bemicromax 10 - sdram CKE pinout needed or not ?

I have a tutorial for the cyclone III for the core commander board which i am trying to translate to the bemicromax 10 . In it .sdram_wire_cke is defined as

.sdram_wire_cke ( ),

so it is declared but not being used for some reason ?? in a more modern tutorial for the BEMICROMAX 10 i found that it is declared

.sdram_cke (SDRAM_CKE), // .cke

i am unable to boot the system into nios until i declare some more pinouts such as fpga_reset.i also need a regulator for the sd card which is shipping from arrow. the sd card is the main function of the program so i need to perfect everything before i will know if it is ready to boot or not

does anyone know is cke is needed or not ?

sorry for blowing up the board with all these error messages, i am doing my first beginner project and i do not want to have so many unknowns that it will not boot.

    Instead of using an example for a different chip, try out some of the examples on http://www.alterawiki.com/wiki/bemicro_max_10 You will have better luck with these. I don't recommend porting a design to a different chip as a first project for a beginner. Start with an example written for your board and modify it in small steps. Save previous versions so you can go back if something doesn't turn out right.

    Since it looks like the Bemicromax 10 doesn't have a SD card slot on the board, there won't be any examples using it. I guess I wasn't clear in my previous posting. I'd suggest you try some of the tutorials made for the Bemicromax 10 card. Build them unmodified to make sure you understand how to build projects and load them on the board. These are known good examples that you can use to familiarize yourself with the board. Once you know how the whole Quartus and QSYS process works, you could add a custom QSYS component to connect your SD card.

    Without looking at the whole project I can't tell what cke is.

    i have made a few projects (one an IDE controller using a pic microchip) i just wanted to do something advanced. so i am pretty proficient with soldering and i/o . I went ahead and added the cke pinout to see what happens, should be able to tell you something in a day or so when my 3.3volt regulators get here
