Recovery Mechanism for Embedded Device

Abstract

A device can be recovered by detecting a recovery event in a device having read-only and read-write memory partitions; selecting a set of recovery instructions stored in the device's read-only memory partition; booting the device based on the selected set of recovery instructions; and restoring a set of operating instructions in the device's read-write memory partition based on the set of recovery instructions. Detecting a recovery event further can comprise detecting a predetermined number of consecutive unsuccessful boot operations. Alternatively, detecting a recovery event further can comprise receiving from a user a command to execute a recovery operation. Further, a value in a non-volatile memory can be set to identify the read-only partition storing the set of recovery instructions as a boot partition. Additionally, restoring a set of operating instructions further can comprise replacing the set of operating instructions with at least a portion of the set of recovery instructions.
