Hello,

Unfortunately, ST doesn't provide LittleFS implementation. You may need to look for some implementations on the internet.

See the examples provided by @hans86 in this thread based on STM32H743 device.

That GitHub page says, "Detailed documentation (or at least as much detail as is currently available) can be found in the comments in lfs.h." - so have you looked at that?

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

@Andrew Neil there is documentation about how their functions works, not about interfacing between stm32h7 memory.

Why do you want any filesystem at all? It is easier just to include a file or few files into the image, like the "filesystem" used in the http server examples; or burn them into free space on the flash at known addresses.
