i.MX6 CPU temperature is too high

[petertseng]

Hello,

In our custom board which is designed more closer to i.MX6Q SABRE SD.

When I normally boot into Android 4.3 system and enable stay awake keep for some time.

I get the CPU temperature:

root@sabresd_6dq:/ # cat /sys/class/thermal/thermal_zone0/temp                 

52

When the system does not execute any APK, the CPU temperature has been maintained at 53 ~ 49.

When executed Cactus Player, CPU temperature will be higher than 53.

Is that normal?

Thanks.

Regards,

Peter Tseng

Hi Peter

I think this can be considered as normal since VPU/GPU consumes

quite lot of energy. Some power consumption figures can be found in

below application note

AN4509 i.MX 6Dual/6Quad Power Consumption Measurement

Hi igor

But, when our system does not execute any APK, the CPU temperature has been maintained at 53 ~ 49.

Is it also normally?

PS: I did not use any heatsink on our i.MX6Q CPU
