[SOLVED] Problem uploading sketch to arduino uno/esp8266

Problem uploading sketch to arduino uno/esp8266

Getting this error while uploading:

Arduino: 1.8.13 (Windows Store 1.8.42.0) (Windows 10), Board: "Generic ESP8266 Module, 80 MHz, Flash, Legacy (new can return nullptr), All SSL ciphers (most compatible), dtr (aka nodemcu), 26 MHz, 40MHz, DOUT (compatible), 1MB (FS:64KB OTA:~470KB), 2, nonos-sdk 2.2.1+100 (190703), v2 Lower Memory, Disabled, None, Only Sketch, 115200"

Sketch uses 265644 bytes (27%) of program storage space. Maximum is 958448 bytes.

Global variables use 27008 bytes (32%) of dynamic memory, leaving 54912 bytes for local variables. Maximum is 81920 bytes.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

This is the pin configuration:

Insted of the 3.3v im using a voltage regulator.
Also RX connected to RX & TX to TX.

Code:


#include <ESP8266WiFi.h>

void setup()
{
  Serial.begin(115200);
  Serial.println();

  WiFi.begin("username", "password");

  Serial.print("Connecting");
  while (WiFi.status() != WL_CONNECTED)
  {
    delay(500);
    Serial.print(".");
  }
  Serial.println();

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

void loop() {}

Someone suggested to ground the GPIO0, didn't work.
Tried installing different version of the Board:"Generic ESP8266 Module" still getting the same error.

The module works fine when working without the library using the Board:"arduino uno"
