[FAQ] TDA2PXEVM: Temperature calculation at runtime for hlos usecase

Hi Chinmayee,

I believe you have Linux on TDA2P. Once you have booted to Linux prompt
you can read the temperatures of various thermal zones runtime. The below
is how you can check various thermal zones on your SoC:

root@am57xx-evm:~# cat /sys/class/thermal/thermal_zone*/type
cpu_thermal
gpu_thermal
core_thermal
dspeve_thermal
iva_thmal

Below is how you read out the temperature runtime:

cat /sys/class/thermal/thermal_zone*/temp
51400
51000
51800
50600
52200

The units of above temperature is milli degree centigrade. So we can map:

cpu_thermal zone @ 51.4 C
gpu_thermal @ 51 C

& so on based on the index. Hope this answers your question. Please resolve the issue if you have no further questions
on this topic.

Best Regards,
Keerthy
