can you know the improvment of uClinux-dist-2008R1-RC8 at VFAT optimize of writing speed? the version of 2007 is too slow, about 50kB/s. can you tell me why? the pure nand writing speed is over 1MB/s , but after mounting vFAT, the speed is too low.

we already told you that using VFAT on NAND is not workable. it does not include bad block handling which means the filesystem WILL be corrupted over time and you cannot repair it.
it also does not do things like wear leveling or take into account the fact it is running on a flash device. so it wont be optimized at all to account for the erase/write cycle like a real flash file system is.
