LittleFS

Only on T & N at the moment

LittleFS is a flash FS for embedded devices which allows you to store files on your device.

As of 2022-11-01, it's default size is 32 KBytes.

The LFS flash shares with the OTA flash area, but by reducing the size, it does not get overwritten by OTA.

The following commands operate against the LFS:

lfssize - log the current size and configured size of the LFS flash

lfssize 0xnnnn - configure a new size and store in device config.

e.g. lfssize 0x80000 for the max 512 kbyte FS.

e.g. lfssize 0x18000 for a 96 kbyte FS.

lfsunmount

lfsmount

lfsformat - format the current LFS

lfsformat 0xnnnn - configure the size and format the LFS

The files in the LFS can be managed from the webapp.
