gdb-server can't find Cyclone II board

I'm trying to connect to a Cyclone II board using jtagd and nios2-gdb-server-wrapped under Linux.

They seem to find the USBBlaster OK -- the blue LED flashes briefly when I start the gdb-server, but then the gdb-server complains and exits: 

# ./nios2-gdb-server-wrapped
There are no Nios II CPUs with debug modules available which match the values
specified.  Please check that your PLD is correctly configured, downloading a
new SOF file if necessary.#

Questions:[list][*]In the message above to what does the phrase "the values specified" refer? I don't see where I specified any values.[*]What command line parameters or config file entries do I need to connect to a Cyclone II demo board? I don't have a .jtag.conf file, and I know the gdb-server tries to read ~/.jtag.conf. Neither did I specify a config file when I started jtagd.

    would you please add a page on nios wiki to describe how to setup the gdb server?

    that would be very helpful. http://forum.niosforum.com/work2/style_emoticons/<#emo_dir#>/smile.gif

    Done: http://nioswiki.jot.com/wikihome/linuxgdbserver (http://nioswiki.jot.com/wikihome/linuxgdbserver)

    I see that we&#39;re encouranged to "sign our work" on the Wiki, but I&#39;ve no clue what that means or how to do it.

    FWIW, my privilege problem was due to the fact that I forgot to make /etc/hotplug/usb/usbblaster executable. Making jtagd suid root didn&#39;t work because suid executables ignore the LD_LIBRARY_PATH environment variable.

    Thanks. It looks great.

    I don&#39;t understand what they mean by "sign your work", too.
