Other Parts Discussed in Thread: TIDM-1007,
One of my customers encountered an abnormal driver waveform when testing the suite. When the program was running normally, epwm2a would suddenly be set down by one duty, as shown in the following figure:
The software is the original code and has not been modified. The location of the test point is the original test point of the development board, PWM-1 and PWM-2. His colleagues will also encounter this problem when using the code of this development board. He tried to get rid of the peripheral load and supply power to the development board separately. In other words, in the no-load state, he would also see this problem. This abnormal state exists in different voltages and loads.
I would like to know what causes this? Is it possible that the development board has hardware problems?
