A method of locating a starting point of a firmware image in a non-volatile memory unit may include checking each of a number of possible starting points within the non-volatile memory unit until a code space signature is located that indicates the starting point of the firmware image. A system for implementing this method in a host device may include a non-volatile memory unit of the host device, and a boot module stored in the host device for execution by a processor, where the boot module is configured, when executed, to check each of a number of possible starting points for the firmware image within the non-volatile memory unit until a code space signature is located that indicates the starting point of the firmware image. A method of locating where in a non-volatile memory unit an incoming firmware image can be stored may include, on receipt of a the incoming firmware image, attempting to erase at least one block of the non-volatile memory unit and storing the incoming firmware image in the non-volatile memory unit where the attempt to erase succeeds. A system for implementing this method in a host device may include a processor of the host device for running an existing firmware image and a non-volatile memory unit of the host device, where the existing firmware image is configured, on receipt of a the incoming firmware image, to attempt erasure of at least one block of the non-volatile memory unit, and store the incoming firmware image in the non-volatile memory unit where the attempted erasure succeeds.
