ESP32 - Little FS implementation

PlatformIO IDE
,
1

Hello,

I tried to implement the littleFS to an ESP32 project without succes.

I use the loro git littlefs implementation, I build the file system (with a file in data), I upload the filesystem image to my esp32, and I test it with a sample program but I get every time a " begin(): Mounting LITTLEFS failed! Error: -1

Does anyone have a sample prog that run on ESP32 ? (I use to run littlefs on esp8266 correctly)

thank you
Multinet.

No – since some time now, Arduino-ESP32 and the Espressif32 integration have native LittleFS support with the library built-in to the core and native PIO support.

As a first try, please use the platformio.ini

[env:esp32dev]
platform = espressif32
framework = arduino
board = esp32dev
board_build.filesystem = littlefs

with this src/main.cpp and this data folder. Use the “Upload File System image” project task as normal to build + upload the LittleFS image, then “Upload & monitor” the firmware.

Is your Espressif 32 platform up-to-date? Please open a CLI and execute

pio pkg update -g -p espressif32

and retry.

For anyone else who may run across this issue:

Following the above instructions did not solve the issue for me, but I found a solution:

Add this line in your platformio.ini file:

lib_ldf_mode=deep

Hope this helps someone :+1:

Edit: After I posted this I figured out that my file structure was not set up properly. I was able to restructure my lib files and then I was able to compile without the line I posted above.

Hi,
for an old project I used LITTLEFS on Arduino, I’ve moved this project on Platformio and I’m using the 3.2.0 version of espressif package.
There is method for using the tool also whit this vesion?
