Oui mais sur une carte compact flash tu ne peux pas accéder directement à la flash tu doit passer par le contrôleur, UBIFS comme les autres FFS sont conçus pour fonctionner sur des "RAW Flash"..

Big red note
One thing people have to understand when dealing with UBIFS is that UBIFS is very different to any traditional file system - it does not work on top of block devices (like hard drives, MMC/SD cards, USB flash drives, SSDs, etc). UBIFS was designed to work on top of raw flash, which has nothing to do with block devices. This is why UBIFS does not work on MMC cards and the like - they look like block devices to the outside world because they implement FTL (Flash Translation Layer) support in hardware, which simply speaking emulates a block device on top of the built-in raw flash. Please, make sure you understand the differences between raw flash and, say, MMC flash before dealing with UBIFS. This section should help.
