FPGA to HPS SDRAM Interface

Hi, I want to use the FPGA to HPS SDRAM Interface, in kind of an Avalon MM Bidirectional 64 Bit. Logic is done, simulation results are as expected. I build the design and loaded it into the SoC...

Hi Thomas,

I wish to use the FPGA2SDRAM bridge in my design, as I am having bandwidth issue accessing memory over the FPGA2HPS bridge. Would you kindly explain what steps are required for the FPGA2SDRAM bridge to work?

For instance, so far I have enabled FPGA2SDRAM bridge (single port with 256bit bidirectional AvalonMM interface). Then I have connected the Avalon-MM masters to that interface in Qsys. But what's next?

Appreciate the help.
