Configuring Stratix II and Stratix II GX Devices

A serial configuration device can be programmed in-system by an
external microprocessor using SRunner. SRunner is a software driver
developed for embedded serial configuration device programming,
which can be easily customized to fit in different embedded systems.
SRunner is able to read a raw programming data (.rpd) file and write to
the serial configuration devices. The serial configuration device
programming time using SRunner is comparable to the programming
time with the Quartus II software.
For more information about SRunner, refer to AN 418: SRunner: An
Embedded Solution for Serial Configuration Device Programming and the
source code on the Altera web site at www.altera.com.
For more information on programming serial configuration devices,
refer to the Serial Configuration Devices (EPCS1, EPCS4, EPCS16, EPCS64,
and EPCS128) Data Sheet in the Configuration Handbook.
