Methods and apparatus for in-field mitigation of firmware failures

Abstract:

Methods, apparatus, systems and articles of manufacture for mitigating a firmware failure are disclosed. An example apparatus includes at least one hardware processor and first memory including instructions to be executed by the at least one hardware processor. The example apparatus further includes mask memory including a feature mask associated with a first firmware version, the feature mask identifying features of the first firmware version to be disabled. A platform firmware controller is to apply the first firmware version to the first memory for execution by the at least one processor, initialize the at least one processor using the feature mask, and in response to a detection of a failure, determine a first de-feature mask based on a second de-feature mask previously used by the at least one processor and the feature update mask; and initialize the processor using the first de-feature mask.
