Hi all,


     I am using MK60FX512VLQ12 in bare-metal mode. Every 0.833ms it will perform ADC . The loop in the main() do some Key Scanning and

Uart Sending. No other features in its code. Now the K60 chip will be overheated(may be 60℃) after 20 minutes' running. If debug K60 with

J-link, it will be overheated(may be 90℃) in less time.

     The chip runs well and can be debugged.

     What could be the problem and how can I identify it?
