The MSEL pin setting in the remote system upgrade mode is the same as the standard
configuration mode. Standard configuration mode refers to normal Cyclone IV device
configuration mode with no support for remote system upgrades (the remote system
upgrade circuitry is disabled). When using remote system upgrade in Cyclone IV
devices, you must enable the remote update mode option setting in the Quartus II
software.
Enabling Remote Update
You can enable or disable remote update for Cyclone IV devices 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:
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 IV device 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 or with 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 the dedicated circuitry. Application images implement
user-defined functionality in the target Cyclone IV device. You can include the default
application image functionality in the factory image.
