I tried the circuit with a a single pole, double throw switch to both ground and +5 volts with a 47k resistor in line with the +5 volts (as is done in all other cases on the eval board) to the RST pin. It still doesn't want to work, but the interesting thing is that when the RST pin is high, I now get a low level, high pitched digital buzzing noise from my DAC. That may mean I'm getting closer. Any other suggestions? I'll try posting the exact schematic as best I can later. I am going to continue to make adjustments to the jumpers and see if that helps.
