I am using a Zynq7000 with NAND 512MB and I am trying to deploy Linux on NAND
memory. I use a custom built kernel with minimal features (UBI and UBIFS
support are enabled and mtd-utils installed). I can ubiformat an mtd
partition, I
can ubiattach and ubidetach it but whenever I try to mount the
partition I get this error.
mount: mounting /dev/ubi0:ubi-rootfs on /mnt/ubifs failed:
No such device
(ubi-rootfs is the name of the partition, I am sure about it)
I am sorry if I am asking about a problem that has been reported before,
but I am
new to this list
Thanks in advance,
Michael

Do major/minor numbers match? If we create the dev node by hand, it is hard for kernel to notice that. UBI (and even driver base) seems doesn't know and doesn't care if device nodes already exist. UBI just checks the ubi_devices, registers devices, and tells udev to make node. Although everything seems ok, `mount' will fail because of wrong device node. However, the "device node" is removed when detaching without any warning or error message. In this way, UBI could delete the file without user's permission. Is this appropriate? Shall we add some code in ubidetach to detect whether the "device node" to be removed is correct? thanks, Sheng > > Thanks, > //richard > > ______________________________________________________ > Linux MTD discussion mailing list > http://lists.infradead.org/mailman/listinfo/linux-mtd/ > > ^ permalink raw reply [flat|nested] 23+ messages in thread
