SK-TDA4VM: Temperature read cmd

Jaecheon Yoo

Part Number: SK-TDA4VM

Hi, I am JC.

I'd like to know temperature in Celsius of J721E(main chipset) in SK-TDA4VM.

Please share command to access/read the information if possible.

And is there any performance limiting or AVS limiting in SDK of SK-TDA4VM when temperature rises above any kinds of defined point ?

I wonder how the current SDK refers the temperature information.

Hi JC,

Cat /sys/class/thermal/thermal_zone*/temp should give you temperatures of all the zones on the SoC.

No passive cooling support. So there's no performance limiting. We do have thermal shutdown enabled around 123c.
