I am responding to very old thread but I think this may be useful to somebody as we also faced same issue. It looks noise as one possible reason for this. You may like to check is there anything which could create noise on JTAG related lines. It might also be worth to have a look at https://www.altera.com/support/support-resources/knowledge-base/solutions/rd06292006_529.html (https://www.altera.com/support/support-resources/knowledge-base/solutions/rd06292006_529.html) Similar threads which may also be helpful: https://www.alteraforum.com/forum/showthread.php?t=27179 http://alterauserforums.com/forum/showthread.php?t=14747 Regards, Bhaumik
