I'm on Win10, Arduino, trying to write a file to an esp32-s2 and get the message below. It also fails when using the command line esptool.py.
esptool.py v3.0-dev
Serial port COM3
Connecting.....
A fatal error occurred: This chip is ESP32-S2 not ESP32. Wrong --chip argument?
SPIFFS Upload failed!

This error means that esptool.py was passed the "--chip esp32" command line argument, but the chip is actually ESP32-S2.
Are you sure the Arduino settings are correct for an ESP32-S2 target?

Are you using the fs plugin from @me-no-dev or @lorol?
https://github.com/lorol/arduino-esp32fs-plugin library has been updated to support esp32-s2

I was using me-no-dev, but lorol worked! Thank you so much, I 'wasted' two days on this and was dreading going back to the ESP32 and shift registers due to lack of usable ports with wifi.
Much appreciated! Happy holiday to you.

Did you select the S2 as your target?
