About PWM value of Fan Control

I would like to confirm pwm value of fan cotrol.

In Orin NX, the minimum pwm value of “quiet” mode is 187/255 according to the Fan Profile Control section of software development documentation (r35.2.1)

On the other hand, referring to Jetson_Orin_NX_Series_Orin_Nano_Series_Thermal_Design_Guide_TDG-11127-001_v1.1.pdf document, the minimum pwm value of “quiet” mode is 130/255.
In addition, the PWM value is changing on STEP

which is the correct value during actual operation?
I plan to use Jetpack 5.1 or later.

Since software development documentation (r35.2.1) is new, I’m guessing that the minimum value of pwm value is 187/255

Best regards.

Could you answer my question?

Nvidia doesn’t provide support for NVML. This isn’t even NVML related to begin with. You aren’t going to get an answer here.

Your topic was posted in the wrong category. I am moving this to the Jetson Orin NX category for visibility.

Hi, please follow above sw doc. The TDG will be corrected in new release in future, thanks.

Thank you for your reply.
I Understand.
