I need help with arduino ESP8266

[domino254cz]

Help me my arduino is not working here is the error:

Did you select the ESP8266 and its port in your IDE?

Hi @domino254cz ,

welcome to the arduino-forum.

The arduino-IDE can log a lot of more information about the compiling/upload-process
adjust the IDE like explained int this tutorial

Make experienced users help: two ways to quickly post code as a code-section

Hi newcomer, This thread wants to show you how you can speed-up getting helpful answers with small effort. If you manage at least to post this way. You have the sympathy of the experienced users. If you are willing to invest another 20 minutes these 20 minutes extra-time will save you a minimum of 200 minutes to finish your project. always post your full sketch. As a code-section from the very first to the very last line A code-section has a small height => keeps your posting "short" but e…

I moved your topic to an appropriate forum category @domino254cz.

In the future, please take some time to pick the forum category that best suits the subject of your topic. There is an "About the _____ category" topic at the top of each category that explains its purpose.

This is an important part of responsible forum usage, as explained in the "How to get the best out of this forum" guide. The guide contains a lot of other useful information. Please read it.

Thanks in advance for your cooperation.

Hi @domino254cz. I'm going to ask you to post the full verbose output from an upload attempt.

---

This procedure is not intended to solve the problem. The purpose is to gather more information.

---

Please do this:

1. Select File > Preferences... (or Arduino IDE > Settings... for macOS users) from the Arduino IDE menus.
   The "Preferences" dialog will open.
2. Uncheck the box next to Show verbose output during: ☑ compilation in the "Preferences" dialog.
3. Check the box next to Show verbose output during: ☐ upload.
4. Click the "OK" button.
5. Attempt an upload, as you did before.
6. Wait for the upload to fail.
7. You will see a "Upload error: ..." notification at the bottom right corner of the Arduino IDE window. Click the "COPY ERROR MESSAGES" button on that notification.
8. Open a forum reply here by clicking the "Reply" button.
9. Click the <CODE/> icon on the post composer toolbar.
   This will add the forum's code block markup (```) to your reply to make sure the error messages are correctly formatted.
   
10. Press the Ctrl+V keyboard shortcut (Command+V for macOS users).
    This will paste the error output from the upload into the code block.
11. Move the cursor outside of the code block markup before you add any additional text to your reply.
12. Click the "Reply" button to post the output.

You seem to use a very old esptool
esptool v0.4.9 - (c) 2014 Ch. Klippel ck@atelier-klippel.de

If I compile for an ESP8266 i get this upload-log

your esptool: esptool v0.4.9
most actual: esptool.py v3.0

So one thing to try is to update your ESP8266-board core-files to version 3.1.2
In Arduino IDE Version 1.8.19 this looks like this

Thanks it works now!
