ARM

G.1 Introduction

Tornado for ARM provides the Tornado development tools and the VxWorks RTOS for the Advanced RISC Machines (ARM) family of architectures. ARM is a compact core which operates at a low power level. In addition to the standard 32-bit instruction set, it is available with a 16-bit instruction set (the Thumb instruction set), which permits applications to be developed with very compact code.

This appendix provides information specific to VxWorks development on ARM targets. It includes the following topics:

Building Applications: how to compile modules for the ARM architecture.

Toolchain Information: updates to the assembler, CrossWind, and the included toolchain files not yet included in GNU ToolKit or Debugging with GDB.

Interface Changes: information on changes or additions to particular VxWorks features to support the ARM processors.

Architecture Considerations: special features and limitations of the ARM processors, including a figure showing the VxWorks memory layout for these processors.

For general information on the Tornado development environment's cross-development tools, see the Tornado User's Guide: Projects.
