thirty-day evaluation and permanent floating licenses

are available.

Dongle-locked license

A dongle is a hardware key that attaches to the parallel port of any machine,

giving that machine a MULTI 2000 license. The dongle can hold licenses for

multiple Green Hills products and can be moved to any computer. Thirty-day

evaluation and permanent licenses are available.

Request permanent licenses immediately

NetSilicon recommends that you request evaluation and permanent licenses at the

same time. Typically, Green Hills responds to node-locked evaluation license

requests (by email) within one business day. Floating evaluation licenses take

slightly longer, and dongle-locked licenses take several days longer still. Responses

to requests for permanent licenses typically take about 15 working days.

To avoid an interruption to your development work, NetSilicon recommends that

you begin the process of acquiring permanent licenses immediately.

Requesting a license

This procedure describes how to first request an evaluation license—so you can

begin development work almost immediately—and then a permanent license, which

can take up to 15 working days to process.

If you plan to request floating licenses, generate the license request on the system

that will be the license server.

If you plan to request node-locked licenses, generate the license request on each

system that will have a node-locked license.

X To request a license:

1 Select Start  Programs  Green Hills Software  MULTI for ARM v4.0.5-

NetSilicon Multi.

You will see the Multi launcher.

2 Select Utilities  License Administrator.

3 Follow the instructions using the Multi Licensing wizard.

Requesting a license for the Event Analyzer

NET+Works for NET+OS now supports the MULTI 2000 Event Analyzer, an option

that is not included in the NET+Works for NET+OS package. To obtain a license

for the Event Analyzer, either contact your local Green Hills office or go to

www.ghs.com.

Installing MULTI 2000 licenses

This section describes how to install a permanent license, which arrives as a .key

file that you must save to your disk.

Before you install — dongle-locked licenses only

If you requested dongle-locked licenses, make sure the dongle is securely attached

to the parallel port before you begin the license installation procedure.
