HiWe want to implement a backup system with two or more POF file in one EPCS or flash without external host , when an unexpected issue occur in new firmware , our customer can load old version firmware without any development tools. Is that possible? We thought we can change the image load address of AS mode of FPGA, so it can load different firmware but I couldn't find how. We also found the solutions could need an addition MCU or MAXII. But we don't have enough space for addition MCU in our design. Thank you very much.
For newer FPGAs, you should consider to design the intended functionality around the Remote System Upgrade IP. Consult the Device Hardware Manuals for details.
