Hi, After seeing a number of customers struggling with this issue, I have written a detailed ApNote showing how to implement a multiple configuration system for Altera FPGAs. The example is a Cyclone III using Active Serial mode / EPCS (on a DE0 board), but it is easily translatable to any other Altera FPGA/board. It is not complex, but getting everything right from the documentation is not absolutely obvious. The ApNote and the design files are available at the top of the list at: http://www.alse-fr.com/apnotes.php Anyone spotting a discrepancy, please let me know. Hope this helps, Bert.

One thing, when I skimmed your post I presumed you were talking about configuring multiple devices from one flash chip, not multiple images for one device. Nial.

Dans son message pr�c�dent, Bert_Paris a �crit :> for Altera FPGAs.I don't assume it's going to be useful for Xilinx (or Actel or Lattice) users, since most of the work is about undesrtanding how to use the *Altera* Megafunction named "altremote_update"... Bert
