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.
