Jetson Xavier NX: System throttled due to Over-current

[violator86]

Hello
While the detectors (deepstream-emotion/gaze-app) are running, I get the system notification “System throttled due to Over-current” - warnings in online and offline mode - processing of the video stream from the webcam, and video files, respectively.
Judging by the graphs, the reason is the lack of current (see attached images).

I have several questions:

1. Is it possible to ignore these warnings (wouldn’t it be harmful to ignore these warnings)?
2. can the use of a more powerful power supply lead to damage to the power circuit in particular, or to the entire Jetson as a whole?
3. what can be fraught with software removal of the current consumption limit (yes, I have seen similar topics on the forum, however, this question causes the greatest concern)?

The used power supply is standard from the delivery set: voltage 19V, current 2.37A (see attached images).

Hardware:
Jetson Xavier NX

please check

The error message "System throttling due to over-current" appears when running YOLOv4

Need to make some clarifications for this issue. The OC throttling case also appears in jetpack4.4.1. The real cause that makes you feel this issue does not happen on jp4.4.1 is because there was no “OC alarm notification” mechanism implemented in jp4.4.1. Thus, jp4.5 and jp4.4.1 actually both have oc throtting. The oc throtting is due the the hardware limitation of NX module. We currently set OC limit to 3.6A to protect the NX hardware. The suggestion to prevent the OC throtting not…

System throttled due to over-current?

hi all, could you please have the workaround to increase instantaneous OC limit, from 3.6A to 5A; this 5A workaround should still acceptable with hardware aspect. please have below command to set 5A instantaneous OC limit: for example, # echo 5000 > /sys/devices/c250000.i2c/i2c-7/7-0040/iio:device0/crit_current_limit_0 looking forward your feedbacks whether this approach works or not. thanks!

Hello
Unfortunately, the command does not work, a message is displayed stating that the directory is not available:

professorx@ubuntu:~$ sudo echo 5000 > /sys/devices/c250000.i2c/i2c-7/7-0040/iio:device0/crit_current_limit_0
bash: /sys/devices/c250000.i2c/i2c-7/7-0040/iio:device0/crit_current_limit_0: No such file or directory
professorx@ubuntu:~$

p.s. I also found mentions that this command does not work for another user on JP5.1, as well as a mention of your colleague about the maximum current of 5A on JP5.1:

Thank You! I just want to confirm one thing. I saw this solution for jetpack 4.5, will this work for jetpack 5.1? # echo 5000 > /sys/devices/c250000.i2c/i2c-7/7-0040/iio:device0/crit_current_limit_0 Although I did check that c250000 folder is not present in devices. Thanks

Hi, The command rise the OC limit to 5A. But the default setting in JetPack 5.1 is already 5A. We are checking this issue internally. Will share more information with you later. Thanks

Hi,

If you are on rel-35, then you don’t need to apply this command. The rel-35 already uses 5A by default.

@WayneWWW

rel-35

Can you please elaborate?

[WayneWWW]

Not sure what to elaborate here.

JP4 is using rel-32 branch. JP5 is using rel-35 branch. All jp5 release already set the OC limit of XNX to 5A.
It is okay that you cannot find that node to configure because there is no need to configure it at all.
