Esp32s3 N16R8 fails always with LittleFS

The partitions.csv should be in the same place as the platformio.ini

@sivar2311 I am currently using platform = espressif32@6.12.0. Should I switch to some other platform for e.g. the latest pioarduino? What version are you using? I would like to make my settings as close to you as possible.

24

That depends on your needs.

Usually I use the latest pioarduino espressif32-platform version.
But when I need Espressif Arduino 2.x (for compatibility reasons) I use the latest official PlatformIO espressif32-platform.

I ran the test with both latest versions without issues.

25

Ok. And do you also perform Upload Filesystem Image (for data folder) before flashing the code? I see that when I use SPIFFS, I am not getting any error. Only with LittleFS I am unable to work.

26

First, I just uploaded the sketch to see what would happen. I got an error message saying that the partition could not be mounted. This was to be expected, as there was no valid LittleFS file system in the partition yet.

I then created the file system and uploaded it. After restarting the ESP32, the partition was successfully mounted (as expected).

27

Yes, its only a name but show in LittleFS.h header file.

bool begin(bool formatOnFail = false, const char *basePath = "/littlefs", uint8_t maxOpenFiles = 10, const char *partitionLabel = "spiffs");

The default label of a littlefs partition is “spiffs”. You should name it that or tell the label name of the begin function.I think that was done for compatibility reasons.

I am having issues using littlefs with esp32s3-n16r8 as well using the Espressif 32 6.12.0 platform, platformio VS Code:

[env:esp32-s3-n16r8]
platform = espressif32
board = esp32-s3-devkitc-1-n16r8v
framework = arduino
monitor_speed = 115200

board_build.partitions = default_16MB.csv
board_build.filesystem = littlefs

upload_protocol = esp-builtin

build_flags =
    -D ARDUINO_USB_CDC_ON_BOOT=1
    -D ARDUINO_USB_MODE=1
    -DBOARD_HAS_PSRAM
	-D PIO_FRAMEWORK_ARDUINO_LITTLEFS

And I keep getting this on serial:

This is my partition table printed with esp_partition_get:

What platform version do you use / which one do you have installed?

This board definition is not included in the official PlatformIO espressif platform.

Where does this come from? (Looks like AI generated)

If you go with PlatformIO’s espressif32 platform (6.12.0) use this platformio.ini:

[env:esp32-s3-devkitc-1]
platform = espressif32 @ 6.12.0
board = esp32-s3-devkitc-1
framework = arduino

board_build.arduino.memory_type = qio_opi
board_build.flash_mode = qio
board_build.psram_type = opi
board_upload.flash_size = 16MB
board_upload.maximum_size = 16777216
board_build.partitions = default_16MB.csv
board_build.extra_flags = 
  -DARDUINO_USB_CDC_ON_BOOT=1
  -DBOARD_HAS_PSRAM

If you use pioarduino’s espressif32 platform use this platformio.ini:

[env:esp32-s3-devkitc1-n16r8]
platform = https://github.com/pioarduino/platform-espressif32/releases/download/55.03.35/platform-espressif32.zip
board = esp32-s3-devkitc1-n16r8
framework = arduino
build_flags =
  -DARDUINO_USB_CDC_ON_BOOT=1

The use of -DARDUINO_USB_CDC_ON_BOOT=1 is only necessary if you want to use the native built-in usb port instead of the UART usb port.

Try the LittleFS example provided by Espressif:
