Unable to establish a connection because no memory interface targets exist on the linked device

Hi, Can you check whether you had provided clock to pll_refclk pin and release the global_reset pin ? Thanks. Is this issue occurs on Intel FPGA dev kit board or your own board ? Regards, Deshi

Hi, global_reset_n pin is the control signal for EMIF IP reset function. What I am saying is have you release EMIF IP from reset stage by setting global_reset_n pin to high ? The other thing that I suspect is how many EMIF IP interfaces that you have in your design ? It's recommend to have EMIF toolkit to interact with one EMIF IP interface only. So, you can try to reduce your design complexity till having one EMIF toolkit to interact with one EMIF IP and nothing else in your Quartus design. Another thing is EMIF toolkit is relying on JTAG connection to interact with EMIF IP. "Device has different visible SLD agents" error seems to indicate there are multiple JTAG connection in either your board or in Quartus design that confuse the EMIF toolkit. Thanks. Regards, dlim
