-
-The debugger uses an IEEE 1149-1 compliant JTAG TAP bus master to access on-chip
-debug functionality available on ARM7 and ARM9 based microcontrollers /
-system-on-chip solutions.
-
-User interaction is realized through a telnet command line interface and a gdb
-(The GNU Debugger) remote protocol server.
-
-1. JTAG hardware
-
-Currently, OpenOCD supports three types of JTAG interfaces:
-
-- Parallel port wigglers. These devices connect to a PC's parallel port,
-providing direct access to the JTAG lines. The OpenOCD contains descriptions
-of a few Wiggler layouts, including the original 'Wiggler' design. Other
-layouts (i.e. mapping of parallel port pins to JTAG lines) can be added easily.
-Typical Wiggler speeds are around 12kByte/s code download to an ARM7's RAM.
-
-- The Amontec JTAG Accelerator. This is a configuration for Amontec's Chameleon
-dongle, a parallel port interface based on a Xilinx CoolRunner CPLD. It uses
-the IEEE1284 EPP parallel port specification, providing many times the
-performance achievable with wiggler-style devices. Additional information is
-available on www.amontec.com.
-Typical JTAG Accelerator speeds are around 120-160kByte/s to an ARM7's RAM.
-
-- FTDI FT2232 based USB devices. The FT2232 (but not FT232 or FT245) features a
-multi-protocol synchronous serial engine (MPSSE) that can be used to run the
-serial JTAG protocol. There are several implemenations of FT2232 based devices:
-
-* USBJTAG: http://www.fh-augsburg.de/~hhoegl/proj/usbjtag/usbjtag.html
-The USBJTAG was designed by Prof. Hubert Hoegl to provide a high-speed USB
-interface for use with the OpenOCD. Schematics are available at the USBJTAG
-website, and a homebrew device can easily be built using the FTDI evaluation
-module DLP2232M.
-
-* OOCD-Link: http://www.joernonline.de/dw/doku.php?id=en:projects:oocdlink
-Similar to the USBJTAG, this design comes with free schematics, too.
-
-* Amontec JTAGkey: www.amontec.com
-The Amontec JTAGkey offers support for a wide variety of target voltages from
-1.4V to 5V. It also allows the JTAG lines and reset signals to be tri-stated,
-allowing easy interfacing with a wide variety of targets.
-
-* Amontec JTAGkey-Tiny: www.amontec.com
-The Amontec JTAGkey offers support for a wide variety of target voltages from
-2.8V to 5V. It also allows the reset signals to be tri-stated, allowing easy
-interfacing with a wide variety of targets.
-
-* Olimex ARM-USB-OCD: www.olimex.com
-The Olimex ARM-USB-OCD offers support for a wide vriety of target voltages from
-2.0V to 5V. It also allows targets to be powered from the ARM-USB-OCD and
-features and additional RS232 UART.
-
-* eVerve Signalyzer: www.signalyzer.com
-The Signalyzer offers support for a wide variety of target voltages from 1.2V to
-5.5V. A second connector provides access to a TTL level UART.
-
-All FT2232 based devices may be accessed using either FTDI's proprietary FTD2XX
-library (www.ftdichip.com) or using an open-source replacement from
-http://www.intra2net.com/de/produkte/opensource/ftdi/index.php, also included
-with many Linux distributions.
-
-2. Supported cores
-
-This version of openocd supports the following ARM7/9 cores:
-
-- ARM7TDMI(-s)
-- ARM9TDMI
-- ARM920t
-- ARM922t
-- ARM926ej-s
-- ARM966e
-
-Support for Intel XScale CPUs is also included:
-
-- PXA25x
-- IXP42x
-
-PXA27x debugging should be similar to the PXA25x but fails in the current
-version of OpenOCD.
-
-3. Host platforms
-
-OpenOCD was originally developed on x86-Linux, but has since then been ported
-to run on Windows/Cygwin, native Windows with MinGW, FreeBSD, x86-64-Linux and
-PowerPC OS-X.
-
-4. Documentation
-
-Documentation for the OpenOCD is hosted in the Berlios OpenFacts Wiki at
-http://openfacts.berlios.de/index-en.phtml?title=Open_On-Chip_Debugger.
