On AM335x, JFFS2 support has been super-seeded by UBIFS. Reasons for disabling JFFS2 support. UBIFS file system is recommended for NAND File system over JFFS2 as it is seen as JFFS2 successor with significant improvements in scalability and NAND support. Compatibility of ECC layout across all components. RBL, U-boot SPL all uses BCH8 ECC scheme.

Nov 24, 2013 · A successor for JFFS2 exists and is supported by the kernel (UBIFS file system support). The Unsorted Block Image File System (UBIFS) also competes with LogFS. The Linux kernel also supports LogFS (LogFS file system). ROM-based embedded systems need support for CramFS...

In contrast, JFFS2 does not have write-back support and all the JFFS2 file system changes go the flash synchronously. Well, this is not completely true and JFFS2 does have a small buffer of a NAND page size (if the underlying flash is NAND).
