Hi,
I have a Linux newbie filesystem question.
On Linux command line: mount -t yaffs2 /dev/ram2 /mnt/mtd
Where ram2 is a block device with major number RAMDISK_MAJOR, then yaffs2_mount() is executed. (The consequence is failure but I am not interested in the failure.)
However, when a
mount -t yaffs2 /dev/mydevice /mnt/mtd
where mydevice is a block device with major number MTD_BLOCK_MAJOR, then yaffs2_mount() is not executed. Linux couldn’t find an entry in the bdev_map->probe[MTD_BLOCK_MAJOR] (in genhd.c). Is this because I don’t have a MTD Chip Driver installed for YAFFS2 MTD “user” module? (I currently do not have the driver yet; just experimenting right now.)
During initialization, I do see init_mtdblock() is invoked and major_names[MTD_BLOCK_MAJOR] is initialized (register_blkdev() is invoked), but bdev_map->probe[MTD_BLOCK_MAJOR] is not initialized.
Advise pls.,
Phong.
