Generate programming file for multiple device chain (HDL and Nios code)

I have a board that has two Cyclone IV devices on it. Each Cyclone will have it's own unique HDL and embedded NIOS processor. My question is how do I generate the programming file for the serial co...

Do I assume you've captured a design implementing a 'Multi-Device AS Configuration' scheme, as found in the configuration handbook - Figure 8-3? Page 8-13.

Whilst this is designed to configure multiple devices from a single configuration device, I'm not sure how you can (easily) retrieve two separate software images for your two Nios' in two separate FPGAs. I don't think it's going to be as easy as adding a second set of .sof & .elf files to the config device. There's quite an amount of arbitration to consider to prevent both devices accessing the configuration device at the same time.

Like I say, it can be done. Let me know whether I've interpreted your question correctly.
