circuitry and cause the device to automatically revert to the factory image. The factory
image then performs error processing and recovery. The factory configuration is
written to the serial configuration device only once by the system manufacturer and
should not be remotely updated. On the other hand, application configurations may
be remotely updated in the system. Both images can begin system reconfiguration.
Remote system upgrade has only one mode of operation: remote update mode.
Remote update mode allows you to determine the functionality of your system after
power-up and offers different features.
In remote update mode, Arria II GX devices load the factory configuration image after
power up. The user-defined factory configuration determines which application
configuration is to be loaded and triggers a reconfiguration cycle. The factory
configuration may also contain application logic.
When used with serial configuration devices, remote update mode allows an
application configuration to start at any flash sector boundary. For example, this
translates to a maximum of 128 sectors in the EPCS64 device and 32 sectors in the
EPCS16 device. Altera recommends not using the same sector in the serial
configuration devices for two images. Additionally, remote update mode features a
user watchdog timer that determines the validity of an application configuration.
When an Arria II GX device is first powered up in remote update mode, it loads the
factory configuration located at page zero (page registers PGM[23:0] = 24'b0).
Always store the factory configuration image for your system at page address zero.
This corresponds to the start address location 0×000000 in the serial configuration
device.
The factory image is user-designed and contains soft logic to:

Process any errors based on status information from the dedicated remote system
upgrade circuitry
Communicate with the remote host and receive new application configurations
and store this new configuration data in the local non-volatile memory device
Determine which application configuration is to be loaded into the Arria II GX
device
Enable or disable the user watchdog timer and load its time-out value (optional)
Instruct the dedicated remote system upgrade circuitry to start a reconfiguration
cycle
