Honored ContributorI have posted this to another thread, maybe it is also relevant to this one:
... I seem to have similar problems. I use JTAGTest (http://www.jtagtest.com/) with ViaTAP interface ( http://www.jtagtest.com/viatap ). Program says "no devices detected in JTAG chain" ... and nothing else. For other boards with JTAG parts I have it works fine. I can post my schematics somewhere if needed. I really need to use JTAGTest with Stratix to verify solder joints ... Would anyone confirm that Stratix meets "Design guidelines for use with ViaTAP" in ViaTAP JTAG HW manual at http://www.jtagtest.com/docs ? I did not see anything wrong in Stratix PDF docs. It definitely works fine with Cyclone or Max/MaxII (tested), but this is my first Stratix design... Thank you!
