ESP32 Forum

Hello,

I am using a ESP32-C3 with two type C USB connectors.
In the back of the PCB, it is written AI-C3.

I asked to the Aliexpress seller, he told me that the chip is ESP32-C3 Mini1

Do you think, is it a Ai-Thinker esp32-C3-M1-I-Kit????

I have made my project considering that the board is esp32-c3-devkitm-1.

When i build the objects, i have an error.

I tried different things to resolve my problem without success!

Could you help me please

Kind regards

joseMiguel

}
===========================================================================

In the system environment variables i have deleted
IDF_PATH C:\ESP\esp-idf-v5.0
IDF_TOOLS_PATH C:\Users\josem\.espressif

I have kept the
EXTENSION_PATH C:\Users\josem\.vscode\extensions\espressif.esp-inf-extension-1.5.1

Does i need to remove also the EXTENSION_PATH environment variable ?

Thank you, for reading

Hi guys,

I found the solution,

1) In the directory C:\Users\josem\.platformio\penv\Lib\site-packages, there were only the directory <pyparsing-2.3.1.dist-info>
So, i have removed that directory

2) And in the directory C:\Users\josem\.platformio\penv\Scripts I have typed
pip install pyparsing
Now there are two directories, as a normal installation or setup
<pyparsing> and
<pyparsing-3.0.9.dist-info>

So i succeed to generate an .elf file

Thank you for having read this topic

Have a nice week

joseMiguel
