Detailed Description

Function definitions for FBS system library, TFFS partitions.

Author:

D.L. Wood

These implementations are meant to work with a real TFFS file system and SIB EEPROM banks.

Function Documentation

unsigned int FILE_sysTffsCheck

(

int

drv

)

Check consistency of a TFFS partition.

Parameters:

drv

The TFFS drive number for the bank to check.

Returns:

A FILE MSG code.

Runs the DOSFS chkdsk utility on the requested TFFS partition. Only the status is checked; no repairs to the partition file system are attempted.

unsigned int FILE_sysTffsFormat	(	int	drv,
		unsigned int	offset
	)

Format a TFFS partition.

Parameters:

	drv	The TFFS drive number for the bank to format.
	offset	The offset in bytes from the bank base address at which the TFFS/FTL formatting should begin.

Returns:

A FILE MSG code.

Formats a TFFS file system for a raw TFFS non-volatile memory bank. Both the TFFS/FTL layer and the DOSFS layer are written to the media. The offset parameter allows a portion of a media memory bank to be used by boot software.

References FILE_PATH_STR_SIZE, FILE_PATH_STR_SIZE_USR, FILE_SYS_MAX_FILES, and TFFS_NUM_DIR.

unsigned int FILE_sysTffsMount

(

int

drv

)

Mount a TFFS partition.

Parameters:

drv

The TFFS drive number for the bank to format.

Returns:

A FILE MSG code.

Mounts a TFFS/DOSFS filesytem for use. The non-volatile memory bank must have previously been formatted with both the TFFS and DOSFS layers.

References FILE_SYS_MAX_FILES.

unsigned int FILE_sysTffsRepair

(

int

drv

)

Attempt to repair a bad TFFS partition.

Parameters:

drv

The TFFS drive number for the bank to repair.

Returns:

A FILE MSG code.

Runs the DOSFS chkdsk utility on the requested TFFS partition. If an error is found by the utility, repairs to the partition file system are attempted.
