URGENT: Peripheral to Memory DMA Transaction

yes.. my RAM (both SRAM and SDRAM) is 16 bit, peripheral is 32 bit and DMA is 32 bit as well... so for the IOWR during writing into source (SDRAM), do i have to use IOWR_16DIRECT?

update:

now, initially... i use..

for(i=0; i<100; i++)

{

IOWR(src, i, i);

printf("initial: %d\n", IORD(src, i));

}

//same DMA code

for(i=0; i<100; i++)

{

printf("end: %d\n", IORD_16DIRECT(dst, i*2));

}

and the result... it is ok to for 0 until 49, then the rest all is 1.
