Extensibility

The file system service supports a straightforward and simple approach to
the insertion of additional or replacement drivers, to support different file
systems (FSDs) to interpret the media attached to new or existing physical
interfaces (PIDs).
New device drivers for insertion into the FSS must conform to either the
FSD or PID design documents supplied with VisualDSP++ 5.0:
Blackfin\docs\drivers\fsd\Generic_FSD_Design_Document.pdf,
Blackfin\docs\drivers\pid\Generic_PID_Design_Document.pdf,
These documents detail how the drivers interface with the other compo-
nents of the file system service framework.
Once created, the driver is directly available for incorporation within the
FSS. All that is required is to declare an
(and accompanying configuration table if required) and register it with the
FSS via the
ADI_FSS_CMD_ADD_DRIVER
{ ADI_FSS_CMD_ADD_DRIVER,(void*)&<Device-Def-Structure> },

Examples
Included with VisualDSP++ 5.0 are some examples to demonstrate how
the FSS is configured and how it can be used. As examples, their scope of
operation has been purposely limited; please employ caution when using
them as a basis for your own applications. The examples described in this
section are all specific to the ADSP-BF548 EZ-KIT Lite development
