Hello,

All the files you listed are within the working directory.

Before I just had "Option 1" selected at the debugging options. I also enabled the EMIF On-chip debug port, and the the above warnings went away when linking to device and I'm able to create memory interface connection, but I got a guaranteed read failure. Now Quartus crashes whenever I'm trying to link device to project.

Correct me if I'm wrong, but from my understanding, on-chip debug port is not needed for the EMIF toolkit itself to work, but for access to EMIF calibration through user logic (https://www.intel.com/content/www/us/en/docs/programmable/683841/17-0/on-chip-debug-port-for-uniphy-based-emif-ip.html) and "Option 1" is what you're referring to.

Are there any other possibilities for getting these problems?

Regards,

Yiannis
