ABSTRACT:
Systems, methods, and computer-readable media provide for updating a firmware image during a debugging sequence using a firmware debugger application without re-flashing each updated firmware image on a non-volatile memory device. Embodiments include a debugger application operating on a host computer system and a debugger driver located within a firmware image undergoing the debugging sequence on a target computer system. The debugger application and debugger driver may communicate and transfer data between one another. Upon detecting an error in a firmware image, the debugger driver notifies the debugger application. The debugger application sends an updated firmware image to the debugger driver on the target computer system. The debugger driver loads the updated firmware image and passes control to an entry point of the updated firmware image for continued debugging from the new entry point.
