  • Patent number: 9092300
    Abstract: A peripheral device for an electronic device includes a memory configured to store at least an active firmware image and another firmware image, and circuitry configured to execute instructions provided in the firmware image. The circuitry receives, from a software application of the electronic device, commands and a firmware image included in the software application. The circuitry verifies the received firmware image file and writes the portions to a memory block different from a memory block at which the active firmware image is located. A command from the software application causes the peripheral device to specify the newly written firmware image as an active firmware image and to execute the newly active firmware image.

  • Publication number: 20140317318
    Abstract: An electronic device executes a software application that includes instructions for updating firmware of a peripheral device and one or more firmware images. The electronic executes the firmware update instructions to initiate the firmware update of the peripheral device and transfers a firmware image from the software application to the peripheral device according to a response from the peripheral device. The software application sends information to the peripheral device for verifying the transferred firmware image and causes the peripheral device to use the transferred firmware image upon successful verification.
