Chapter 9: Configuration, Design Security, and Remote System Upgrades in the Cyclone III Device Family
Remote System Upgrade
© December 2009

Altera Corporation
After power up or a configuration error, the factory configuration logic writes the
remote system upgrade control register to specify the address of the application
configuration to be loaded. The factory configuration also specifies whether or not to
enable the user watchdog timer for the application configuration and, if enabled,
specifies the timer setting.
Only valid application configurations designed for remote update mode include the
logic to reset the timer in user mode. For more information about the user watchdog
timer, refer to
If there is an error while loading the application configuration, the remote system
upgrade status register is written by the dedicated remote system upgrade circuitry of
the Cyclone III device family, specifying the cause of the reconfiguration.
The following actions cause the remote system upgrade status register to be written:
■
■
■
■
Cyclone III device family automatically load the factory configuration located at
address boot_address[23:0] = 24'b0 for the AS configuration scheme, and
default address boot_address[23:0] = 24'h010000 (or the updated address if the default
address is changed) for the AP configuration scheme. This user-designed factory
configuration reads the remote system upgrade status register to determine the reason
for reconfiguration. Then the factory configuration takes the appropriate error
recovery steps and writes to the remote system upgrade control register to determine
the next application configuration to be loaded.
When Cyclone III device family successfully load the application configuration, the
devices enter user mode. In user mode, the soft logic (Nios II processor or state
machine and the remote communication interface) assists the Cyclone III device
family in determining when a remote system update is arriving. When a remote
system update arrives, 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, determines the valid application configuration to load, writes the remote
system upgrade control register accordingly, and starts system reconfiguration.
