Introduction

1.3 Tornado* for I20* Software Development Toolset

Tornado for I20 is a complete toolset featuring an integrated development environment i ncluding a

compiler, assembler, linker, and debugger. It also features a real-time operating system.

1.3.1 IxWorks* Real-Time Operating System

The IQ80960RM/RN platforms are equipped with Wind River Systems, Inc.’s IxWorks*. IxWorks

provides for the el ements of the I2O standard: an even t-driven driver fr amework, host mes sage

protocols, and executive modules for configurati on and control. IxWorks also allows for the

writing of basic device drivers and provides NOS-to-driver independence. TORNADO for I2O

provides a visual environment for building, testing and debugging of I2O drivers.

1.3.2 TORNADO Build Tools

TORNADO for I2O includes a collection of supporting tools that provide a complete development

tool chain. These include the compiler, assembler, linker and binary utilities. Also provided is an

I2O module builder, which creates I2O-loadable modules.

1.3.3 TORNADO Test and Debug Tools

TORNADO for I2O test and debug tools include th e dynamic l oader, the CrossWind∗ debugger, the

WindS h* interactive shell, and a syst em browser.

The dynamic loader allows for interactive loading, te sting, and replacement of individual object

modules that comprise a driver.

CrossWind is an extended version of GDB960. Using it you can debug I2O drivers by setting

breakpoints on desired I2O components. A variety of windows display source code, registers,

locals, stack frame, memory and so on.

WindSh allows you to communicate to the IQ80960RM/RN platform via an RS-232 serial port.

The IQ80960RM/RN platform supports port speeds from 300 to 115, 200bps. The shell can be

used to:

•control and monitor I2O drivers

•format, send and receive driver messages

•examine hardware registers

•run automated I2O test suites

The shell also provides essential debugging capabilities; including breakpoints, single stepping,

stack checking, and disassembly.
