Altera Corporation
You can enable or disable remote update for Cyclone III device family in the
Quartus II software before design compilation (in the Compiler Settings menu). To
enable remote update in the compiler settings of the project, perform the following
steps in the Quartus II software:
1. On the Assignments menu, click Device. The Settings dialog box appears.
2. Click Device and Pin Options. The Device and Pin Options dialog box appears.
3. Click the Configuration tab.
4. From the Configuration Mode list, select Remote.
5. Click OK.
6. In the Settings dialog box, click OK.
Configuration Image Types
When using remote system upgrade, Cyclone III device family configuration
bitstreams are classified as factory configuration images or application configuration
images. An image, also referred to as a configuration, is a design loaded into the
device that performs certain user-defined functions. Each device in your system
requires one factory image with the addition of one or more application images. The
factory image is a user-defined fall-back, or safe, configuration and is responsible for
administering remote updates with dedicated circuitry. Application images
implement user-defined functionality in the target Cyclone III device family. You can
include the default application image functionality in the factory image.
Overview
In remote update mode, the Cyclone III device family loads 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 can also contain application logic.
When used with configuration memory, remote update mode allows an application
configuration to start at any flash sector boundary. Additionally, the remote update
mode features a user watchdog timer that can detect functional errors in an
application configuration.
Remote Update Mode
When a Cyclone III device family is first powered up in remote update in the AS
configuration scheme, it loads the factory configuration located at address
boot_address[23:0] = 24b'0. Altera recommends storing the factory
configuration image for your system at boot address 24b'0 when using the AS
configuration scheme. A factory configuration image is a bitstream for
Cyclone III device family in your system that is programmed during production and
is the fall-back image when an error occurs. This image is stored in non-volatile
memory and is never updated or modified using remote access. This corresponds to
the start address location 0x000000 in the serial configuration device.
