A method of operating a storage device may include establishing a connection between a host and the storage device, detecting a crash of the storage device, suspending, based on detecting the crash, processing commands from the host through the connection, recovering from the crash of the storage device, and resuming, based on recovering from the crash, processing commands from the host through the connection. The method may further include notifying the host of the crash based on detecting the crash of the storage device. Notifying the host may include sending an asynchronous event notification to the host through the connection. Notifying the host may include asserting a controller status indicator. The method may further include receiving a reset from the host, and resetting a storage interface based on receiving the reset from the host. The method may further include maintaining the connection through a communication interlace.

Systems, methods, and apparatus for crash recovery in storage devices

Embodiments of the inventive concept include a boot loader update firmware (), a system and method for producing the boot loader update firmware (), and a method for using the boot loader update firmware () to update a boot loader module () in a device (). The boot loader update firmware () can include logic () to install firmware () in non-volatile memory (). The firmware () can include a binary image () of the updated boot loader module (). When the device () is rebooted, the firmware () is activated, which can then copy the binary image) into non-volatile memory (). When the device () is rebooted again, the updated boot loader module () is activated.
