I'm having a weird problem with a Teensy 3.5 I recently purchased. Pin 15 only reads when I press on the top of the CPU chip. It (and about 40 other pins I'm reading from) are pulled up to 5v with 18k resistor packs. All of the other pins read as expected (normally high, read low when grounded).
Pin 15, however, seems to stay stuck in whatever state it was last in unless I press down on the top half of the CPU. Removing pressure from the CPU seems to leave it stuck in the last read state. All the other pins seem to read fine.
Is it possible the CPU has a bad solder joint to the board? It's only about 2 months old, been sitting on my bench until my boards from OSHPark arrived last week...
