Ok. I have read the README file. Make a SOPC NIOS configuration with the SD card hardware in it. Compiled the kernel with the driver in it and the device comes up, however how do I use the device. Cat /proc/devices and I get 2 mmc devices with a major number of 254. I created mmc and mmc0 (minor numbers 0 and 1) in the /dev directory however I cannot mount the SD card as it says the device does not exist. What am I doing wrong? Thanks in advance.
