1. A control device, comprising:
a first storage device in which rewrite of stored data is allowed;
a second storage device including
a limited storage area in which rewrite of stored data is prevented, and
a non-limited storage area in which rewrite of stored data is allowed; and
a processor configured to
execute activation processing to start control processing for a device to be controlled, the activation processing being based on the data stored in the limited storage area of the second storage device without being based on the data stored in the first storage device,
execute the control processing based on the data stored in the first storage device and the data stored in the second storage device while rewriting the data stored in the first storage device,
store a memory image relating to the first storage device at a point of time, at which the activation processing is terminated, in the non-limited storage area of the second storage device, and
start the control processing from the point of time, at which the activation processing is terminated, after loading the memory image stored in the non-limited storage area of the second storage device in the first storage device in the activation processing of the control processing.
