The w11 project uses the open source JTAG Access software from the
SourceForge project
urjtag
for configuring FPGA over the Cypress FX2 USB Interface available on Digilent
Nexys2, Nexys3 and Atlys boards.
The most recent version works fine. This version is delivered with
Ubuntu 12.04 LTS and later Ubuntu versions. In this case simply install the
package 'urjtag'. Try the command
jtag
it should print
UrJTAG 0.10 #2007
and show a version number of '#2007' or higher.
Old versions unfortunately have a string size limitation problem with can
lead to problems when used with Digilent S3BOARDS (or other cases with
multiple devices in the jtag chain). Therefore for
Debian Squeeze and older
Ubuntu 11.10 (oneiric) and older
or if the 'jtag' command prints something like
UrJTAG 0.10 #1502
UrJTAG 0.9 #1476
it is advisible to install the urjtag software from sources.
Simlest is to install an up-to-date version directly from the SourceForge
svn repository, start at
http://sourceforge.net/scm/?type=svn&group_id=193266&source=navbar
do a 'svn co' for revision 2007 or later, build and install.
Alternatively start with the V0.10 (rev #1502) tarball available from
http://sourceforge.net/projects/urjtag/files/?source=navbar
and download
urjtag-0.10.tar.gz (dated 2009-04-17)
Change in file src/cmd/parse.c the line
#define MAXINPUTLINE 100 /* Maximum input line length */
and replace '100' with '512', build and install.
