Hi, our device recently displayed an overcurrent warning. I’ve read some posts and it seems replacing the power adapter may resolve the issue. Does NVIDIA officially recommend a specific power supply?
Also, what are the triggering conditions for overcurrent? Can I choose the appropriate power adapter based on these triggering conditions?
On Nano or Orin Nano?
Which JetPack SW?
This problem occurred in Nano with jectpack 4.6.6 and in Orin Nano with jectpack 6.2.
You could start from reading the document first.
I don’t really think the case in Orin Nano would be same as Jetson Nano. I mean OC alarm has different kinds too. Not every OC alarm is same.
If you are speaking of an overcurrent message in the dmesg logs, then this likely is unimportant and not what it sounds like. Jetsons have different power models available so the end user can set a maximum power consumption. If any computing requirement would exceed this value, then the clocks and/or core count are reduced to remain within that power model. The message is bad because they all say “overcurrent”. Only in the max power model does this mean it is reducing due to hardware limitations; the max power model, if producing too much heat, has the same message, but the same code to reduce clock speeds is what is triggered. This is in no way a power failure. For such messages it also is never the power source in question. If you post a specific log line, then it’d be possible to know if it is a power model issue or something else.
