A littlefs filesystem can be still be accessed on a PC over USB MSC using the
|
||||
`littlefs FUSE driver`_. Note that you must specify both the ``--block_size``
|
||||
and ``--block_count`` options to override the defaults. For example (after
|
||||
building the littlefs-fuse executable)::
|
||||
|
||||
$ ./lfs --block_size=4096 --block_count=512 -o allow_other /dev/sdb1 mnt
|
||||
|
||||
This will allow the board's littlefs filesystem to be accessed at the ``mnt``
|
||||
directory. To get the correct values of ``block_size`` and ``block_count`` use::
|
||||
|
||||
import pyb
|
||||
f = pyb.Flash(start=0)
|
||||
f.ioctl(1, 1) # initialise flash in littlefs raw-block mode
|
||||
block_count = f.ioctl(4, 0)
|
||||
block_size = f.ioctl(5, 0)
