Installing OpenOCD
==================
+On Linux, you may have permissions problems to address. The best
+way to do this is to use the contrib/udev.rules file. It probably
+belongs somewhere in /etc/udev/rules.d, but consult your operating
+system documentation to be sure. In particular, make sure that it
+matches the syntax used by your operating system's version of udev.

A Note to OpenOCD Users
-----------------------
The INSTALL file contains generic instructions for running 'configure'
and compiling the OpenOCD source code. That file is provided by default
for all GNU automake packages. If you are not familiar with the GNU
-autotools, then you should read those instructions first.

The remainder of this document tries to provide some instructions for
those looking for a quick-install.

The 'configure' step generates the Makefiles required to build OpenOCD,
cross-compile on a x86 Linux host to run on Windows (MinGW32), you could
use the following configuration options:
- ./configure --build=i686-pc-linux-gnu --host=i586-mingw32msvc ...
+ ./configure --build=i686-pc-linux-gnu --host=i586-mingw32msvc ...
Likewise, the following options allow OpenOCD to be cross-compiled for
an ARM target on the same x86 host:

--enable-ft2232_ftd2xx Enable building support for FT2232 based devices
using the FTD2XX driver from ftdichip.com
- --enable-ftd2xx-highspeed
- Enable building support for FT2232H and

--enable-gw16012 Enable building support for the Gateworks GW16012

Using LIBFTDI
-------------
+The libftdi source code can be download from the following website:

For both Linux and Windows, both libusb and libftdi must be built and
installed. To use the newer FT2232H chips, supporting RTCK and USB high
speed (480 Mbps), you need libftdi version 0.16 or newer. Many Linux
distributions provide suitable packages for these libraries.
-For Windows, libftdi is supported with versions 0.14 and later.

it to non-redistributable OpenOCD binaries, and it is not available for

If your distribution does not package these, there are several

Remember, this library is binary-only, while OpenOCD is licenced
according to GNU GPLv2 without any exceptions. That means that

+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.
