All the debugger does is wait a little but so the serial port comes up and then it allows Serial.begin()

So without the debugger the Serial.begin() might cause a crash because it might not exist.

Try moving your Serial.begin() to after your while loop that waits for Serial to be valid.

Code
Select All
void setup() {
	// start serial port at 9600 bps and wait for port to open:
	//>>>> move to after while{} >> Serial.begin(9600);
	while (!Serial) {
		; // wait for serial port to connect. Needed for native USB port only
	}
	Serial.begin(9600); //<< moved to here
}

void loop()
{
	Serial.println("Hello world");   // send an initial string
	delay(300);
}


Does this make sense? It is normally how this type of serial/usb port works.

Another point is that the code while (!Serial) {} will wait until you open the Serial Monitor.

If the Serial monitor is not open then the board will not start.

Do you know how to open the Serial monitor without debug? Icon on tool bar?
