What is the correct voltage/signal/shape on the charge pump capacitors? Should it be constant or some type of wave form?
When the capacitors are connected you will not be able to observe these because once the capacitors are charged the voltage will be kept at a steady level.
Have you measured these with the capacitors connected ?
The images with the saw tooth pulses are normal for a capacitor as it charges/discharges, I guess depending on the load and the size of the capacitor the amplitude can change.
The other images with the narrow sharp edges look strange but I don't know if they should be like that or not, especially in your first image the rate of these narrow edges is not periodic.
