Use ESP32_c2 with ArduinoIDE

Hi,

i have an ESP32-C2 that is not supported by default. I found this viewtopic.php?t=41902:
In recent versions of the code, I think C2 is included, but hidden.
But i don't understand what to do. I have this URL https://espressif.github.io/arduino-esp ... index.json in Additional Boards manager URL. The files are stored in "$USER/.arduino15/packages/esp32/tools/esp32-arduino-libs/idf-release_v5.5-07e9bf49-v1/". But there is no boards.txt.

Do i need to download the core from github then edit the boartds.txt and then install it from locale storage? Or copy the downloaded folder to somewhere?

Thx, Friedbert

It is not just hidden. The necessary bootloaders and libraries are not included, so you would need to build the framework with lib-builder or esp-idf, as posted on the repo main page.

Just use pioarduino community platform compatible with PlatformIO.
That will support the ESP32-C2
