-The debugger uses an IEEE 1149-1 compliant JTAG TAP bus master to access on-chip\r
-debug functionality available on ARM7 and ARM9 based microcontrollers /\r
-system-on-chip solutions.\r
-\r
-User interaction is realized through a telnet command line interface and a gdb\r
-(The GNU Debugger) remote protocol server.\r
-\r
-1. JTAG hardware\r
-\r
-Currently, OpenOCD supports the following JTAG interfaces:\r
-\r
-- Parallel port wigglers. These devices connect to a PC's parallel port,\r
-providing direct access to the JTAG lines. The OpenOCD contains descriptions\r
-of a few Wiggler layouts, including the original 'Wiggler' design. Other\r
-layouts (i.e. mapping of parallel port pins to JTAG lines) can be added easily.\r
-Typical Wiggler speeds are around 12kByte/s code download to an ARM7's RAM.\r
-\r
-The list of supported parallel port devices includes:\r
-\r
- * Macraigor Wiggler JTAG cable\r
- * Gateworks GW16012 JTAG programmer\r
- * Xilinx DLC5 JTAG parallel cable III\r
- * Ka-Ro TRITON starterkit II JTAG cable\r
- * Lattice parallel port JTAG cable\r
- * ST FlashLINK programming cable\r

-- The Amontec JTAG Accelerator. This is a configuration for Amontec's Chameleon\r
-dongle, a parallel port interface based on a Xilinx CoolRunner CPLD. It uses\r
-the IEEE1284 EPP parallel port specification, providing many times the\r
-performance achievable with wiggler-style devices. Additional information is\r
-available on www.amontec.com.\r
-Typical JTAG Accelerator speeds are around 120-160kByte/s to an ARM7's RAM.\r
-\r
-- FTDI FT2232 based USB devices. The FT2232 (but not FT232 or FT245) features a\r
-multi-protocol synchronous serial engine (MPSSE) that can be used to run the\r
-serial JTAG protocol. There are several implemenations of FT2232 based devices:\r
-\r
-* USBJTAG: http://www.fh-augsburg.de/~hhoegl/proj/usbjtag/usbjtag.html\r
-The USBJTAG was designed by Prof. Hubert Hoegl to provide a high-speed USB\r
-interface for use with the OpenOCD. Schematics are available at the USBJTAG\r
-website, and a homebrew device can easily be built using the FTDI evaluation\r
-module DLP2232M.\r
-\r
-* OOCD-Link: http://www.joernonline.de/dw/doku.php?id=en:projects:oocdlink\r
-Similar to the USBJTAG, this design comes with free schematics, too.\r
-\r
-* Amontec JTAGkey: www.amontec.com\r
-The Amontec JTAGkey offers support for a wide variety of target voltages from\r
-1.4V to 5V. It also allows the JTAG lines and reset signals to be tri-stated,\r
-allowing easy interfacing with a wide variety of targets.\r
-\r
-* Amontec JTAGkey-Tiny: www.amontec.com\r
-The Amontec JTAGkey offers support for a wide variety of target voltages from\r
-2.8V to 5V. It also allows the reset signals to be tri-stated, allowing easy\r
-interfacing with a wide variety of targets.\r
-\r
-* Olimex ARM-USB-OCD: www.olimex.com\r
-The Olimex ARM-USB-OCD offers support for a wide vriety of target voltages from\r
-2.0V to 5V. It also allows targets to be powered from the ARM-USB-OCD and\r
-features and additional RS232 UART.\r
-\r
-* eVerve Signalyzer: www.signalyzer.com\r
-The Signalyzer offers support for a wide variety of target voltages from 1.2V to\r
-5.5V. A second connector provides access to a TTL level UART.\r
-\r
-* TinCanTools 'Flyswatter' USB JTAG programmer.\r
-\r
-* Turtelizer 2: http://www.ethernut.de/en/hardware/turtelizer/index.html\r
-Another USB JTAG programmer, with freely available schematics. It supports\r
-target voltages from 1.65V to 5.5V.\r
-\r
-* Hitex STR9-comSTICK: http://www.ehitex.de/p_info.php?products_id=292\r
-A STR912FW44x microcontroller "board" with USB and JTAG functionality.\r
-\r
-* Luminary Micro development board evb_lm3s811 JTAG interface.\r
-\r
-* ASIX PRESTO: http://www.asix-tools.com/prg_presto.htm\r
-The ASIX PRESTO is a USB JTAG programmer for a wide range of components, e.g.\r
-microcontrollers, serial EEPROM and Flash memory chips, CPLDs and others.\r
-\r
-* usbprog: http://www.embedded-projects.net/index.php?page_id=165\r
-The usbprog is a freely programmable USB adapter, which can (among other\r
-things) use a firmware which turns it into a JTAG programmer/debugger.\r
-\r
-All FT2232 based devices may be accessed using either FTDI's proprietary FTD2XX\r
-library (www.ftdichip.com) or using an open-source replacement from\r
-http://www.intra2net.com/de/produkte/opensource/ftdi/index.php, also included\r
-with many Linux distributions.\r
-\r
-2. Supported cores\r
-\r
-This version of openocd supports the following ARM7/9 cores:\r
-\r
-- ARM7TDMI(-s)\r
-- ARM9TDMI\r
-- ARM920t\r
-- ARM922t\r

-\r
-And support for the Marvell Feroceon CPU core as found in the\r
-Orion SOC family is included as well.\r
-\r
-3. Host platforms\r
-\r
-OpenOCD was originally developed on x86-Linux, but has since then been ported\r
-to run on Windows/Cygwin, native Windows with MinGW, FreeBSD, IA64-Linux,\r
-AMD64-Linux, Alpha-Linux, ARM-Linux, and PowerPC OS-X.\r
-\r
