Development Environment

The ChorusOS 5.0 product provides a host-target development environment. Applications are developed on a workstation (the host), and then downloaded and executed on a specific board (the target).

A cross development system is needed to build the applications that execute on the target board (see Section "Utilities").

Solaris^TM (SPARC^TM Platform Edition) Reference Host Environment

This section contains information on the requirements for the host system.

Prerequisites for the Solaris host reference configuration are the following:

• Sun SPARCstation^TM

• Solaris 7 (32-bit and 64-bit mode)

• Solaris 8 (32-bit and 64-bit mode)

• JDK 1.2 or higher for the graphical installer

• JDK 1.2 for the graphical configuration tool

• JDK 1.3 for the Java^TM applications (J2ME source Add-on)

Cross Compiler

This development environment component is bundled with the ChorusOS 5.0 for MPC8xx product:

• Chorus Cross Development System 6.0 for PowerPC.

The Chorus Cross Development System is based on the GNU Compiler gcc 2.97 and binutils 2.10.

Graphical Debugger

The ChorusOS 5.0 Cross Development System includes the GNU GDB debugger for ChorusOS with a graphical user interface Insight. Using this debugger you are able to debug ChorusOS applications and systems.

ChorusOS 5.0 Supported Features

The following table shows the ChorusOS kernel and operating system optional features that are available for the MPC8xx processor family. The availability status of a feature can be one of:

Y

The feature is supported, and is configurable using the configurator(1CC) command, or with the ews GUI configuration tool.

Please refer to the note at the end of the table for information about specific conditions, or restrictions, for a given supported feature.

Some of the features (such as MSDOSFS, FLASH, FS_MAPPER, for example) require specific low-level drivers. These features operate only on platforms which provide these drivers.

N

The feature is not available.
