In the Intel® Quartus® Prime Pro Edition software version 20.3, when using the Configuration via Protocol (CvP) scheme on Intel® Stratix® 10 or Intel® Agilex™ devices, you may see this error when loading a core.rbf image after previously attempting to load a truncated core.rbf image.


To work around this problem, power cycle the system before reloading another complete core.rbf image.

This problem is scheduled to be fixed in a future release of the Intel® Quartus® Prime Pro Edition software.
