Flash File System

MDK-Professional includes a Flash File System that allows your embedded applications to create, save, read, and modify files in standard storage devices such as ROM, RAM, Flash ROM, and SD/MMC/SDHC Memory Cards.

Features

• Standard ANSI C File I/O application interface
• NOR and NAND Flash Support
• RAM, ROM, and SD/MMC/SDHC Memory Cards
• Windows compatible FAT12, FAT16, and FAT32 formats
  (including sub-folders and long file names)
• SD/MMC card file-caching delivers high-speed read/write access
• Reentrant and thread-safe operation
• Simultaneous access to multiple storage devices
• Dialog-based setup using µVision Configuration Wizard
• On-chip Flash and external memory interfaces supported for numerous ARM-based devices
• Full documentation and SD/MMC/SDHC example projects are provided
• See the full list of Flash File System features

Many ARM-based microcontrollers have a practical requirement for a standard file system. With the Flash File System you can implement new features in embedded applications such as data logging, storing program state during standby modes, or storing firmware upgrades.
