Why do I see a [Designutils 20-1280] message when opening a design in the Vivado elaboration mode?
This error can be safely ignored. It is a false alarm and has no impact on core functionality.
The error occurs when Vivado fails to detect the XDC of the sub-core used in the MIPI CSI-2 Receiver Subsystem.
The MIPI CSI-2 Receiver Subsystem can be synthesized and implemented as normal.
