Although the thread is rather old, but this problem exists with some of Altera's product. The driver you need is in Altera's Driver folder.
You have to install the driver manually for the board.ĭon't let windows install it for you. If that doesn't work, I've also had success using the Windows Reinstall Driver function. Close the programmer and power cycle the board. I reinstalled and ran the program this time with admin privileges and antivirus turned off and then it worked.
Why can't it work? From the command-line I can run a tool named jtagconfig that actually seems to find the board but this is from the command line. I reinstalled the drivers, reinstalled Quartus II different versions many times, reset the board, tried both the Quartus version from the CD and from the internet, I see many other people have the same problem with the same board, thank you Altera for making us lose valuable time wasting our time on faulty software. But when I start Quartus Programmer to download my logic to the board, the hardware part of the interface is blank where I expect to see my card: What can be done? The instructions I have are available here.
And the card appears in the device manager so it indeed looks correct so far. I use Quartus II web edition and using that driver my computer can find the card.
