Ok, But what I have to do with this, 
 JFFS2 still trying to write not sector alligned data:
debian:~# rm /mnt/nand/a*
nand_read_ecc: from = 0x0000c800, len = 16
nand_read_ecc: from = 0x0000c834, len = 16
nand_read_ecc: from = 0x0000c868, len = 16
nand_read_ecc: from = 0x0000c89c, len = 16
nand_read_ecc: from = 0x0000c8d8, len = 16
nand_read_ecc: from = 0x0000c910, len = 16
nand_read_ecc: from = 0x00198000, len = 1052
nand_write_ecc: to = 0x0000c940, len = 1052
