    Sd card read/write

    Hi, I have formatted the card with FAT32 with 32 kb chunk size. And yes I have already used different sd cards. I was thinking about using linux on fpga. Should I? Can you point me in that direction? Thank you for your time.

    Sd card read/write

    Hi, I am new to fpga. I am trying to read/write from sd card zusing the zybo zynq 7000 and I found the Xillfs example. For some reason the mkfs function always fails. I don't know if there is a problem with my design? I have enabled the sd0 in zynq processing system. Is the something else I should do? Any help is appreciated.
