It seems that extmod/vfs.h should be included in pyblittlefs.c if MICROPY_VFS_LITTLEFS is true.
Thanks, now fixed! |

Some of the commits here were merged to master (the ones related to a refactoring of the drivers/memory/spiflash driver), and this PR was rebased and force-pushed. |

When I go to https://github.com/geky/littlefs in my web browser it automatically redirects to https://github.com/ARMmbed/littlefs ?

After I made this PR the littlefs project moved to the ARMmbed organisation. I'll update the link.

I'm probably missing something obvious, but a) the functionality of strspn and strcspn appears to be identical, and b) neither of these functions actually seem to be used?
EDIT: Ooops, I finally spotted that one is doing != NULL and the other is doing == NULL 😊

They are used within littlefs itself. The linker will complain if they are not defined.
As a test/example, external SPI flash is mounted automatically on boot. The configuration for this is defined at the top of pyblittlefs.c.
Runs on unix coverage and stm32.
This needs to be enabled by a particular board when it wants to have a native littlefs filesystem.

For reference, I've got a rebased copy of this with some minor additional patches available at: https://github.com/andrewleech/micropython/tree/littlefs |

Chatting about this on slack, "Scott (tannewt)" brought up GhostFat from https://github.com/lancaster-university/codal-core/blob/master/source/drivers/GhostFAT.cpp as a possible avenue for maintaining mass storage support with littlefs etc in a safer way. It' implements fake block interface for mass storage, pretending to be fat. This looks to be very similar too: https://github.com/mmoskal/uf2-stm32f/blob/master/ghostfat.c |

This PR is work-in-progress to add littlefs as a new component for a new VFS. Currently works on unix coverage build and stm32 (pyboard etc). See tests/extmod/vfs_little.py for a demo/test, and ports/stm32/pyblittlefs.c for stm32 configuration.
Still to do:
