Hi, all,
Can anyone tell me how to move data from on-chip memory (part of my hardware design) to SDRAM? Thanks a lot.Link Copied

Well, do you have a working SDRAM controller in your design? If you do, it will show up in the address map (or check the SOPC builder for the appropriate address range), define a few pointers in your target program and copy with a simple memcpy() routine.

--- Quote End --- Thanks Arjan, I know about a few the SDRAM addressing, my current problem is how to access my on-chip memory which is in AUTO mode instantiation on Stratix II. And the on-chip mem contains huge amout of data which forbids me to write register and address decoding for each single address. Could you consider one more time? Thanks,

Look at the example designs that comes with the development boards. That will show how to build a working system in detail.
