I figure I should finally ask about this problem that I've had with every Quartus version I've used (since pre-4.2): The built-in programmer in Quartus stops working after a few sessions -- always. Typically I get one or two successful programming done (using a Nios Dev kit, Cyclone ed) before it fails with:
Info: Started Programmer operation at Mon Jul 11 20:54:11 2005 Error: Unexpected error in JTAG server -- error code 33 Error: Operation failed Info: Ended Programmer operation at Mon Jul 11 20:54:11 2005
At this point any attempt at programming is futile and will just repeat the error above. However, closing the programmer window/tab and relaunching Tools/Programmer makes it work again for a bit. It's really kind of annoying, but googling for a solution to the problem didn't turn up anything.
While we're at it, why isn't the programmer integrated into the build instead of forcing a manual invokation?
