Abstract
The present invention provides an embedded system and method for recovering the file system of flash memory when damage has occurred to the file system of the flash memory. The embedded system is equipped with NOR flash memory. The embedded system includes boot Programmable Read-Only Memory (PROM) and a Central Processing Unit (CPU). The boot PROM stores a normal state check value for a Cyclic Redundancy Check (CRC), and performs the recovery of the NOR flash memory if it is determined that a failure has occurred in the NOR flash memory through failure detection. The CPU is set such that it jumps to the boot PROM at the time of startup of the embedded system.
