When I insert an SD card into the DM3730 wireless eval board, it is automatically mounted to /mnt/mmcblk0p1, but it does not have the correct permissions for me to execute a file (SD card is FAT32). I added a fstab entry that allows me to umount it, then mount it with the correct permissions. Before I added a line for /dev/mmcblk0p1, there was no entry in fstab.
So what is auto mounting the SD card and how do I control the options?
