Sporadic iMX6DL Thermal shutdown

Question asked by Erez Steinberg on Jun 30, 2015
Latest reply on Jul 1, 2015 by Yuri Muhin

I have a custom board with iMX6DL and Linux 3.14.28.

 

The board was idle (only serial console working) -- and suddenly I received a thermal warning..

 

Touching the iMX6DL -- it was running very cold (no way it was 175 degrees!)

 

Any idea why this would happen?

 

 

Sincerely,

Erez.

 

 

Dump on the console:

 

System is too hot. GPU3D will work at 1/64 clock.
