OpenOCD provides on-chip programming and debugging support with a
layered architecture of JTAG interface and TAP support including:
-- (X)SVF playback to faciliate automated boundary scan and FPGA/CPLD
+- (X)SVF playback to facilitate automated boundary scan and FPGA/CPLD
programming;
- debug target support (e.g. ARM, MIPS): single-stepping,
breakpoints/watchpoints, gprof profiling, etc;
openocd -f interface/ftdi/jtagkey2.cfg -c "transport select jtag" \
-f target/ti_calypso.cfg
- openocd -f interface/stlink-v2-1.cfg -c "transport select hla_swd" \
+ openocd -f interface/stlink.cfg -c "transport select hla_swd" \
-f target/stm32l0.cfg
-NB: when using an FTDI-based adapter you should prefer configs in the
-ftdi directory; the old configs for the ft2232 are deprecated.

==================
particular hardware;
- Use "ftdi" interface adapter driver for the FTDI-based devices.
-As a PACKAGER, never link against the FTD2XX library, as the resulting
-binaries can't be legally distributed, due to the restrictions of the
-GPL.

================
Building OpenOCD
Additionally, for building from git:
- autoconf >= 2.64
-- automake >= 1.9
+- automake >= 1.14
- texinfo
USB-based adapters depend on libusb-1.0 and some older drivers require
libusb-0.1 or libusb-compat-0.1. A compatible implementation, such as
FreeBSD's, additionally needs the corresponding .pc files.
-USB-Blaster, ASIX Presto, OpenJTAG and ft2232 interface adapter
-drivers need either one of:
+USB-Blaster, ASIX Presto and OpenJTAG interface adapter
+drivers need:
- libftdi: http://www.intra2net.com/en/developer/libftdi/index.php
- - ftd2xx: http://www.ftdichip.com/Drivers/D2XX.htm (proprietary,
- GPL-incompatible)
CMSIS-DAP support needs HIDAPI library.
Running OpenOCD with root/administrative permissions is strongly
discouraged for security reasons.
-For USB devices on GNU/Linux you should use the contrib/99-openocd.rules
+For USB devices on GNU/Linux you should use the contrib/60-openocd.rules
file. It probably belongs somewhere in /etc/udev/rules.d, but
consult your operating system documentation to be sure. Do not forget
to add yourself to the "plugdev" group.
To make pkg-config work nicely for cross-compiling, you might need an
additional wrapper script as described at
- http://www.flameeyes.eu/autotools-mythbuster/pkgconfig/cross-compiling.html
+ https://autotools.io/pkgconfig/cross-compiling.html
This is needed to tell pkg-config where to look for the target
libraries that OpenOCD depends on. Alternatively, you can specify
*_CFLAGS and *_LIBS environment variables directly, see "./configure
--help" for the details.
+For a more or less complete script that does all this for you, see
+
+ contrib/cross-build.sh

Parallel Port Dongles
---------------------
If you want to access the parallel port using the PPDEV interface you
-have to specify both --enable-parport AND --enable-parport-ppdev, since the
+have to specify both --enable-parport AND --enable-parport-ppdev, since
the later option is an option to the parport driver.
The same is true for the --enable-parport-giveio option, you have to
if you want to use giveio instead of ioperm parallel port access
method.
-Using FTDI's FTD2XX
--------------------
-
-The (closed source) FTDICHIP.COM solution is faster than libftdi on
-Windows. That is the motivation for supporting it even though its
-licensing restricts it to non-redistributable OpenOCD binaries, and it
-is not available for all operating systems used with OpenOCD. You may,
-however, build such copies for personal use.
-
-The FTDICHIP drivers come as either a (win32) ZIP file, or a (Linux)
-TAR.GZ file. You must unpack them ``some where'' convenient. As of this
-writing FTDICHIP does not supply means to install these files "in an
-appropriate place."
-
-You should use the following ./configure options to make use of
-FTD2XX:
-
- --with-ftd2xx-win32-zipdir
- Where (CYGWIN/MINGW) the zip file from ftdichip.com
- was unpacked <default=search>
- --with-ftd2xx-linux-tardir
- Where (Linux/Unix) the tar file from ftdichip.com
- was unpacked <default=search>
- --with-ftd2xx-lib=(static|shared)
- Use static or shared ftd2xx libs (default is static)
-
-Remember, this library is binary-only, while OpenOCD is licenced
-according to GNU GPLv2 without any exceptions. That means that
-_distributing_ copies of OpenOCD built with the FTDI code would
-violate the OpenOCD licensing terms.
-
-Note that on Linux there is no good reason to use these FTDI binaries;
-they are no faster (on Linux) than libftdi, and cause licensing issues.
