    You may receive this error when performing a JTAG operation such as programming, if the Altera JTAG server is not started. Open the Services Control Panel (for example, from the Start menu, point to Settings, then open the Control Panel, select Administrative Tools, and click on Services).

    Look for the Altera JTAG server entry in the list. If the status column is not populated, then right-click Altera JTAG server and choose Start. When the Status of the Altera JTAG Server is set to Started, restart your machine.

    This is not a good solution. Restarting the pc everytime the jtag server is unavailable.

    the jtag server is gone very often. it is not as stable as it was before quartus v.61 we have couple of licence and on every computer the jtag server still dies unexpectedly.

    in other words it is still not posssibel to catch a "strange bug" with signal tap as the jtag sever dies. what we need to do ist to shut down quartus and restart quartus.

    my support told us to completly setup those computers from scratch. done that but nothing changes still having a dying jtag server. even with quartus V7.0 this problem exists.

    great to hear that we are not alone with that, but hopefully there is fix for this available shortly.

    could it be that one of those microsoft updates has changed something that kills the service ?

    btw ... the jtag server is started under the service options.

    I've seen this same problem many times, and it's always been related to one of two things...

    1. Firewall installed on local machine that is not allowing the jtagserver to run. Check to see if you have a firewall running (Norton, McAfee, Windows Firewall, etc). Disable the firewall and this might fix it.

    2. FlexLM version incompatibility.

    Sounds like you used to have things working just fine and now you don't, which means# 2 is not likely the problem. Check your firewall...

    You can run this command line to start the JTAG server:

    jtagserver --start

    To check the status of your JTAG server, run the following command line:

    jtagserver --status

    Thanks, Thanks, Thanks. Using cy2 starter board with win7 with usb blaster driver from Quartus II 9.1 directory. Turned off McAfee's firewall and all started working. :)
