I have a similar configuration. I am building it using DMA instead of SGDMA. I would like to know how different is between SGDMA and DMA. I realized in SOPC, SGDMA has more connections, which I have no idea to connect them. Thank you.

Hi Waiyung, _matt_,
I am trying to use SPI core in conjunction with DMA controller on Cyclone IV. Did anyone of you try the same and able to achieve it? I am newbie to this field. I have the qsys design which has NIOS II and SPI core at this moment. With this, I am able to read and write the bytes. Now, I would like to use DMA controller with SPI to send and receive the bytes without intervening the NIOSII.
I would be glad, if you can help me with some tips or examples to further proceed with this design. Please let me know if you have any link or design examples which can give more insight to me on this. Thanks in advance.
