User interaction is realized through a telnet command line interface and a gdb
|
||||
(The GNU Debugger) remote protocol server.
|
||||
|
||||
Initially, support for two JTAG TAP bus master interfaces with public hardware
|
||||
schematics will be included, but support of additional hardware is an expressed
|
||||
goal.
|
||||
|
||||
1. JTAG hardware
|
||||
|
||||
Currently, openocd contains support for Wiggler-compatible paralell port
|
||||
dongles and a USB interface based on the FTDI FT2232, called USBJTAG-1.
|
||||
A new version of the USB interface, USB-JTAG v1.2, is available with complete
|
||||
schematics (http://www.fh-augsburg.de/~hhoegl/proj/volksmikro/usb-jtag/050910/).
|
||||
Currently, OpenOCD supports three types of JTAG interfaces:
|
||||
|
||||
It was tested using Amontec's (www.amontec.com) Chameleon POD in it's
|
||||
Wiggler configuration, but homemade wigglers should work just as well.
|
||||
In order to use the reset functionality (warm-reset, debug from reset, reset
|
||||
and init), the choosen Wiggler has to connect the nSRST line.
|
||||
- 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.
|
||||
|
||||
USBJTAG-1 is based on a FTDI DLP2232M module and a few additional parts.
|
||||
Schematics are freely available. USB-JTAG v1.2 doesn't use the DLP2232M, but
|
||||
has the FTDI chip soldered directly on the PCB. There are two drivers for these
|
||||
modules implemented, one using the open source libftdi, the other using FTDI's
|
||||
proprietary FTD2XX library.
|
||||
- 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.
|
||||
|
||||
* 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.
|
||||
|
||||
* 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 cores:
|
||||
|
||||
- ARM7TDMI
|
||||
- ARM7TDMI(-s)
|
||||
- ARM9TDMI
|
||||
- ARM920t
|
||||
- ARM922t
|
||||
- ARM966e
|
||||
|
||||
Support for cores with MMUs (ARM720t, ARM920t) is currently being merged.
|
||||
Support for Intel XScale CPUs (PXA25x, PXA27x and IXP4xx) is currently being
|
||||
developed.
|
||||
|
||||
3. Licensing
|
||||
The OpenOCD is only tested with little-endian targets, but support for
|
||||
big-endian is planned. If you're interested in helping with this (and you
|
||||
happen to have a big-endian ARM7/ARM9 system, feel free to contact
|
||||
Dominic.Rath <at> gmx.de.

||||

||||

||||
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
|
||||
(though it's not fully working yet) 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.

||||

||||
