Hi, I have written a dummy (ram disk) block device driver for linux kernel. When the driver is loaded, I can see it as /dev/mybd.
I can successfully transfer data onto it using dd command, compare the copied data successfully.
The problem is that when I create ext2/3 filesystem on it, I have to use -o loop option with the mount command. Otherwise mount fails with following result:
mount: wrong fs type, bad option, bad superblock on mybd, missing codepage or helper program, or other error
What could be the problem? Please help.
Thanks.
