I have a few Jetson Orins. I am using a docker image to run my custom scripts, DWS to remote access, and crontab jobs to connect to the internet via Simcom Wvan Sim 7600x automatically.
No matter what I do, I lose connection to the device after some duration. The device is trying to reboot itself, but it’s not going online.
I didn’t face the same issue on Jetson NX or Nano. When I moved the device’s SD card to another Jetson board, the new board was also not working. When I reinstall the device by using Jetson SDK, it works. After a while, I am still losing the device.
I think two days ago, I lost the 5th device; what could be the reason? Does the Jetson Orin have a chronic issue that might cause this?
I am still not sure about what’s happening. I got more information from our team about the issue. In this particular case, we lost connection to the camera, which is mounted on the device. After that, we restarted the device, but it never booted up again.
It should be a shutdown because the fan connected to the device stopped working, like the power is completely shut down.
I tried to restart the device many times manually, but it’s not responding at all. When I replaced the SD card, everything worked fine so the power source should be fine.
I activated the serial console as you described, and it worked, and I have connection to the device. However, it’s not throwing any errors. I tried to go to the following path to check the logs cd /var/log, and I received the following line -bash: cd: log: Structure needs cleaning.
This is the output I saw as soon as I logged in to the device:

How can I get more information from the device? The strangest thing is that I didn’t change anything about the custom scripts I implemented. So, while the device was in operation, suddenly, I lost the device, and this kept happening.
Please really try to use the method I provided to dump log from micro usb port (if this is NV devkit).
Using syslog or /var/log do not help clarify anything. syslog does not record the error log but my method from micro usb port will.
Your method to tell a board is shutdown or reboot is not correct either. No one can judge the board status by checking the fan is running or not. I can create a situation that the fan is not running but board still powers on.
Also, are you always booting the jetson from a sdcard?
It should be the dev-kit. I couldn’t see anything after using the following command minicom -D /dev/ttyACM0 -8 -b 115200. I connected the board to the laptop via type-c. This is my device:
