Huh? IMO there is no difference between 770, N800 and N810 in this regard. All of them use raw NAND access without any translation layer.

Well I guess someone could even backport UBIFS from 2.6.22 to 2.6.21 to have it running on current devices with Diablo. Maybe such backport already exists. It would need some initfs hacking and fulll rootfs reflash of course.

It is easier to just boot from SD and forget about jffs2 (or UBIFS), though.

I wonder about UBIFS future in the light of eMMC chips (like the 2GB MoviNAND one in N810) which provide transparent block devices without any need for messing with raw NAND.

Still, plain non-managed NAND chips are cheaper and perhaps UBIFS can work better and give better control than any FTL hidden inside managed NAND chip so there is future for UBIFS too.

I wonder whether N900 will ditch internal OneNAND for bigger eMMC chip or ditch eMMC for large UBIFS volume. In any way 256MB jffs2 is quite limiting today.
