I have recived my DE0-NANO-SOC board and with default mmc i test the spi is working fine.
Now
I have followed everything at https://rocketboards.org/foswiki/Documentation/EmbeddedLinuxBeginnerSGuide
for DE0-NANO-SOC board
after completing i have plug the mmc card and the result is there is no spidev node under /dev
i am confused whats wrong there? here must be spidev up for use from user spcae
