DMA between Custom Component and SRAM

Hi Kalyansrinivas,

thanks for your answer!

Good to know, that the SOPC connections are correct.

Have you had a look at the custom component VHDL code? I read that the DMA is only working if the components use flow control. I would be happy if somebody could confirm that my component provides a correct flow control interface.

If you look in the folder "software" then you can see what code I used to test the system. It is mainly a DMA example from the NIOS II Software developer Handbook (or was it the Quartus II handbook, I can't remember right now . . .).

Maybe somebody else can make annotations to this project if there are things that are heading into the wrong direction.

@Kalyansrinivas: I will let you know if your hints helped me to get the system running. We have to wait until next week because I don't have the hardware available, right now.

Thank you,

Maik
