17 microseconds is 58 KHz. That's a reasonable number for a switching power supply. What does your power look like? I don't know what you are using for a circuit. My guess is that the crap on the power is shifting the switching point slightly. Note that both your scope and your BBB are digital sampling systems so you have opportunities for aliasing. For the scope pictures, you have to consider 3 clocks. The 3rd one is the clock in the scope. My guess is that the fuzzy regions on your digital scope pictures are when the scope samples while the input signal is switching. Do you (or a friend) have an analog scope? It would be fun to set it up in parallel with the digital scope. -- These are my opinions.
