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.

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,
