Hi,

What's the Quartus version you're using?

Please use Q23.4 Pro onwards.

 

Regards,

Rong

    Hi Rong,

    We have tried Quartus Pro 24.3 and 24.1, both newer than 23.4. The CXL design example fails to bring up the device on both Quartus versions.

      You may need to put two DDR4-2666 DIMM memory onto the dev kit.
