ML402 card (video starter kit) : Read/write on the ddr

Hello everybody,

I am trying to make a software video processing with the VSK. For this, I want read video data from the DDR, applied the convolution algorithm and write the modified video data in the ddr. but I have some probleme to read/write in the ddr. Can anyone tell me how we can read and write data in the ddr?

Thanks.

I have made a lot of test. In this test I have first tried to write one data on all the ddr, for this I write in fifo[512]ddr0_wa numbers from 0 to 511, after I write for example "767858038" in all the fifo[512]ddr0_wd, but I have nothing.
