I.mx6ul evk critical temperature reached

[vikneshwarthand]

Hi,

we are using the I.MX6UL evk board for development.

we pulled the codec MAIN mic bias voltage to 12v externally to test with the external mic and it worked well. but after some time, the board started throwing the message "temperature is exceeding" so immediately we turned it off and tried powering up after some time. again during the bootup, it is throwing  "temperature exceed so shutting down " so we turned off the device and started testing the board for short in the power lines but nothing is found. 

we are stuck. so don't know how to recover the SOM board. so please help us. 

we are attaching the image of the circuit chage we made and debug port message window. please refer to it and reply ASAP .@

Hi Vikneshwar

most components are 6.3V rated so they may be damaged by applying 12V.

So there is possibility that processor was also damaged, you can replace it

or cpu/baseboard.

Best regards
igor
