Jetson Clocks have default value "running"

I’m using the Orin Nano. According to this post, it seems that ‘jetson clocks’ should not be ‘running’ at boot time. However, when I use jtop, I find that its default state at boot is ‘running’. I would like to know how to enable the DVFS governor.

Could you check with tegrastats?

Here is the tegrastas output:

jetson@unbutu:~$  sudo nvpmodel -q

What is the jetpack version you are using?

Version: 5.1.1-b56

I wonder if this is because the seller made some settings before I purchased the device? Is it possible to switch back to DVFS mode through a command?

Jetson clocks should not run by default as you said. Your situation is abnormal.

Is it a custom board or NV devkit?

It is an NV devkit. But I’m using the SSD provided by the seller along with the OS they supplied.

I guess they enabled jetson clocks by default.

Thank you, Wayne. I will seek help from the seller.

I have another question I’d like to inquire about:
I am writing a script to capture the power consumption of the device, hoping to output the device’s VDD_IN/VDD_CPU_GPU_CV/VDD_SOC by usingsudo tegrastats. The script works well on the Orin Nano.
But the output of sudo tegrastats on the AGX Xavier (for the power consumption part) is:

GPU 0mW/0mW CPU 456mW/456mW SOC 1064mW/1064mW CV 0mW/0mW VDDRQ 152mW/152mW SYS5V 1650mW/1650mW

It seems I cannot directly obtain the values of VDD_CPU_GPU_CV/VDD_IN like on the Orin Nano. I wonder if these can be calculated? For example, can VDD_CPU_GPU_CV be calculated by adding GPU+CPU+CV? Can VDD_IN be calculated by adding CPU+GPU+SOC+VDDRQ+SYS5V?

Once again, thanks for your help.

You could refer to this document for detail.
