Hello dear

Please can you update if your issue was resolved??
My design testing in eclipse is suffering the same issue exactly. Because my DE board has 1GB SDRAM, so its address range is: 0x4000_0000 - 0x7fff_ffff. But I am unable to fully test it.

Secondly, my DE board consists of another SDRAM (2 separate modules of 1GB each). This second SDRAM addressing in qsys is: 0x0000_0000 - 0x7fff_ffff. I am unable to test this second SDRAM at all.

Please can you help me update about your issue if resolved already?
