I got my jetson nano dev kit, set it up and when using the jetson copilot tutorial, I get the notifications. I am using the power supply that comes with the kit.. Is there anything else I need to do?
Hi,
This is possible when running heavy-loading application. It is protection mechanism to the hardware device. If over current is frequently triggered and you would like to reduce it, you may tune a power mode for running the application. There are several default power modes, you can base on either mode and try to reduce CPU frequency or GPU frequency. So that the engine doesn’t drain too much current.
I will add that the message does not differentiate between a maxed out system which is actually overheating, and one which is in some low power mode and trying to avoid going outside of that low power limit which the end user has set. If the Jetson is using some tiny power mode, e.g., 10W, and the system wants to use 12W, then it will throttle and give that message. If the unit has some “super duper” mode, e.g., 150W (no, they don’t really have that, it’s just a contrived example), and it is about to fry all the circuitry and melt the solder off, then it would be the same message. The only time this is actually protecting against a failure is if the power mode is the max and higher power would cause damage and/or instability.
Thank you, I had selected even the MAX mode and it was giving me the same notification. The power monitor was telling me that the current was well within the limits.. around 900 mA if I recall correctly…
I don’t know the details of the MAX mode, but there is a possibility that current in different subcomponents might max prior to current draw as a whole maxes out. Or, there could be an actual temperature limit being reached (again, this might be a high temp on one sensor despite other locations being cool enough). If the ambient temperature is cooled, e.g., you put additional fans on this temporarily, then you could experiment with how easy this is to trip. My assumption though is that the Jetson is under some kind of load and not idle.
Thank you, I was running the jetson copilot example from here: Jetson Copilot - NVIDIA Jetson AI Lab
I will play with the setup a bit more and report back what I find.
Regards
