Title: MK60DX256VLL10 RESET pin
Post by: ABBASID on June 01, 2021, 02:25:41 PM

I have designed a circuit which uses MK60DX256VLL10 based on its development kit "TWR-K60D100M-KIT" . I have pulled up the RESET pin (pn # 52) as shown in figure but when I power up the circuit, RESET pin shows 0.9V due to which this controller is not detected in MCUExpresso for coding. I increased the value of capacitor from 100nF to 300nF but still voltage rises only to 1.1V. Any possible solution for this problem would be highly appreciated.

I connected EZP_CS_b port to the ground of microcontroller for just a second and then removed this grounding. Afterwards, I checked the Reset pin and it was showing 3.3V and finally controller was out of reset state. Then I was able to sucessfully download and debug my code to this controller.
