Dave Hylands d368611ea6 Proposed fix for USB Mass Storage. 2014-10-01 22:52:02 +01:00
Damien George 1d7fb82f0a stmhal: Change 64-bit arithmetic to 32-bit for SD card block addressing.
By measuring SD card addresses in blocks and not bytes, one can get away
with using 32-bit numbers.

This patch also uses proper atomic lock/unlock around SD card
read/write, adds SD.info() function, and gives error code for failed
read/writes.

Damien George 04b9147e15 Add license header to (almost) all files.
Blanket wide to all .c and .h files.  Some files originating from ST are
difficult to deal with (license wise) so it was left out of those.

Also merged modpyb.h, modos.h, modstm.h and modtime.h in stmhal/.

Damien George 6d983539bc stmhal: Improve flash storage cache management.
Internal flash used for the filesystem is now written (from the cache)
only after a 5s delay, or when a file is closed, or when the drive is
unmounted from the host.  This delay means that multiple writes can
accumulate in the cache, and leads to less writes to the flash, making
it last longer.

It's implemented by a high-priority interrupt that takes care of flash
erase and write, and flushing the cache.

This is still only an interim solution for the flash filesystem.  It
eventually needs to be replaced with something that uses less RAM for
the cache, something that can use more of the flash, and something that
does proper wear levelling.

Dave Hylands e553ff2f75 Fix to allow usbd_msc_storage.c to compile when MICROPY_HW_HAS_SDCARD isn't defined. 2014-04-16 10:01:17 -07:00
Damien George 9699ea6a2f stmhal: Fix USB MSC so that it unmounts correctly on Mac OS X.
Mac OS X sends a SCSI command to remove the medium when it unmounts a
drive.  If this command is not honoured, then OS X will automatically
remount the drive, making it impossible to eject.  This patch disables
the USB MSC when the right SCSI command is sent.

Damien George 09d207785c stmhal: Unify naming of HW config; make SD detect configurable.
All board config macros now begin with MICROPY_HW_.

Renamed PYBv10 to PYBV10, since macros should be all uppercase.

Made SDCARD_DETECT configurable in mpconfigport.h, so that the SD
detect pin can be easily configured.

Damien George fb25c2d95f stmhal: USB CDC and MSC device work together. 2014-03-22 12:32:54 +00:00
Damien George 8913c04831 stmhal: Add support for USB MSC device.
This gives a functioning, independent MSC device.
