My esp32 print weird characters but I do anything

I only want to print simple text but it print unilimited weird character and never stop, (when I remove Serial.print() it continues to print weird characters).

This is the weird text that loop

My code : 

void setup() {

}

void loop() {

}

I hope you can help me, thanks :)

UPDATE

I completely removed Serial.begin(9600) and Serial.print() and I still have the problem O_o

Solution

  • I just changed the Flash memory speed to 40MHz instead of 80MHz
