My customer tried to generate some PWM outputs working on the i.MX RT1050. But the PWM waveform accuracy is not correct. I reproduced this issue with i.MX RT1050 EVKB, using demo code $\boards\evkbimxrt1050\driver_examples\qtmr\inputcapture_outputpwm in SDK. It should probe a 50Khz PWM signal output with 50% dutycycle. The oscilloscope shows the PWM output at pin J23-5 accuracy was about 49.7K.
