Hello, I’m attempting to read the temperature of the GPU in the Orin AGX developer kit using jtop. However, when connecting to the machine over SSH, the temperature of the GPU sometimes reads an actual temperature, but sometimes will say OFFLINE. Why would this be occurring?

Hi, I think this topic will be better suited for the Jetson category. I will move it over for you.

Hi,
The latest release is Jetpack 5.1.2. If you use previous release, please upgrade and give it a try.
If the issue is present on Jetpack 5.1.2, please run sudo tegrastats and check if you observe the issue. The information in jtop is from tegrastats
I connected over SSH to a devkit that is running 5.1.2, and it shows this:
test@ubuntu:~$ sudo tegrastats

Note this: GPU@-256C. The GPU temperature here is not being filled correctly.
Hi,
Please check
Jetson AGX Orin FAQ
Q: Why thermal zone/tegrastats reports -256C?
If the engine is not in-use, it is power gated and there is no thermal information.
