SCM IMX6D/Q heating issues on Android/Linux.

[ganeshskandha]

Hi,

The SCM IMX6D/Q board heats up a lot when using GPU. It is consistent across Linux and Android. 

Linux build : imx-4.1.15-2.0.0_ga release

Android : Marshmallow 6.0.1_2.1.0

On Linux, when I run glmark2 (multiple instances), the CPU reaches > 85C in ~ 5 minutes

On Android, I run skycastle (a GPU benchmark) and the CPU reaches > 85C in less than a minute.

Are there any heatsink solutions available for this SCM IMX6 board ?

What is the recommended thermal solution for a POP package ? (Is there any documentation for that)

To design a heatsink, We would like to know the thermal resistance of the Processor + POP package combination

Thanks,

Ganesh

Try to operate the chip in LDO bypass mode to save power consumption and reduce thermal under high load:

Hello Ganesh,

There is some information regarding the SCM thermal profile but I’m afraid it’s not publicly available so it cannot be shared on this Communities. Would you please open a Case on nxp.com/support to receive the available information?
