Why is the Configuration via Protocol (CvP) Initialization or CvP Update not functioning in Intel Agilex® 7 devices?

Due to a problem in the Intel® Quartus® Prime Pro Edition Software version 21.2, performing CvP Initialization or CvP Update with Intel Agilex® 7 devices is not functioning properly. This is because the PCIe link is not able to enumerate properly after the periphery image is being loaded. For Intel Agilex 7 devices, the PCIe link can enumerate when loading the full image instead of periphery image. However, performing CvP Update will fail. Non CvP use case is not affected by this problem.

This problem is fixed starting with the Intel® Quartus® Prime Pro Edition Software version 21.3.
