Abstract
Embodiments are described for recovery, via a sideband management bus, of firmware of a device such as an FPGA (Field Programmable Gate Array) card installed within an IHS (Information Handling System). A remote access controller of the IHS generates a security key for the device and transmits it to the device. The remote access controller requests the device to report the current version of the firmware in use by the device. The response from the device is authenticated based on the security key. If the current firmware version reported by the device is consistent with the master firmware version, the device is halted and the current firmware of the device is replaced with the master firmware. The device is initialized based on the master firmware used to update the device firmware.
