Reading data from Flash

[Altera_Forum]

Hi, 

 I use an Altera DE2-115 board.  I have written some data into my flash memory in the board using the control panel tool.  Now, I intend to read the data and process it by a logic to be implemented in QuartusII.  Suggest ways to read the data from the flash into the QuartusII project.   Thanks Nadeem

Use a Flash interface IP core:

You can use a NIOS processor to read data from this memory and make it available for any other module inside your project.

I'm not sure if you can do this in the BSP Editor, but you can try. 

 You can check if it shows in the Linker tab the Flash Memory, if it's there you can have access to this part of the memory creating a variable/vector in this section (using .xxxx). It will probably work this way, but it'll be slow.  I think the best way if you're going to use a NIOS processor is to transfer data from the FLASH memory to the SDRAM or Onchip Memory.

Thank you

If you have never worked with NIOS before I suggest you follow some tutorials, and use the Application Examples in NIOS2 EDS like the Hello World Example. 

 Here are some links to altera courses on NIOS2 processor: http://www.altera.com/devices/processor/training/emb-training.html
