Hi, Guys,

I need to monitor the Xavier AGX SOM’s real-time temperature, If is there a inside AD to capture and output the temperature? How can I get it?

Thanks,

hello yhp,

may I know what’s your actual use-case,
you may enable tegrastats utility to monitor the reported statistics.
thanks

Thanks Jerry for your reply.

We need to capture the temperature inside the Xavier module by the MCU which on carrier board via I2C bus, and the value will be as one of the input factors to control the fan speed.
So, How can I access the Xavier SOM’s temperature via I2C bus?

Thanks,

hello yhp,

you may enable tegrastats utility for checking that. it’s checking temperature sensor via thermal_zone for the results.
please also refer to Thermal Management in BPMP for more details.
