Configuration Images

Configuration Images
Each Cyclone V device in your system requires one factory image. The factory image is a user-defined
configuration image that contains logic to perform the following:
Processes errors based on the status provided by the dedicated remote system upgrade circuitry.
Communicates with the remote host, receives new application images, and stores the images in the local
non-volatile memory device.
Determines the application image to load into the Cyclone V device.
Enables or disables the user watchdog timer and loads its time-out value.
Instructs the dedicated remote system upgrade circuitry to start a reconfiguration cycle.
You can also create one or more application images for the device. An application image contains selected
functionalities to be implemented in the target device.
Store the images at the following locations in the EPCS or EPCQ devices:
Factory configuration image—
Application configuration image—any sector boundary. Altera recommends that you store only one
image at one sector boundary.
