Abstract
An updating method for firmware that is stored as a file in an image forming apparatus that includes a file system that has a journaling function. The method comprises determining whether an update for the firmware is instructed, and determining to update the firmware when it is determined that the update is instructed; determining whether firmware for the update is stored in a storing unit when it is determined to update the firmware, and disabling the journaling function when the firmware for the update is stored in the storing unit; and updating the firmware by use of the firmware for the update in a state in which the journaling function is disabled.
Claims11
A method for updating firmware stored as a file in an image forming apparatus that includes a file system that has a journaling function, the method comprising the steps of:
- determining whether an update of the firmware is instructed, and determining to update the firmware when it is determined that the update is instructed;
- determining whether an updating firmware is stored in a storing unit when it is determined to update the firmware, and disabling the journaling function when the updating firmware is stored in the storing unit;
- and
- updating the firmware by use of the updating firmware in a state in which the journaling function is disabled.
An image forming apparatus that comprises a file system that includes a journaling function and is provided with a processor to function as:
- a determining unit configured to determine whether an update of the firmware stored as a file is instructed, and determine to update the firmware when it is determined that the update is instructed;
- a disabling unit configured to determine whether an updating firmware is stored in a storing unit when it is determined to update the firmware, and disable the journaling function when the updating firmware is stored in the storing unit;
- and
- an updating unit configured to update the firmware by use of the updating firmware in a state in which the journaling function is disabled.
A non-transitory storage medium on which is stored a computer program for making a computer execute a method for updating firmware stored as a file in an image forming apparatus that includes a file system that has a journaling function, the method comprising:
- determining whether an update of the firmware is instructed, and determining to update the firmware when it is determined that the update is instructed;
- determining whether an updating firmware is stored in a storing unit when it is determined to update the firmware, and disabling the journaling function when the updating firmware is stored in the storing unit;
- and
- updating the firmware by use of the updating firmware in a state in which the journaling function is disabled.
