Open Firmware Boot Firmware for StrongARM
System ROM Code
An Open Firmware boot firmware implementation for the StrongARM processor is
now available from FirmWorks. This implementation is the recommended
firmware implementation for use on the
Digital Network Appliance
Open Firmware, formally described by IEEE Standard
1275-1994, is the first non-proprietary open-standard boot
firmware that is usable on different processors and buses.
Open Firmware includes:
- A processor-independent "device interface" that enables an add-in
peripheral card to identify itself and to supply a single boot driver
that can be used, unchanged, on any CPU using Open Firmware.
- A "user interface" with powerful scripting and debugging capabilities.
- A "client interface" that enables operating systems and their
loaders to make use of Open Firmware services to assist in the
configuration and initialization process.
FirmWorks's Open Firmware implementation for StrongARM complies with:
- IEEE Std 1275-1994 Standard for Boot (Initialization
Configuration) Firmware: Core Requirements and Practices
- ARM Processor Binding Specification
- Digital Network Architecture Platform Binding Specification
- PCI Binding Specification
This implementation supports:
- SA-110 Processor
- PCI, ISA and other buses
The core technology of FirmWorks's Open Firmware is a small, fast, efficient
Forth micro-kernel enabling powerful, interactive debugging and
automated system configuration.
This mature code is based on a field-proven implementation and can be
easily ported to your specific system architecture.
- Provides machine-independent configuration and booting support for
- Provides a framework for plug-in drivers so that user-installed
peripherals boot "out-of-the-box".
- Provides a standard set of firmware functions for use by "client
programs": operating systems, loaders, diagnostics, etc.
- Provides complete run-time configuration information to client programs.
- Contains a full ANS Forth interpreter for interactive programming,
debugging and configuration.
- Off-the-shelf drivers are available
for many commonly-used devices. (And, if we don't have what you need,
we can create it for you easily.)
Technical Support Available:
- Source code licenses and object code distribution licenses are available.
