Abstract: Provided are techniques for restoring firmware. A first programmable hardware device determines that a second programmable hardware device needs a valid firmware image, retrieves a copy of the valid firmware image from an external memory, and sends the valid firmware image to the second programmable hardware device via a private communication link, wherein the private communication link enables private communication between the first programmable hardware device and the second programmable hardware device. The second programmable hardware device restores existing firmware using the valid firmware image.
