Hi, Which formate you use for sdcard partition? Did you formate card with ext2 etc ? which device node you use to formate ?
i.e fdisk /dev/mmcblk0 (on linux PC ) When you mount sdcard in linux ( on your hardware ), which device node you use and which file type you specify ? i.e mount -t ext2 /dev/mmcblk0 /mnt ( linux running on your hardware ) Whats message on console after mount command? Go to /mnt, try to create some file. If this is working that means your mount process is fine. If mount is fine then only 'umount' works otherwise there is no meaning to run 'umount'. Let me know if you still have issue after checking above procedure.
