I'm trying to create a simple program on an Atmega328p. When I include only the main function it works fine, but adding another function (even without calling it) causes the microcontroller to freeze (the light doesn't blink at all).
I've narrowed it down to simply adding an empty function. The below freezes - by simply commenting out the function it works fine (light blinks).
#include <util/delay.h>
#include <avr/io.h>

Figured it out - it was because I was passing the MCU type only in the compiler stage, but not in the linker stage.
