I'm trying to create a system in which I can access the SD card (not as root file system). I've compiled a linux kernel with mmc support (static, not module), I can see the mmc controller gets registered when the system starts, but I'm unable to access the card (whose image is specified using the -sd command line option). The block device (mmcblk..) does not appear in /dev (when using udev), and if I create it manually, it's unusable. Am I missing anything?
