NFDisk-related Processing
The SH4 CPU & .NET installed IPC series has onboard NAND Flash ROM (hereafter abbreviated NF)
mounted as NFDisk to be accessible from within Windows CE .NET 4.2.
The system uses part of NFDisk to save the registry (REG3.bin) and ObjectStore files
(\NFDisk\Update).
NFDisk is used for ObjectStore and registry files as follows.
CAUTION
NFDisk stores data on Compact Flash media. Accordingly, there is a limit to the number of times
data can be rewritten. Refer to the hardware manual for details.
ObjectStore files
Object store Backup and Restore
Restore ObjectStore
To update the standard module in NK.BIN, store the update module in the \NFDisk\Update directory.
At startup, this series copies the content of the \NFDisk\Update directory to the root directory and the
content of the \NFDisk\Update\Windows to the Windows directory.
For example, when updating the serial driver (serial.dll), this series copies the new serial driver
(serial.dll) to the \NFDisk\Update\Windows directory to copy the new serial driver to the Windows
directory at startup.
This completes the updating process of the serial driver.
Not to restore ObjectStore
Delete the contents of the \NFDisk\Update directory or execute a forced reset.
