How to driver UHS-II SD card with FPGA

Hi,

 

  Is it possible to drive UHS-II SD card with FPGA?

 

  If possible, and how?

 

  Is there any demo for it?

 

  I also search the forum before, and found some old posts, attached below

Hi @sxl630828191,

 

Zynq MPSoC is now supporting the SD with UHS mode. Please see below image:

you can find more about this in Zynq MPSoC TRM (UG1085) and at wiki page : https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/498772/SD+controller

 

Best Regards,

Hi savula,

 

Zynq MPSoC only support SD UHS-I mode, not the UHS-II mode.

 

and what about drive SD UHS-II by PL side?

Hi @sxl630828191,

 

As of now we are only supporting SD in UHS-I mode only. PL side also not possible now.

@savula

 

So, what's the point that we cannot use PL to drive UHS-II card?

 

Best Regards
