Could someone help with the name of the each thermal sensor and where it is located on the TX1 module.
Reading /sys/devices/virtual/thermal/thermal_zone0/temp: [29000] 29.00
Reading /sys/devices/virtual/thermal/thermal_zone1/temp: [27000] 27.00
Reading /sys/devices/virtual/thermal/thermal_zone2/temp: [28000] 28.00
Reading /sys/devices/virtual/thermal/thermal_zone3/temp: [24500] 24.50
Reading /sys/devices/virtual/thermal/thermal_zone4/temp: [100000] 100.00
Reading /sys/devices/virtual/thermal/thermal_zone5/temp: [34250] 34.25
Reading /sys/devices/virtual/thermal/thermal_zone6/temp: [33000] 33.00
Reading /sys/devices/virtual/thermal/thermal_zone7/temp: [27500] 27.50

Hi rkumar, please refer to the Jetson TX1 Thermal Design Guide for further documentation and diagrams about the TX1 thermocouples.

If you cat the the “type” entry found under each thermal zone, that should provide a textual description of each sensor:

$ cat /sys/devices/virtual/thermal/thermal_zone1/type
cpu-therm
$ cat /sys/devices/virtual/thermal/thermal_zone1/temp
35000

Hello, looking the different types of thermal zone I obtained the following:

$ cat /sys/devices/virtual/thermal/thermal_zone*/type
AO-therm
CPU-therm
GPU-therm
PLL-therm
Tdiode_tegra
PMIC-Die
Tboard_tegra
thermal-fan-est

I looked for information in the manual of Tegra X1 (http://developer.nvidia.com/embedded/dlc/tegra-x1-technical-reference-manual), but there is the following table: https://imgur.com/a/Eqbm2.

I would want to know the relationship between the terms used in this table (TS_AO, TS_PLLX…) and the types obtained in the Jetson TX1.

Thanks
