Honored ContributorI have successfully implemented a system which uses remote update with active serial configuration.
Altera's documentation definitely seems lacking in this area. I got it working based on AN429 and the Cyclone III handbook. A scope on the SPI lines to the memory and other configuration related signals was also a big help. In the end, I created my own SPI component and software for writing and reading to the flash memory. The tricky part was then figuring out how to control the remote update hardware to trigger the reconfig to the application image.
