Hello,
I am trying to manage the pin map of TX2 to enable a PWM pin by referring to the below link.
https://docs.nvidia.com/jetson/l4t/index.html#page/Tegra%20Linux%20Driver%20Package%20Development%20Guide/hw_setup_jetson_io.html
However, when I run “sudo /opt/nvidia/jetson-io/jetson-io.py,” the outcome quickly disappears and so cannot proceed further (The solution shown in the Note does not help to solve the issue).
I am using a Jetson TX2 with an Orbitty carrier board.
Is there anyone who configure this problem?

Never mind. It turns out the TX2 does not support any physical PWM channel.
[Summary of Jetson Series Physical PWM Support]
Jetson Nano: 2 PWM channels (#32 , #33 )
Jetson AGX Xavier: 3 PWM channels (#13 , #15 , #18 )
Jetson Xavier NX: 2 PWM channels (#32 , #33 )
Jetson TX1 and TX2: Do not support any PWM channels
