One more time, please, why can't I use all 3 Jetson Nano PWMs for 3 fans?

How I got from this:

All PWMs has their specific firmware that I cannot touch but I must be able to throw all PWMs in /sys and then I’ll be able to rule their manually from this. Or not?
I can read temperature in Linux from I2C and write to /sys for PWMs their value? Again, or not?)

Hi,

If you are talking about using a valid pwm pin from the design guide and let it generate out a node under /sys/ then it could work.

But if you are talking about you want to combine your fan into thermal design, then default jetson thermal driver won’t know the existence of your extra pwm fan.

Okey, so, then I will try to trow PWM into the /sys and rule it over there
