Whenever the system gets powered on, or whenever I download a new program to the Arduino, the blue LED blinks. This is no a problem per se.
The Problem is that pin D13 (where the led is connected) needs to be used by my application and I cannot afford to have it blinking every time the machine powers up.
How can I disable this feature?

Hi,
Thanks for your support.
According to the standard Arduino design, there is a LED link with D13, so as LattePanda.
If you don't need a D13 LED, we suggest you move the LED components or exchange to another pin.
