What does this error means?

Hello, recently I bought ESP32-SOLO-1. When I want to upload any kind of a program on it I see in the serial monitor this:

Rebooting...

Thanks for any kind of help :)

Nice regards, Tilen

I think the error is pretty clear. You're running code on a single-core chip (the board you're using has an ESP32-S0WD chip, which is a single-core variant of the dual-core ESP32), but the code you're trying to run was compiled for a dual-core CPU (most likely an ESP32).

As far as I could find, the ESP32-S0WD is not supported by the ESP32 Arduino Core: https://github.com/espressif/arduino-esp32/issues/3324

Oh, thanks for your help :)
