FPGA to SDRAM AXI Transfer

Never mind. Found it.

Hello,

I'm doing a project with Arria V SoC using the HPS and FPGA parts. In the FPGA, I have a custom IP with AXI Master interface on it.

This IP should read and write from/to the SDRAM directly. However, I can only do read operation! The write operation does not work.

The data in SDRAM is provided by HPS (running Linux). For now, I'm using /dev/mem to write the data to the SDRAM.

Using the same method, I found that the data is never written from FPGA.

1. Can you help me with this issue? Anyone has already done a work using AXI and SDRAM?

2. In Qsys, my AXI master should be connected to the SDRAM, right? Did I do some mistake? I connect it to f2h_sdram0_data, not f2h_axi_slave on hps_0.

3. Is there any configuration that I need to do in the AXI to perform read and write?

Thank you so much for your help.
