I tried to use pwm using jetson io pin.
But it didn’t work at all.
I used an oscilloscope, but I didn’t see any output of the signal.
What I know is that when I install Jetpack, Jetson.GPIO is installed by default.
(After installing jetpack, I checked it using the Python interpreter.)
After activating pwm through jetson-io.py and rebooting, I ran a simple sample example, but only GND and power pins worked, but no signal came out.
I ran the same code on the same equipment, but the pin doesn’t work, so I’m going crazy. (It’s been 2 weeks already)
A brief summary of my attempts
Activate pin 13 that supports pwm through jetson-io.py (rebooted of course).
A simple code was executed.
However, no signal was detected and many similar samples were searched, but to no avail.
Then, I installed the jetpack again, and installed it again and again endlessly.
But it doesn’t work and it’s just sad.
I’m not sure if this is a hardware failure or if my gpio configuration is wrong.
The other agx xavier I have is working fine, but only this one doesn’t work.

Description: NVIDIA Jetpack Meta Package
Also added example code :
import Jetson.GPIO as GPIO
pwm = GPIO.PWM(SERVO_PIN, 1000)
for t_high in range(30, 1000):
a=int(input("pwm here : "))
In addition, it seems that jetson.gpio is not installed in the relevant xavier, so I installed Jetson.gpio arbitrarily after installing jetpack.
Is this the cause of the problem?
