Hi, i'm working on my design with NiosII , two sdram controller , 3 dma and some other peripheral. Now all hardware and software seem working fine, except DMA. The program is working correctly...

Hi Roberto,

I would use the HAL implementation instead of IOWRs directly, the HAL works fine for DMA. Also, I would, if you have modelsim, do a functional simulation to see what your DMA tranactions are doing.
