I have a design that requires both a SDRAM and an SD card. I know from this forum that there are some conflicting pin requirements for their clocks. I use a BGA256 IC, which should solve this issue.
I simply could copy the schematic designs for the SDRAM of the Keil, Hitex or Embest development boards, but this does of course not guarantee a flawlessy working SDRAM. Can someone help me with a working reference design (preferably schematic+layout+code)? I do not have special requirements for RAM size, port width and clock frequency/timings.
