Remote system upgrade only supports single-device configuration.
When using remote system upgrade in Cyclone III devices, you must set the mode
select pins (MSEL [3.0]) to the AS or AP configuration scheme. When using remote
system upgrade in Cyclone III LS devices, you must set MSEL [3..0] to the AS
configuration scheme. The MSEL pin setting in remote system upgrade mode is the
same as standard configuration mode. Standard configuration mode refers to normal
Cyclone III device family configuration mode with no support for remote system
upgrades, and the remote system upgrade circuitry is disabled. When using remote
system upgrade in Cyclone III device family, you must enable the remote update
mode option setting in the Quartus II software. For more information, refer to
“Enabling Remote Update” on page
