FTP server and file system access can only be achieved with the pluggable flash
memory module. Access via FTP server can only take place via the Ethernet TCP/
IP interface.
Due to given requirements SBC uses its own file system. The SBC file system
is embedded in a FAT (PC compatible file system) framework to visualize the
restricted processes when used in a commercial SD card reader/writer with
standard PC tools. The SBC file system is named SBCNTFS.FFS.
Access to individual files in SBCNTFS.FFS is possible with a SBC-provided
software tool for PCs.
