I believe that (pin 53) is all that is necessary for this stuff to work.

The player s/w uses pin 53 to detect AC/DC. So if you see the player thinking "AC" when it's really on "DC" (or the other way round), and pin 53 has been verified to be getting the correct levels, then that input on the SA1100 is probably fried.

Just to recap: is that the actual problem here: player uses DC when on AC (or vice-versa)?

??


Player on DC equals 3.3 volts at pin 53, but player is in AC mode. Player on AC equals 0 volts at pin 53 and player is in AC mode. So you vote for dead GPIO? I was leaning towards that too, I was just hoping there was some other component that might be to blame.

The other problem is that the unit does not boot reliably. Perhaps they are both from a sick Strongarm?
