I have problem to program MKL25Z128VFT4 MCU. The design isn't change at all. However until recent purchase new MKL25Z128VFT. I have program issue with SWD interface. The reset pin always toggling.
The IO level 1.8 V is expected. However due to the toggling. it never reaches to 1.8v that cause me cannot program the chip.
The capture is from reset pin.
Here is schematic:
Hi David,
Before answer your question, I'd like to confirm some things with you.
1. Was it works after you use the original MCU to replace the new MKL25Z128VFT4?
2. I was wondering if you can share the screenshot of the error message when you program the MCU.
I'm looking forward to your reply.
Have a great day,
Ping
