How to configure PlatformIO for LittleFS (ESP32)
You can configure PlatformIO to use the LittleFS filesystem as opposed to the default SPIFFS using
board_build.filesystem = littlefs
If you are ussing arduino-esp32, you might also need to specify to use a recent arduino-esp32 framework version, but I suggest to first try it out without using that option:
platform_packages = framework-arduinoespressif32 @ https://github.com/espressif/arduino-esp32.git#2.0.5
Full platformio.ini example
[env:esp32dev]
platform = espressif32
platform_packages = framework-arduinoespressif32 @ https://github.com/espressif/arduino-esp32.git#2.0.5
board = esp32dev
framework = arduino
board_build.filesystem = littlefs
monitor_speed = 115200
