Accessing SDRAM on DE2

Question

Hi

I need to use the SDRAM/SRAM/FLASH. I can use any one the above. I have setup a NIOS II processor with all those peripherals and I have also run a hello_wrld program on the processor.

Now I don't know how to go ahead. i couldn't find any tutorial to do that. Where can I get the library files? Do I have to write a lot of code to do this? Please help me. This is the first time I am working with an embedded processor.

You should check out nios ii hardware development tutorial (http://www.altera.com/literature/tt/tt_nios2_hardware_tutorial.pdf).

Page 29 describes simple software development, although I would recommend following the whole tutorial if you've never done this before.

After completing this tutorial, you can take a look at creating multiprocessor nios ii systems tutorial (http://www.altera.com/literature/tt/tt_nios2_multiprocessor_tutorial.pdf), which uses SDRAM for a multiprocessor system.

You can simply ignore the multiprocessor aspect of it, and focus on getting only one processor to run.

Good luck! http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/smile.gif

Can you please send me your complete project source code &amp; docs at my id addy3177@yahoo.com. The one which uses hello world program. Secondly, If you have used sdram successfully, send that as i require similar work for my project. Thanks in advance  regards, aditya

Altera has some tutorials to help people get started using the DE2 Boards. Located on their university program website. (http://www.altera.com/education/univ/materials/manual/unv-lab-manual.html)

And specifically there is a tutorial for using the SDRAM:

sdram tutorial verilog (http://www.altera.com/education/univ/materials/manual/labs/tut_de2_sdram_verilog.pdf)

or

sdram tutorial vhdl (http://www.altera.com/education/univ/materials/manual/labs/tut_de2_sdram_vhdl.pdf)
