Hi，
I tried to practice the pwm capture sample in frdm_mcxw72 board, but unfortunately, the print message in serial tool only show " capture cycle err -134" . I'm sure there is the 1Khz, 50% duty cycle pwm signal inject into the PTA21 pins in frdm_mcxw72 board.
i imported the whole project files from the demo case, there is no change that i only added the overlay file, below is the overlay files setting.
can you help check the reason why there is no correct print information. thanks in advance!
