This error can occur as a result of the address width for the targeted DDR4 part changing between releases. Only the following DDR4 RDIMM parts are impacted:


  • MTA18ASF1G72PZ-2G1
  • MTA36ASF2G72PZ-2G1
  • MTA18ADF1G72PZ-2G1

Solution

If this error message is seen and you are targeting one of the impacted DDR4 RDIMM parts, then please regenerate the DDR4 IP from scratch in the new version of Vivado to resolve the issue.
