Hℹ,
We encounter the same problem on ORIN NANO/JP 5.1.2，when running isaac_ros_ess.
“System throttled due to Over-current”
And the results of command
grep “” /sys/class/hwmon/hwmon*/oc* are:
/sys/class/hwmon/hwmon1/oc1_event_cnt:0
/sys/class/hwmon/hwmon1/oc1_throt_en:1
/sys/class/hwmon/hwmon1/oc2_event_cnt:0
/sys/class/hwmon/hwmon1/oc2_throt_en:1
/sys/class/hwmon/hwmon1/oc3_event_cnt:489
/sys/class/hwmon/hwmon1/oc3_throt_en:1
BTW， NANO runs in 15W power mode.
Possible to fix it?
Hi jiangjie1,
I’ve moved your topic to correct category for Jetson Orin Nano. (it was in Jetson Nano)
Are you using the devkit or custom board for Orin Nano?
It seems you hit OC event caused from instantaneous high current.
May I know what are you running on the board?
You may check the power log and create a custom nvpmodel configuration for your use case.
Hℹ Kevin,
We are using a custom board, not devkit.
The application is isaac_ros_dnn_stereo_depth,
which produces the disparity from an argus stereo camera.
The OC event occurs on Channel 3 (oc3_event_count is about ~400)，
does it mean the current of channel 3 is over the current limit , which is set by
/sys/devices/platform/c240000.i2c/i2c-1/1-0040/hwmon/hwmon3/curr3_crit ?
Attached is a power log which contains an OC event / warning.
But I’m not sure which entry causes the OC event.
oc1.csv.txt (34.8 KB)
No,
OC1 means under voltage
OC2 means VDD_IN average power
OC3 means VDD_IN instant power
You can find more details in Jetson Orin Nano Series, Jetson Orin NX Series and Jetson AGX Orin Series

It seems you are using Orin NX 8GB (Model: P3767, SKU: 0003)
OC2 is 15W, OC3 is 20W
Could you add the following in /etc/nvpmodel.conf?

and run the following command to apply the change.
# nvpmodel -m 2
# reboot
# nvpmodel -q --verbose
(Model: P3767, SKU: 0003) should be ORIN NANO 8GB:
Is it possible to apply your new power mode to NANO 8GB module?
Sorry that it was my typo, you are using Orin Nano 8GB module.
Yes, please update and apply that nvpmodel configuration on your board.
