Is it possible to run NIOSV through SDRAM ?

Hello, I am developing a project where NIOS II needs to replaced with NIOSV processor. When my design was having NIOS II as CPU, I was running the software code through External SDRAM on the Cyclon...

Dear Himanshu,

Did you finally manage to run your program on the SDRAM? I also managed to include the SDRAM Controller Intel FPGA IP in Quartus 23.1. Compilation goes well but, like you, the basic "Hello World!" program gets stuck with SDRAM when it works fine with on-chip RAM. Yet, I can't run my project's software on the on-chip memory because the required amount of RAM won't fit on the FPGA.

Also, I would be interested in seeing how you worked around the interface issue for the exported signals. I had to rewrite the conduit interface ports for each signal individually.

Finally, do you have any idea who I could contact at Intel's to provide me with a more compatible version of the SDRAM Controller IP? I tried to contact Intel's support, but I can't find any section related to FPGAs. Probably, I looked in the wrong place...

Thanks in advance for your help.

Looking forward to reading from you.

Best regards

Vincent
