    Back to Rakesh

    I have a couple questions:

    1) Do you have a delay block on the reset going to the Nios (helps the core out of reset since the first few clocks out of the PLL most likely are not in perfect phase yet)?

    2) Is your PLL configured for the correct device (like what Joe98 found)?

    i derived my stuff from the Altera Nios2 cyclone design, full_featured. The sdram_pll on that appears to be set for stratix? Have a look and see.

    You are correct. So Rakesh if you are using the same device then this is probably the cause.

    Hi everyone ,

    Iam really happy that it's working fine now. What I have done is just recompiled the full-featured version of cyclone2 edition reference designs and the I just updated the symbol after compiling. Then it worked fine.But Iam still not sure of the root cause of that problem.

    Do you mean the 1C20 Full Featured reference design? If that's the case then you probably ran into the same PLL problem that joe98 encountered. So while you were having problems you were using the sof file that came in that project without compiling? Did you have to open the SDRAM PLL and change it to Cyclone for your compile to work or did you simply compile and that worked?

    Cheers

    I did not change the PLL . But I have re-compiled it and updated the symbol and it just worked.
