AGX Orin PWM pins output power?

I am using agx orin dev kit 64 gb for a project, I need to use trigger signals to drive my camera. Earlier I was using just the GPIO pins on the jetson for those triggers, but the drift is high. So, I tried to shift to PWM signals. I enabled PWM on pin 15 and 18 and tried everything. Including the simple_pwm.py code on jetson.gpio, It ran without any error but my camera didnt turn on using PWM triggers. Is there any voltage/power limit to these PWM pins and if so can we change them?

camera: The imaging source DMK37BUX273 and DMK287BUX.

hello chaudharyyash2004,

please see-also Topic 272030 for reference,
BTW, is it possible to probe the hardware to check it’s actually toggling the pin?

@JerryChang thank you for your reply, we checked by oscilloscope that PWM is giving output but PWM pins are all in pull down configuration which is not able to drive the cameras. So, we are searching for additional hardware to increase output current/voltage.
