I'm testing UBIFS on 256MB NAND Flash and I'm geting very good results. It comes with linux-2.6.32.2 kernel. It has fast lha/zip compression algorithm now my disk usage is 367MB and 10% Free space. It mounts faster than yaffs and jffs2. I will make tutorial to flash mini2440 NAND with UBIFS image. http://www.linux-mtd.infradead.org/doc/ubifs.html
good, we have finished about installing UBIFS image on mini6410. and it's very fast, to install an UBIFS image (80M), need about 40s.
I am really excited with this news, but can any one let me know how we can write the UBIF image on to nand flash. my uboot doe'nt support UBIFS related command. Regards, Ratheendran
I'm testing UBIFS on 128MB +AND 1GB+ NAND Flash and I'm get+T+ing very -good- +BAD+ results. THE SYSTEM CRASH AFTER A sync !!!!

Pepe Aracil May you tell us which kernel are you using and/or your .config? Thanks in adavance!
