+@section Pre-Built Tools
If you are interested in getting actual work done rather than building
OpenOCD, then check if your interface supplier provides binaries for
you. Chances are that that binary is from some SVN version that is more
stable than SVN trunk where bleeding edge development takes place.

You can download the current SVN version with SVN client of your choice from the
following repositories:

In general, the D2XX driver provides superior performance (several times as fast),
but has the draw-back of being binary-only - though that isn't that bad, as it isn't

+@option{--enable-ft2232_ftd2xx} - Numerous USB Type ARM JTAG dongles use the FT2232C chip from this FTDICHIP.COM chip (closed source).
@item

+@item
+@option{--with-ftd2xx-lib=shared|static} - Linux only. Default: static, specifies how the FTDICHIP.COM libftd2xx driver should be linked. Note 'static' only works in conjunction with @option{--with-ftd2xx-linux-tardir}. Shared is supported (12/26/2008), however you must manually install the required header files and shared libraries in an appropriate place. This uses ``libusb'' internally.

+@section Parallel Port Dongles
+
If you want to access the parallel port using the PPDEV interface you have to specify
both the @option{--enable-parport} AND the @option{--enable-parport_ppdev} option since
the @option{--enable-parport_ppdev} option actually is an option to the parport driver
(see @uref{http://forum.sparkfun.com/viewtopic.php?t=3795} for more info).
-Cygwin users have to specify the location of the FTDI D2XX package. This should be an
-absolute path containing no spaces.
+@section FT2232C Based USB Dongles
+
+There are 2 methods of using the FTD2232, either (1) using the
+FTDICHIP.COM closed source driver, or (2) the open (and free) driver
+libftdi. Some claim the (closed) FTDICHIP.COM solution is faster.
-Linux users should copy the various parts of the D2XX package to the appropriate
-locations, i.e. /usr/include, /usr/lib.
+The FTDICHIP drivers come as either a (win32) ZIP file, or a (linux)
+TAR.GZ file. You must unpack them ``some where'' convient. As of this
+writing (12/26/2008) FTDICHIP does not supply means to install these
+files ``in an appropriate place'' As a result, there are two
+``./configure'' options that help.
-Miscellaneous configure options
+Below is an example build process:
+
+1) Check out the latest version of ``openocd'' from SVN.
+
+2) Download & Unpack either the Windows or Linux FTD2xx Drivers
+ (@uref{http://www.ftdichip.com/Drivers/D2XX.htm})
+
+@example
+ /home/duane/ftd2xx.win32 => the Cygwin/Win32 ZIP file contents.
+ /home/duane/libftd2xx0.4.16 => the Linux TAR file contents.
+@end example
+
+3) Configure with these options:
+
+@example
+Cygwin FTCICHIP solution
+ ./configure --prefix=/home/duane/mytools \
+ --enable-ft2232_ftd2xx \
+ --with-ftd2xx-win32-zipdir=/home/duane/ftd2xx.win32
+
+Linux FTDICHIP solution
+ ./configure --prefix=/home/duane/mytools \
+ --enable-ft2232_ftd2xx \
+ --with-ft2xx-linux-tardir=/home/duane/libftd2xx0.4.16
+
+Cygwin/Linux LIBFTDI solution
+ Assumes:
+ 1a) For Windows: The windows port of LIBUSB is in place.
+ 1b) For Linux: libusb has been built and is inplace.
+
+ 2) And libftdi has been built and installed
+ Note: libftdi - relies upon libusb.
+
+ ./configure --prefix=/home/duane/mytools \
+ --enable-ft2232_libftdi
+
+@end example
+
+4) Then just type ``make'', and perhaps ``make install''.
