help
|
|
This option sets the FATFS configuration value _FS_LOCK.
|
|
The option _FS_LOCK switches file lock function to control duplicated file open
|
|
and illegal operation to open objects.
|
|
|
|
* 0: Disable file lock function. To avoid volume corruption, application
|
|
should avoid illegal open, remove and rename to the open objects.
|
|
|
|
* >0: Enable file lock function. The value defines how many files/sub-directories
|
|
can be opened simultaneously under file lock control.
|
|
|
|
Note that the file lock control is independent of re-entrancy.

help
|
|
This option sets FATFS configuration value _FS_TIMEOUT, scaled to milliseconds.
|
|
Sets the number of milliseconds FATFS will wait to acquire a mutex when
|
|
operating on an open file. For example, if one task is performing a lenghty
|
|
operation, another task will wait for the first task to release the lock,
|
|
and time out after amount of time set by this option.

bool "Use separate cache for each file"

|
|
help
|
|
This option affects FATFS configuration value _FS_TINY.
|
|
|
|
If this option is set, _FS_TINY is 0, and each open file has its own cache,
|
|
size of the cache is equal to the _MAX_SS variable (512 or 4096 bytes).
|
|
This option uses more RAM if more than 1 file is open, but needs less reads
|
|
and writes to the storage for some operations.
|
|
|
|
If this option is not set, _FS_TINY is 1, and single cache is used for
|
|
all open files, size is also equal to _MAX_SS variable. This reduces the
|
|
amount of heap used when multiple files are open, but increases the number
|
|
of read and write operations which FATFS needs to make.
