Jetpack 4.4 missing /etc/sensors.conf file for Xavier AGX

After the update to Jetpack 4.4 the /etc/sensors.conf looks to be missing, and the lm-sensors “sensors” app fails to display names and values for all sensors.

Where would this be archived that I can restore it?

It should be “/etc/sensors3.conf”, and not “sensors.conf”. I have this on one of my Jetsons (I renamed it sensors3.txt so the forum would accept it):
sensors3.txt (10.1 KB)

The package providing this:

# dpkg -S /etc/sensors3.conf 
libsensors4:arm64: /etc/sensors3.conf

Thanks - I had actually discovered this. Now my frustration is that there is no output

$ sudo sensors
thermal-fan-est-virtual-0
Adapter: Virtual device
temp1:        +30.3°C

Before I upgraded to Jetpack 4.4 there was a lot more output. Could you postulate why the output is lacking?

This is not an answer to your question, but you can also get these from command line:

cat /sys/class/thermal/thermal_zone*/type
CPU-therm
GPU-therm
AUX-therm
AO-therm
PMIC-Die
thermal-fan-est

cat /sys/class/thermal/thermal_zone*/temp 
39500
38000
38500
38000
100000
38650

temperatures are in milliCelsius. PMIC-Die showing 100°C is normal.

Hi @Honey_Patouceul

Thanks, it worked. Just curious, since PMIC temperature exactly remains the same 100C and no change in it.

Does Thermal-fan-est is used to estimate the output PWM of Fan or anything else ?

100 degrees C is a trip point for the PMIC and does not reflect the actual temperature.
