Olivier Martin	2251b0267d	libraries/fs: Added logic to transparently sync written file ... fflush() does not do anything in mbed library. The only time the file was flushed was when it was closed. For some applications (eg: data logger), files are never closed. It means when the power went off all the written data were lost. Actually, they were not lost; they were written into the non-volatile storage. But the file header was not aware of these new data (its file information such as file size were not updated). There is no easy way to retarget fflush() for mbed. So, the workaround is to fflush (eg: 'sync' in the ChaN terminology) periodically while writting new data. The frequency can be changed by the user into ffconf.h. By default, the updated file will be synced for every new sector (generally for every 512 bytes). Another available option is to sync for every new cluster (in my use case, the cluster was 8 sectors long).	2014-02-21 09:57:23 +00:00

Adam Green	5e4439bb19	fs: Silence GCC signed/unsigned warnings ... The SDFileSystem class contained a few routines which compared a signed integer loop index to an unsigned integer length/size. I switched the loop index to be uint32_t as well.	2013-08-19 22:53:49 -07:00
