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.
