Note: Quartus® Prime Pro Edition version 25.1 is the first official release which supports RSU for Agilex™ 5 devices. Since the QSPI ownership selection feature is supported starting with the 25.1 release, Altera recommends not using bitstreams generated before version 25.1 and bitstreams generated with 25.1 release and later together.
