Dear community,
I am trying to read SD card, which is in processing system (PS), by my design in programming logic (PL).
I tried to use EMIO to create the SDIO interface to PL, and found out the direction of ports (e.g., emio_sdio_clk and emio_sdio_data) is not inout (which is supposed to be). On the PL side, I am planning to use a SPI controller to communicate through emio interface to access SD card.
Is that really possible to access SD card via EMIO from PL for this board? If yes, how should I interface my design to these EMIO ports? I searched through the internet, and there seems to be no successful example about using EMIO in such a way.
Thanks,
LT
