Abstract
Techniques are described for managing firmware versions for a storage device. In one example, a storage device includes a memory and a controller. The controller is configured to execute a first version of a firmware, receive information for a second version of a firmware that is different from the first version, determine, based on the information for the second version of the firmware, whether the version of the second version of the firmware is stored in a system area of the memory, responsive to determining that the second version of the firmware is stored in the system area, load the second version of the firmware, responsive to determining that the second version of the firmware is not stored in the system area, store the second version of the firmware in the system area, update an active firmware index, and execute the second version of the firmware.
