Of course you can store both hardware (.sof) and software (.elf) into EPCS, then boot from EPCS. You can even use on-chip ROM to store some software images.

To do that, you must add a EPCS controller in your SOPC system, let the reset address point to it.

to download a EPCS bootloader patch, and follow the instructions it provides.

If any question, ask me. I have succeeded to do so.
