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.
