A driver conflict occurs when you connect two digital
outputs together and configure one to drive high and the other to drive low.
The DE0-nano pins can be configured as both inputs and outputs. If you have added some wire to the header so that you can output on one pin, and then read-back the signal on another, then it is quite possible that you have accidentally created a driver conflict.
If you have not added any extra wires to the board, then this is not your problem.
How are you measuring the signal on the pin? With a voltmeter or an oscilloscope?
