Power Measurement

Hi,

While checking the Jetson Power GUI for power measurement, we could see 3 different Power rating under Power Monitor Tab.

  1. Is VDD_IN is the some of all the Powers? (Including VDD_CPU_GPU & VDD_SOC).
  2. Or we should take these as individual Power and add the total?

Looking forward to your response.

And also, I have mentioned below my observations during CPU GPU Stress Test on the ORIN NX Power Modes.

  1. There is MAXN Super in which the SOM takes ~60W Totally (on a CPU GPU Stress test), the GPU starts to throttle and Power decreases to 40W.
  2. If I change the Mode to 40W, the SOM takes around 50W total.
  3. If Change the Mode to 25W, the SOM power reduces to 25W.
  4. If i reduce further to 15W, the system asks for a reset.

So my qns are,
i) Do we don’t need to restart the device everytime while changing Power modes? Since only when <15W is changed, the restart warning appears on screen.
ii) Why the SOM takes ~50W even though the SOM is limited to 40W mode (during a CPU GPU Stress Test).
