Abstract: The FCM provides a glueless interface to parallel-bus NAND Flash E2PROM devices within MPC837x microprocessors. This paper analyses the transmission mechanism of FCM mode and the drive architectures of TrueFFS in VxWorks based on VxWorks and MPC8379E embedded system developing platform, introduces the drive design of NAND Flash under FCM interface and provides the method to realize TrueFFS drive interface. FCM interface drive can be easily embedded in other embedded systems based on hierarchical drive design.
