Damien George f9dc644017 extmod: When including extmod headers, prefix path with extmod/. 2016-05-20 12:46:20 +01:00
Damien George bcd719ea3a extmod/fsusermount: In mount/mkfs, deregister VFS object on error.
Should fix issue #1947.

Paul Sokolovsky 1bb15ca427 extmod/fsusermount,vfs_fat: Nanbox cleanness. 2016-02-14 19:15:22 +02:00
Paul Sokolovsky e9be6a378c extmod/vfs_fat: Object-oriented encapsulation of FatFs VFS.
This implements OO interface based on existing fsusermount code and with
minimal changes to it, to serve as a proof of concept of OO interface.

Examle of usage:

bdev = RAMFS(48)
uos.VfsFat.mkfs(bdev)
vfs = uos.VfsFat(bdev, "/ramdisk")
f = vfs.open("foo", "w")
f.write("hello!")
f.close()

Damien George b33a770596 extmod/fsusermount: Support mounting of multiple block devices.
This patch adds support to fsusermount for multiple block devices
(instead of just one).  The maximum allowed is fixed at compile time by
the size of the fs_user_mount array accessed via MP_STATE_PORT, which
in turn is set by MICROPY_FATFS_VOLUMES.

With this patch, stmhal (which is still tightly coupled to fsusermount)
is also modified to support mounting multiple devices   And the flash and
SD card are now just two block devices that are mounted at start up if
they exist (and they have special native code to make them more
efficient).

Damien George c33ad60a67 extmod/fsusermount: Change block protocol to support ioctl method.
The new block protocol is:
- readblocks(self, n, buf)
- writeblocks(self, n, buf)
- ioctl(self, cmd, arg)

The new ioctl method handles the old sync and count methods, as well as
a new "get sector size" method.

The old protocol is still supported, and used if the device doesn't have
the ioctl method.

Paul Sokolovsky 3846fd56c1 extmod/fsusermount: Implement separate umount() function. 2016-02-10 00:51:47 +02:00
Paul Sokolovsky 5b85a86ce3 extmod/fsusermount: Introduce separate mkfs() function.
Per the previously discussed plan. mount() still stays backward-compatible,
and new mkfs() is rought and takes more args than needed. But is a step
in a forward direction.

Paul Sokolovsky 103fbaaf27 extmod/fsusermount: Common subexpression elimination.
Don't repeat MP_STATE_PORT(fs_user_mount), use local var.
