Hi there~~
 
I build yaffs2 file system, then I copy a file to mounted nand flash. but, after unmount, and remount, I cannot find that file.
 
but, when I try command df -h, flash used area is increased than before.
 
I don't understand this problem.
 
I already checked /proc/mounts, /proc/yaffs, /proc/mtd, but, I cannot find problem from those. I may be seen ok.
 
please, tips to me. 
 
I use Samsung nand flash. (K9F2G08UM). it has 8bits data bus, 128K pages, 2048 Blocks, 64 bytes oob, 2048 bytes page register. Driver is no problem in my checking...
