Hello, Does anyone have experience of writing their own Avalon MM master port in Verilog to interface to the Altera SDRAM controller? I have written the simplest code I could think of to t...

1. You generated SDRAM controller from Megacore IP and plugged into SOPC builder.

2. Now, you write your own custom Avalon-MM to write/read from SDRAM

For me, I have SDRAM controller from IP. I connected the SDRAM to SGDMA mm_to_st and st_to_mm in SOPC. Now, I write my own custom Avalon-ST protocol in between mm_to_st and st_to_mm to verify that my interface is working correct.

If you want to go this way, SGDMA. I will post you the custom interface to verify it.
