Jetson nano reboots randomly

Autonomous Machines Jetson & Embedded Systems Jetson Nano

I use Jetson Nano for a data collection and GPU inference task. These tasks are perform in parallel, so while the Nano captures de data (images) I also do inferences with the images (yolov5 in pure torch1.81), save data to a db and delete the infered image.

This pipeline has gone perfect for some days, but after 10 days maybe it started to fail, I check with last reboot if the nano reboots and it seems that it randomly does it while doing the job (random because one day it reboots after 5 hours of work, and other it reboots after 30 minutes).

I am using the power supply requested (5v-4A), also the fan is setted to default. the environment where the jetson is working is a laboratory (monday to friday 9am-6pm with air condition, others no and closed with no windows)

Maybe this is due to overheating? Is there a way to check a log? like heat log or error before rebooting?

Thanks in advance.

hello fnando1995,

as you can see, JTop has gather the thermal info also.
however, you may enable tegrastats utility, enable the --logfile options to dump the logs file to gather the reported statistics.
in addition, please also setup a terminal. please running $ dmesg --follow to catch the instant kernel logs.
please check what’s the actual failure to cause Nano reboot randomly.
thanks

Had you turn on bluetooth on th Nano? Have a try to turn off the bluetooth may get rid of the reboot by itself issue.
