After power up or a configuration error, the factory configuration image is loaded
automatically. The system then decides to switch to the application configuration
image or to stay in the factory configuration image. After the system decides to switch
to an application configuration image, a reconfiguration is initiated through the
remote system upgrade circuitry. In the application configuration image, the system
may revert back to factory configuration image after the following reconfiguration
trigger conditions are met:

After the factory configuration image is re-loaded, the user-designed factory
configuration can read the remote system upgrade status register to determine the
reason for the reconfiguration. The factory configuration then takes the appropriate
error recovery steps and writes to the remote system upgrade control register to
determine the next application configuration to be loaded.
Whenever the application configuration image is successfully loaded, the soft logic
(Nios II processor or state machine and the remote communication interface)
determine when the remote system update is arriving. When this occurs, the soft logic
receives the incoming data, writes it to the configuration memory device, and triggers
the device to load the factory configuration. The factory configuration reads the
remote system upgrade status register and control register, determines the valid
application configuration to load, writes the remote system upgrade control register
accordingly, and initiates system reconfiguration.
Remote System Upgrade Using EPCQ 256
When you are using EPCQ 256, ensure that the application image address granularity
is 32’h00000100. The .rbf size for your application image is 76,500 bytes longer than
the numbers listed in
requirement into consideration when you try to fit multiple application images in the
EPCQ 256 device.
If you are not using Quartus II software or SRunner software for EPCQ 256
programming, put your EPCQ 256 device into four-byte addressing mode before you
program and configure your device.
This section describes the implementation of the Stratix V dedicated remote system
upgrades circuitry. The remote system upgrade circuitry is implemented in hard logic.
This dedicated circuitry interfaces with the user-defined factory and application
configurations implemented in the Stratix V device logic array to provide the
complete remote configuration solution. The remote system upgrade circuitry
contains the remote system upgrade registers, a watchdog timer, and a state machine
that controls those components.
