    Hi, Windows can read and write to SD Card ! :-)

    Do you mean that you want a board able to read and write to SD Card ?

    I think the sd card should be readable by windows, shouldn't it ?

    If so, it implies a FAT (File Allocation Table) and a "driver".

    Altera tutorials contains examples to read from SD Card.

    There is a MP3 touchscreen player built with an Altera dev kit. Find it in this forum.

    It is not trivial for a beginner.

    Look at opencores.org

    Free or opensource SD CARD drivers you can find have poor performance because they use only one data signal while SD CARD has 4 data signals

    There are also drivers (Elcamino, ...) that you can pay thousand dollars to do it.
