i'm using a Spartan3ADSP-1800 board to run linux as embedded system on the microblaze core. for some days, i'm trying to make a microSD card accessible from linux for data storing purposes. the problem is that there are some issues concerning the right IP configuration. did anyone ever use a microSD card connected to the board's PMOD connector? can i use the xilinx SPI controller or do i have to use some sort of special SDIO controller? how to set up the right pin configuration in the .ucf file? (constraints)
i am completely new to this subject and would appreciate some help!
