HI, I m using the jffs2 filesyem support on my linux kernel version 2.4.20 and MTD subsystem version 2.6.9 with BBT and ECC management support in MTD subsytem.Is linux kernel 2.4.20 supports the yaffs filesystem ? Also I have a 16MB of NAND flash on my system which is ARM based.Which filesystem(JFFS@ or YAFFS) is good in terms of the utilization of the storage space of the NAND flash. Regards Pankaj
