* altos: Stick a mutex around FAT operationsKeith Packard2013-04-12
| | | | | | This allows the command line and logging operations to occur safely in parallel Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add a FAT test that re-writes the same file multiple timesKeith Packard2013-04-01
| | | | | | This caught a bunch of FAT cluster chain allocation bugs. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Unmount file system after each testing pass in ao_fat_testKeith Packard2013-03-31
| | | | | | Otherwise, we use stale data and 'bad things' happen. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add FAT32 support. And lots more testing.Keith Packard2013-03-29
| | | | | | | | Generalizes the FAT code to deal with either 16-bit or 32-bit versions. The testing code now runs over a variety of disk images to check for compatibility on all of them. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add a simple cache for the FAT position->cluster computationKeith Packard2013-03-28
| | | | | | | This improves read/write performance with large files by not re-walking the cluster chain for every operation Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Clean up fat driver API. Improve fat testKeith Packard2013-03-28
| | | | | | | | Make FAT api provide reasonable error return values, change the tests to write and then read a pile of files, checking that the contents are correct (using md5sum). Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add SDCARD and FAT16 filesystem supportKeith Packard2013-03-27
This adds a fairly primitive FAT16 file system implementation along with support for SD cards. Signed-off-by: Keith Packard <keithp@keithp.com>
