Hi,

We are also working on similar type of design on Cycleon V FPGA Board to access SD Card through our custom SDHC Host Controller which has one DMA Controller for PCIe-SD Bridge Inteface. Now, I want to read/write data from/to SD Card through my Linux PCie Driver using Chaining DMA.

Do I need to connect DMA Read & Write Master Port to one of BAR region from FPGA design to read/write data on SD Card from Linux System? or Can I Directly use DMA without assigning into any BAR Region?

Please let me know if anyone has idea about that.

Regards,

Ritesh Prajapati
