Power led on, connection is ok, but no respond



Hello everyone, I'm really new for microcontrollers although I have some knowledge about c language. Well, the issue is my tiva c tm4c123g board's power led is on (only on led), also Stellaris ICDI DFU device and JTAG/SWD interface and VSP(com6) is ok and I tried CCS and LM flash programmer, they both erase flash and program again without any problem but the program does not run (e.g blinky, led does not blink or hello, I see nothing in the putty at com6 br 115200) I'm not sure but I tried this code accidentally before, a blue led was on because of the running program but then it turned off. The code is on processing

import processing.serial.*;
 
PFont font;
int pwmValue;
Serial mySerial;
int serialIndex = 0;
 
void setup() {
  font  = createFont("Arial", 32);
  size(300, 301);
  mySerial = new Serial(this, Serial.list()[serialIndex], 115200);
}
 
void draw() {
  background(200);
  if (mouseY > 44) {
    line(0, mouseY, 300, mouseY);
    pwmValue = int(constrain(-2.1*(mouseY - 172), -255, 255));
    fill(0);
  }
  else {
    pwmValue = 0;
    fill(70);
  }
  rect(0, 0, 300, 44);
  textAlign(LEFT, TOP);
  textFont(font, 16);
  fill(255);
  text("Current Speed: " + str(pwmValue), 9, 9);
  fill(255, 0, 0);
  text("Rollover to Reset", 160, 9);
 
  mySerial.write(str(pwmValue));
  mySerial.write("#");
  mySerial.write(str(pwmValue));
  mySerial.write(10);

// Graphing sketch


// This program takes ASCII-encoded strings
// from the serial port at 9600 baud and graphs them. It expects values in the
// range 0 to 1023, followed by a newline, or newline and carriage return

// Updated 18 Jan 2008

// This example code is in the public domain.
