3.6 Non-volatile Storage
Nordic ID Morphic comes equipped with a persistent storage device opening the way for business
applications to store data in files on the device, for example, when data colleting is being done in
the area being out of the reach of wireless communication. Especially, in the cases when the
persistence of the data is a preferred quality.
By default, the whole storage is allocated for one file system partition using ‘Flash’ as a logical
drive name, meaning in practice that the partition is represented as a ‘Flash’ directory off the root
of the file system. You cannot replace the ‘Flash’ name with another although you repartition the
volume. ‘Flash’ remains the directory (folder) name for the first partition. If there is more than one
partition on the storage device, the folder name of the second partition is ‘Flash2’; the third would
be ‘Flash3’, and so on.
If your application needs the persistent storage, then repartitioning the volume is recommended
because a Nordic ID Customizer system uses the first partition to bring update, upgrade, bug fix,
and customizing patches to the system through *.pak files stored in the ‘Flash’ folder. In case of
repartitioning the volume, it is reasonable to reallocate two times the size of the Windows CE
system image for the first partition, that is, about 30 - 40 megabytes (,or at least 20Mbytes), so that
your application could use the persistent storage freely within its own partition(s). In the Control
Panel there is an applet called ‘Storage Manager’ with which you can repartition the persistent
storage.
Note
that you can create only FAT file system partitions on the storage.
The storage in a nutshell
Storage technology
NAND Flash
Storage capacity
128 Megabytes
Note
that the ‘Storage Manager’ (don’t confuse
this with the Control Panel applet being the same
by name) allocates half a megabyte for managing
the device. In addition, each partition takes about
half a megabyte from the allocated capacity to
maintaining of the partition table(s).
File systems available
FAT
Sector size
512 Bytes
Logical name of the device
‘DSK1:’
Logical drive(s) as folder(s)
off the root in the file
systems hierarchy
‘Flash’, ‘Flash2’,
‘Flash3’, and so
on

3.7 Control Panel
Control panel is a collection of applets to access the settings of different system properties; to
configure those properties; to change their performance characteristics; to enable and disable
them, among others. The control panel is one channel to manage the properties of the Nordic ID
Morphic. It may not be the most convenient means to do that, and it is worth considering whether
