4. Memory Cards – FAT16 Format
The uDrive uses off the shelf standard SD/microSD
memory cards with up to 2Gb capacity. For any
FAT file related operations, before the memory
card can be used it must first
be formatted with FAT16
option. The formatting of
the card can be done on any
PC system with a card
reader.
appropriate
choose the FAT16 (or just FAT in some systems)
option when formatting.
The uDrive also supports high capacity HC
memory cards (4Gb and above). The available
capacity of SD-HC cards varies according to the
way the card is partitioned and the commands
used to access it.
The FAT partition is always first (if it exists) and can
be up to the maximum size permitted by FAT16.
Windows will format FAT16 up to 2Gb and the
Windows command prompt will format FAT16 up
to 4Gb.
For the RAW partition, byte reads and writes can
access 2^32 (i.e. 4gb) of the card, Sector reads and
writes can access 2^24 sectors (of 512 bytes, i.e.
8gb).
The total amount of the card usable is the sum of
the FAT and RAW partitions.
The GOLDELOX-DOS controller on the uDRIVE
module can be re-programmed with the latest
PmmC configuration for updates and future
proofing. The chip-level configuration is available
as a PmmC (Personality-module-micro-Code) file
and the programming must be performed over
the serial interface. All of the high level software
interface commands are part of the PmmC
configuration file so please check regularly for the
latest updates and enhancements.

It is recommended that the uDRIVE module be
socketed on the application board so that it can
be easily removed for PmmC programming. If the
module is to be permanently fixed and cannot be
removed then access must be provided for PmmC
programming on the application board. This is
referred to as “In Circuit Serial Programming”
(ICSP). Figure 3 provides a typical implementation
for the ICSP interface.
The PmmC file is programmed into the device
with the aid of “PmmC Loader”, a PC based
software tool. To provide a link between the PC
and the ICSP interface a USB to Serial converter is
required. A range of custom made micro-USB
devices such as the uUSB-MB5 and the uUSB-CE5
are available from 4D Systems. For further details
refer to 'Section 6: Development and Support
Tools'.
