12 years agoAre your NIOS and your "Pixel Buffer DMA Controller" both attempting to use the same portion of SDRAM (e.g. base address 0x00000000) ? In other words, the DMA is writing to the location in SDRAM where the NIOS instructions or data are stored.
There is no problem having multiple components connected to the same SDRAM. The problem which you may eventually run into is lack of bandwidth to the SDRAM to support your video, but just adding a NIOS isn't enough to cause that.
