Please post entire verbose error log in a CODE tag. Also tell us what board is selected in the IDE. That's a start.

BitSeeker · April 22, 2026, 8:28pm

Hmm, definitely something.

wang963852 · April 23, 2026, 1:20am

Board is AirM2M_CORE_ESP32C3,
that's all the error log .

yes, something wrong with the loading.
it give me a surprise.

ptillisch · April 23, 2026, 1:25am

Hi @wang963852. I'm going to ask you to provide 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:

Select File > Preferences... (or Arduino > Settings... for macOS users) from the Arduino IDE menus.
The "Preferences" dialog will open.
Uncheck the box next to "Show verbose output during: ☑ compilation" in the "Preferences" dialog.
Check the box next to "Show verbose output during: ☐ upload".
Click the "OK" button.
The "Preferences" dialog will close.
Attempt an upload, as you did before.
After the upload fails, you'll see a button on the right side of the orange bar in Arduino IDE: Copy error messages. Click that button.
This copies the full output to the clipboard.
Open a reply here on this forum topic by clicking the "Reply" button.
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.

Code block icon on toolbar390×118 4.25 KB
Press the Ctrl+V keyboard shortcut (Command+V for macOS users).
This will paste the error output from the upload into the code block.
Move the cursor outside of the code block markup before you add any additional text to your reply.
Click the "Reply" button to publish the post.

Thanks Ptillisch, i will follow this with home computer when i go back home .

sonofcy · April 23, 2026, 12:21pm

Sorry, no idea what that is. Please follow post 6 in order to do as I asked, then maybe someone can help.

It looks like your ESP32 board package might be corrupted.

Using boards manager you might try removing the ESP32 boards package from the IDE and then re-installing it to see whether that resolves the problem.

wang963852 · April 27, 2026, 2:33pm

this could not resolves the problem, i tried so many packages , it makes the same warning.

ptillisch · April 28, 2026, 12:22am

Hi @wang963852. When you upload a sketch to an ESP32-based board, Arduino IDE uses a tool named esptool. This tool was created by Espressif, the company that makes the ESP32 microcontrollers.

The error you are encountering:

seems to be caused by esptool having a dependency on a DLL that is not provided by your system.

I see you are using the very old version 2.0.12 of the "esp32" boards platform:

(the latest version is 3.3.8)

This also results in a very old version of esptool being used:

(the latest version is 5.2.0)

I don't have any specific evidence of this, but it is possible that the problem you are encountering is caused by using such an old version of esptool. So it might be worth trying to update your installation of the esp32 boards platform. You can do that by following the instructions here:

https://docs.espressif.com/projects/arduino-esp32/en/latest/installing.html#installing-using-arduino-ide

There is something you should be aware of:

The developers of the "esp32" boards platform introduced some significant breaking changes in the 3.0.0 release. You might find that some sketches and libraries that work with your outdated version of the platform no longer work with the latest version. In regards to compatibility of the libraries, the situation should not be too terrible now, since two years have passed since the 3.0.0 release and so the library developers have had quite some time to update their libraries for compatibility with the new version. My recommendation is to just go ahead and update to 3.3.8. If you don't encounter any problems, or if you encounter problems but find that you are able to resolve them, then you are all set. If you find this introduced insurmountable problems, you can then install version 2.0.17, which is the last version before the breaking changes. 2.0.17 is a couple years outdated, but it is at least an upgrade from the version 2.0.12 you are using.
