Our situation is:  we have the /RESET pin pulsing at about 20KHZ  (chip resetting itself) , we haven't yet programmed the chip (can't connect jtag). Can you provide any suggestions to what circumstances would cause the this reset reaction. We have looked at 3 new boards and they all are doing the same thing. Any help you can provide would be greatly appreciated.

Hi, Frank

For an empty chip, MCU will output square waveform on reset pin. But you can run into debug mode with debug tools. Would you please help to tell me which debug tools you used? If possible, would you please provide your schematic? I would like to check it for you.

Best Regards

Paul
