Hi, I am using the DE2-115 with uclinux v3.7 and our pin out are the same as you had stated.

SCLK -> SD_CLK -> PIN_AE13 (Clk)

MOSI -> SD_CMD -> PIN_AD14 (Data Input)

MISO -> SD_DAT -> PIN_AE14 (Data output)

SS_N -> SD_DAT3 -> PIN_AC14 (Chip Selection)

I still don't see the mmc_spi message on the bootup screen. I check the kernel setting many times and can't think of anything I did wrong??

Please help anyone!
