Help using SDRAM with SDR_SDRAM controller

you can try to make a pointer that points to the start address you want to write to (somewhere in the address span of the SDRAM).

Then issue memcpy with source and destination pointers. See documentation of memcpy.

Or, you can do a loop manually :

short* psrc = xxxx //location of the source data

short* pdst= yyyy //some address in the SDRAM address space you need to write to

for (int k=0; k < 640*480; k++)

*pdst++ = *pscr++

If you don't understand this, please try to get some experience on C/C++ first.
