Remote Update Mode
1
Stratix V remote system upgrade circuitry only supports remote update mode. In
remote update mode, Stratix V 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.
When a Stratix V device is first powered up in remote update mode, it loads the
factory configuration located at the start address of PGM[23..0] = 24'h000000 in the
EPCS and EPCQ devices. You must store your factory configuration image at this start
address.
The application image start address can be at any EPCS or EPCQ sector boundary.
Altera recommends using different sectors in the EPCS device for two images.
The factory image is user-designed and contains soft logic to perform the following:

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 Stratix V
device
Enable or disable the user watchdog timer and load its time-out value
Instruct the dedicated remote system upgrade circuitry to start a reconfiguration
cycle
