Hi! I am searching for a Linux filesystem for use on a SD memory card (mmc device) and I am wondering if yaffs2 can be used on a mmc (and not mtd) device? I know that mmc devices do not allow direct access to flash and SD memory cards already do internal wear leveling but I still think that yaffs2 ECC feature would be useful on it as it is still flash storage and I would like additional ECC on a filesystem level. Is this possible? To store chunk + ECC data on a mcc device? This will probably then be misaligned with underlying flash blocks? And what is maximum partition size yaffs2 currently supports? Mike
