Hi Andy,

I don't think there's any Altera docs specifically detailing what you're after. However, I think it should be possible to generate 'factory' & 'application' FPGA images, each containing a Nios with a different reset vector corresponding to a different address in UFM.

This application note: remote system upgrade for max 10 fpga devices over uart with the nios ii processor (https://www.altera.com/en_us/pdfs/literature/an/an741.pdf) discusses something similar. It also details what manipulation is needed of the various binaries for programming and remote upgrades.

Note: it does discuss the use of an external FLASH device for holding the Nios image. The UFM is not big enough to hold a single user Nios image for larger applications. You're looking to put two Nios images in this space. So, you may need to consider an external flash device to hold these.

Cheers,

Alex
