Some very useful features like wear leveling and proper usage of the OOB data are not yet implemented. Another problem is that you must write a boot loader that understands JFFS or partition the memory somehow and deal with the bad sectors. Please see the MTD list [EMAIL PROTECTED] and its archives, the subject is being discussed periodically. Personally I am developping a filesystem dedicated for NAND Flash circuits that will use the OOB data as an essential part of the filesystem and should provide better performance and much easier booting than JFFS (which has been developped for NOR Flash). But first I have to get the rest of our new board up'n'running... -- Paul Chitescu [EMAIL PROTECTED] http://pchitescu.myip.org/ ICQ:22641673 Any spammers will be painfully squeezed into /dev/null _______________________________________________ http://lists.arm.linux.org.uk/mailman/listinfo/linux-arm http://www.arm.linux.org.uk/armlinux/mailinglists.php Please visit the above addresses for information on this list.
