Download PDFYAFFS supports both NAND and NOR flash, with various page sizes from 512 bytes to 16KB and beyond. Both SLC, MLC, and TLC NAND are supported.
YAFFS is designed for low memory footprint. Exact requirements depend on flash size and configuration, but it's suitable for resource-constrained embedded systems.
YAFFS is designed to work directly with raw flash, which gives it full control for reliability. Using it over an FTL is possible but removes some of the reliability benefits.
Yes, YAFFS integrates with the Linux MTD (Memory Technology Devices) subsystem for accessing flash hardware.
Migration typically involves reformatting the flash partition with YAFFS and copying data. We can help with migration planning—contact our consultancy team.
The YAFFS mailing list is active and helpful for general questions. For commercial projects, our consultancy team can provide dedicated support.
YAFFS has an active community of developers using it in production systems worldwide. The mailing list is a great resource for questions, discussion, and announcements.
