Hi, I am working with a S32K144. I plugged in the board yesterday into 12V, and saw some blinking in the reset light. Now I don't have power to the board. When I plugged into USB without power, I see 1 green LED. When I enable power through 12V or USB, the board gets really hot. 

Any help would be appreciated. 

Thanks!

Hi @josephcoorey,

Which chip is heating on the board?

I reckon it is the S32K144 MCU since it gets hot regardless of the power source.

I'm afraid the MCU has been damaged.
