Abstract
Systems, methods, and computer software for operating a device can be used to operate the device in multiple modes. The device can be operated in a first operating mode adapted for processing data, in which a first processor executes a driver for a nonvolatile memory and a second processor performs processing of data stored in files on the nonvolatile memory. An instruction can be received to switch the device to a second operating mode adapted for reading and/or writing files from or to the nonvolatile memory. The driver for the nonvolatile memory can be switched from the first processor to the second processor in response to the instruction, and the driver for the nonvolatile memory can be executed on the second processor after performing the switch. A communications driver can be executed on the first processor in response to the instruction to switch the device to the second operating mode.
