Remote system upgrade has one mode of operation: remote update mode. The remote
update mode allows you to determine the functionality of your system upon
power-up and offers different features.
In remote update mode, Stratix III devices load the factory configuration image upon
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 logics.
When used with serial configuration devices, the remote update mode allows an
application configuration to start at any flash sector boundary. This translates to a
maximum of 128 pages in the EPCS64 device and 32 pages in the EPCS16 device,
where the minimum size of each page is 512 KBits. Additionally, the remote update
mode features a user watchdog timer that determines the validity of an application
configuration.
When a Stratix III 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). You
should 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 configuration image is user-designed and contains soft logic to do the
