Abstract
A processing device in a memory sub-system performs a reboot sequence in response to an occurrence of a power cycle event and determines whether a recovery signal is asserted from a host system via a side-band interface. Responsive to determining that the recovery signal is asserted, the processing device retrieves and loads a backup firmware image for the memory sub-system and booting the memory sub-system in a debug operational mode.
Claims20
A memory sub-system comprising:
- a memory device;
- a processing device, operatively coupled with the memory device, to perform operations comprising:
- performing a reboot sequence in response to an occurrence of a power cycle event;
- determining whether a recovery signal is asserted from a host system via a side-band interface;
- responsive to determining that the recovery signal is asserted, retrieving and loading a backup firmware image for the memory sub-system;
- and
- booting the memory sub-system in a debug operational mode using the backup firmware image.
A method comprising:
- performing a reboot sequence of a memory sub-system in response to an occurrence of a power cycle event;
- determining whether a recovery signal is asserted from a host system via a side-band interface;
- responsive to determining that the recovery signal is asserted, retrieving and loading a backup firmware image for the memory sub-system;
- and
- booting the memory sub-system in a debug operational mode using the backup firmware image.
A non-transitory computer-readable storage medium comprising instructions that, when executed by a processing device, cause the processing device to perform operations comprising:
- performing a reboot sequence of a memory sub-system in response to an occurrence of a power cycle event;
- determining whether a recovery signal is asserted from a host system via a side-band interface;
- responsive to determining that the recovery signal is asserted, retrieving and loading a backup firmware image for the memory sub-system;
- and
- booting the memory sub-system in a debug operational mode using the backup firmware image.
