I want to use PWM. jetson-io.py doesn’t seem to be working. To be precise, when I type sudo /opt/nvidia/jetson-io/jetson-io.py, it seems to turn on for 0.1 seconds and then turn off. No error message appears. My English is not good, but it is possible to read. Please help me…

Hi carrotman,

Are you using the devkit or custom board for Jetson Nano?
What’s your Jetpack version in use?

Could you share the result of the following command on your board?

$ ls -l /boot
