I’ve read information about GPU power gating here: Thermal sensor data error in AGX Orin
All of my Orin AGXs running Jetpack 5.1 [L4T 35.2.1] exhibit this behavior. That is, the GPU temp sensor reads -256000 when the GPU isn’t in use. But I have one Orin AGX running Jetpack 5.0.1 [L4T 34.1.1] where the GPU temp can be read at any time even with no GPU processes running. I am trying to find an explanation in this difference in behavior. Can it be explained by the firmware difference? The Orin running Jetpack 5.0.1 is a 32 GB model and the rest are 64 GB models.
