Not able to turn screen on using M5Stack Core2 ESP32 IoT

Libraries

I have a working Core2 for AWS, it was working perfectly fine, then I start playing with some code, I tried this

M5.begin(true, true, true, true);

M5.Power.begin();
M5.Lcd.setTextSize(2);
M5.Lcd.printf("\nConnecting to %s", WIFI_SSID);

But the screen won’t turn on, I can see the logs that is working on the serial port.

My platformio.ini

[env:core2foraws]
platform = espressif32
framework = arduino
board = m5stack-core2
monitor_speed = 115200
upload_speed = 2000000
upload_protocol = esptool
board_build.f_flash = 80000000L
board_build.flash_mode = dio
build_unflags = -mfix-esp32-psram-cache-issue

build_flags =
  -Os
  -pipe
  -Wall
  -std=gnu++11

lib_deps =
  knolleary/PubSubClient@^2.8
  ssilverman/libCBOR@^1.6.1
  skhaz/ZSTD@^1.0.2
  M5Stack
  NTPClient

My code

#include <M5Stack.h>

static const char WIFI_SSID[] = "My WiFi";
static const char WIFI_PASSWORD[] = "hakunamatata";

void setup()
{
  M5.begin(true, true, true, true);

  M5.Power.begin();
  M5.Lcd.setTextSize(2);
  M5.Lcd.printf("\nConnecting to %s", WIFI_SSID);

  Serial.begin(115200);

  WiFi.mode(WIFI_STA);
  WiFi.begin(WIFI_SSID, WIFI_PASSWORD);

  while (WiFi.status() != WL_CONNECTED)
  {
    delay(100);
  }

  Serial.println();
  Serial.print("Connected to: ");
  Serial.println(WIFI_SSID);
  Serial.print("IP address: ");
  Serial.println(WiFi.localIP());
}

void loop()
{
  M5.update();

  delay(1000);
}

What I am doing wrong?

Solved adding the line

M5.Axp.SetLcdVoltage(2800);
