CPU/GPU Thermal Condition Monitoring

Hi guys,

I am working on a project with the Xavier NX system, and I would like to measure the temperature status of the CPU / GPU during the operation. Is there a way/command I could use to monitor the temperature and record the data as a reference for my development with the Xavier NX itself? As I understand, there should be a thermal sensor attached to the board for the safety control through the firmware, am I right?

Thanks a lot!

hi @s.lee.1

Can you please try this to check the temperature status

$ cat /sys/devices/virtual/thermal/thermal_zone*/temp
and this script can also help you GitHub - MartinMatta/Jetson-Nano-temperature
to get more idea about thermal sensor on jetson please refer this doc https://docs.nvidia.com/jetson/l4t/index.html#page/Tegra%20Linux%20Driver%20Package%20Development%20Guide/power_management_nano.html#wwpID0E04G0HA

Thank you

Thanks a lot for your help. WIll give it a shot of testing later on.

For the sensor measurement point, is there any other measurement points on the board / SoC apart from the CPU that I can record through the sensor? If so, how can I find them out?

Thanks a lot!
