MIT licensed, see LICENSE.md

LittleFS uploader compatible with Arduino IDE 2.2.1 or higher. For use with the Raspberry Pi Pico RP2040 Arduino core arduino-pico, the community ESP8266 Arduino core and the community ESP32 Arduino core.

Usage

[Ctrl] + [Shift] + [P], then "Upload LittleFS to Pico/ESP8266/ESP32".

On macOS, press [⌘] + [Shift] + [P] to open the Command Palette in the Arduino IDE, then "Upload LittleFS to Pico/ESP8266/ESP32".

Glitches

The first sketch auto-opened by the IDE presently may have corrupted state which causes uploads to fail. To work around this, you can change the board once (to anything) and then change it back to your proper board. You can also open another sketch, close the auto-opened one, then re-open it.

A fix is already in the Arduino repository for this issue.

If you get:

A fatal error occurred: Could not open <serial port>, the port doesn't exist
ERROR:  Upload failed, error code: 2

Make sure that you close any open Serial Monitor windows.

Installation

Copy the VSIX file to ~/.arduinoIDE/plugins/ on Mac and Linux or C:\Users\<username>\.arduinoIDE\plugins\ on Windows (you may need to make this directory yourself beforehand). Restart the IDE.

Arduino Nano ESP32 Notes

This board uses DFU mode by default and requires several steps to make it compatible with this plug in. See the Arduino Forum post for the necessary steps: https://forum.arduino.cc/t/best-method-for-utilizing-on-board-flash/1222469/15
