DMA Transfer Issue

i see no mistake in sopc.

your ddr memory must be at 02000000 and i do not see any memory at 00100000

you programm uses values from system.h

DDR_SDRAM_BASE is this value 00000000 or is it 02000000 ?

if you modify your application a bit

case 'B': // DDR write operation

DDR_write_ADDRESS = to_hex(&packet[1]);

data = to_hex(&packet[9]);

for(i=1;i<=32;i++)

{

IOWR(DDR_write_ADDRESS,0,data);

iprintf("Written %08x to address %08x \n", data, DDR_write_ADDRESS);

DDR_write_ADDRESS += 1;

data += 1;

}

break;

now could enter any real adress without system.h

now try again 02100000
