Is ESP32-S2 SPIFFS not supported with Arduino Framework?

Hi everyone -

I’ve been trying to get SPIFFS working on an ESP32-S2-MINI-1 module for the past 24 hours with no luck. Everything builds and uploads fine, but I get the following error after restarting:

E (15984) SPIFFS: mount failed, -10025
[ 16439][E][SPIFFS.cpp:114] format(): Formatting SPIFFS failed! Error: -1
[ 16439][E][SPIFFS.cpp:89] begin(): Mounting SPIFFS failed! Error: -1

And here’s my platformio.ini file contents:

[env:esps2]
platform_packages = 
	framework-arduinoespressif32 @ https://github.com/espressif/arduino-esp32.git#2.0.0-alpha1
platform = espressif32
board = esp32doit-devkit-v1
framework = arduino
board_build.mcu = esp32s2
monitor_speed = 115200

Has anyone had any success using SPIFFS with an ESP32-S2 using PlatformIO / Arduino-ESP32 Framework?

I have got it to work by set “flash_mode”: “qio”, in the board file. (same thing as @pattobrien) This will break the boot process of the esp32s2. So i need to flash the bootloader seperate after the upload within platformio. like this esptool.py --chip esp32s2 --port /dev/ttyUSB12 write_flash 0x1000 bootloader_qio_80m.bin, havent figured out why it breaks but anyway

Since some of the comments here are getting a bit old (and I believe framework has been updated in the mean time):

Reflashing the “qio” bootloader as described by @sweproj here above solves LittleFS-problem for me: https://github.com/platformio/platform-espressif32/issues/546#issuecomment-904811339

Only flashing with “qio” bootloader does not work. You need to flash with “dio” bootloader first, then reflash “qio” bootloader.

I use S2 bootloaders from here: https://github.com/espressif/arduino-esp32/tree/master/tools/sdk/esp32s2/bin
