Flash filesystems

The QNX Neutrino flash filesystem drivers implement a POSIX-compatible filesystem on NOR flash memory devices.

The flash filesystem drivers are standalone executables that contain both the flash filesystem code and the flash device code. There are versions of the flash filesystem driver for different embedded systems hardware as well as PCMCIA memory cards.

The naming convention for the drivers is devf-system, where system describes the embedded system. For information about these drivers, see the devf-* entries in the Utilities Reference.
