Description
While running Hard Processor System (HPS) based Remote System Update on Agilex™ 7 SoC FPGAs, you may see the above message as a result of running the ‘rsu list’ command from the HPS. This is because the U-Boot detects a mismatched magic number due to an incompatible version of DCMF found on the attached flash device.
Resolution
To work around this problem, update the DCMF to version 20.3 to allow RSU to function correctly if using RSU features with versions of Quartus® Prime Pro Edition Software earlier than version 20.3
