What’s in this package

With GNUPro Toolkit, Cygnus Solutions provides software development tools and component technologies for systems using 32- and 64-bit microcontrollers.

GNUPro Toolkit includes a C/C++ compiler, a powerful source-level debugger with a graphical user interface, an assembler, a linker/loader, binary file utilities, and libraries. See The components of GNUPro Toolkit for more overview of the tools.

Complete source code, tested binaries, and product documentation accompany the tools.

Customers are free to copy and redistribute these components as they see fit.

Cygnus Solutions provides support services that can be scaled up to meet any organization’s requirements, providing mission-critical support services (rapid response and resolution of technical questions or problems) as well as regular software upgrades.

While the software is free, the solutions cost. The services are based on a fixed-fee, fixed-time basis (usually annual), priced according to the level of support offered and the number of developers using the tools for business-related purposes.

Over 200 companies have chosen GNUPro Toolkit based on the following criteria.

- Single-source solutions and broadest host-target coverage, enabling true multiplatform development and easy retargeting of development
- Superior code generation technology
- Easy license terms and no license manager
- Fast tools availability for the latest microcontroller architectures
- Flexible software customization services

Not all tools are available for all platforms and operating systems. See Embedded Configurations Supported, Specific Processor Support by Family and Native Configurations Supported in Release Notes for GNUPro Toolkit for an up-to-date matrix with current host/target combinations supported by Cygnus Solutions. Also, see Using the GNU Tools on Embedded Systems in GNUPro Tools for Embedded Systems for specific information on your system.

The accompanying documentation, in this release, has undergone some radical changes in naming and location. See GNUPro Toolkit Documentation for the current documentation as well as Using the Current Documentation.
