Zilog File System

User Manual

Zilog File System Configuration

The Zilog File System is configured according to your requirements. The Zilog File Sys-

tem configuration file is located in the following path:

<ZDS II Installed directory>\Program Files\Zilog\

ZDSII_eZ80Acclaim!_A.B.C\ZTP\ZTPX.Y.Z_Lib\RZK\Conf

For internal and external Flash volumes, the Zilog File System requires equal-sized blocks

to store files and directories. If block sizes are unequal, the behavior of the Zilog File Sys-

tem is unknown. The driver must be capable of handling the logical block sizes for read-

ing/writing/erasing operations. Table 3 lists the logical block sizes for the sample Flash

drivers provided with the RZK release.

Zilog File System Macro Configuration

The Zilog File System provides macros for the configuration of different volumes and the

behavior of the File System. These macros, described in Table 4, are present in the

ZFS_Conf.c file, which is located in the following filepath:

<ZDS II Installed directory>\Program Files\Zilog\

ZDSII_eZ80Acclaim!_A.B.C\ZTP\ZTPX.Y.Z_Lib\RZK\Conf

You must provide the correct values of the macros and the volume configuration; other-

wise, the behavior of the Zilog File System is not defined.
