I have similar problem too. My on-board JTAG doesn't work anymore after working for several months. I have cyclone II

i found the tck net is about 35 ohms to gnd. In both directions.

When power is supplied, I get 3.28V on TCK pin, I didn't notice over comsumption.

I can still configure with Active Serial Programming. I notice that I have no progress bar but programming is succesfull.

But I can't programm flash by Nios II.
