lib_storage
Directory
As shown in Figure 2-6, the lib_storage directory contains the libraries for SBC mass
storage support. In order to standardize the interfaces and to keep confidentiality on
these modules embedded SCSI modules are delivered in library form (source code not
delivered).
SBC module is composed of the following libraries:
n
sbc.lib
This lib contains the common (not memory dependant) SBC functions.
n
sbc_df.lib
This lib contains the specific SBC functions for DataFlash support.
n
sbc_mmc.lib
This lib contains the specific SBC functions for MultiMediaCard support.
n
sbc_nf.lib
This lib contains the specific SBC functions for Nand Flash support.
n
sbc_smc.lib
This lib contains the specific SBC functions for SmartMediaCard support.
n
sbc_cf.lib
This lib contains the specific SBC functions for CompactFlash support.
Information on how to interface with those libraries is given in Section 2.3.
