SDRAM Initialization

Hi everyone, I was wondering if there's an easy way to fill the SDRAM with some sort of data from the host PC? nios2-download kinda does it, but I have to have the processor then, which I don't...

If the desired memory footprint is small enough, you could always preload it on the Flash, then load it on to the SDRAM at powerup. Otherwise, you'd have to hang an external Flash or EEPROM off your GPIO for your preload data if you need more room.
