Arduino SMD Running old code

[FaizeenHoque]

Hi!

I have an Arduino SMD board on which I uploaded code for an NFC card reader project. Later, I decided to use the Arduino for a different project. However, when I try to upload new code, the Arduino still runs the old card reader program. I enabled verbose output during the upload, and it even shows that the upload was successful, but the Arduino continues to run the old code.

This repo is not for the Arduino AVR devices. I suggest asking on the official forums: https://forum.arduino.cc/
