Hi, I don't understand why you'd want to mount JFFS2 on RAM ? It's specific to deal with flash. Perhaps others can discuss. When you unmount, make sure you're not in the directory you're unmounting. As an example, say I mount sdd1 to a local root directory /mnt : mount /dev/sdd1 /mnt to unmount, also make sure you unmount on the *local* mounted dir : umount /mnt HTH B rgds Kris -- Best regards, Kris _______________________________________________ uClinux-dev mailing list uClinux-dev@uclinux.org http://mailman.uclinux.org/mailman/listinfo/uclinux-dev This message was resent by uclinux-dev@uclinux.org To unsubscribe see: http://mailman.uclinux.org/mailman/options/uclinux-dev
