Abstract
An apparatus, system, and method are disclosed for providing a backup configuration image to a programmable hardware device. A receiving module receives a configuration file for the programmable hardware device. The configuration file comprises a synchronization key and a configuration image. An image write module writes the configuration image to a first section of a memory device. The memory device comprises the first section and a second section that stores a synchronization key and a backup configuration image. A key write module writes at least a portion of the synchronization key to the first section of the memory device in response to the image write module completing the write of the configuration image to the first section of the memory device. During a loading cycle, the programmable hardware device searches the memory device for a valid synchronization key, and loads the configuration image that corresponds to the valid synchronization key.
