Running UBI - UBIFS on MLC NAND

Explore the challenges and solutions for running UBI/UBIFS on MLC NAND in this 57-minute Linux Foundation conference talk. Delve into the implementation details of MLC support for UBIFS, including constraints, reduced life time, SLC vs MLC comparisons, read/write disturbance, and the perfidious problem of third pages. Learn about UBI basics, data retention issues, and the UBA implementation process. Gain insights into the life cycle, LEP consolidation, and common case scenarios. Discover practical tips for using UBIFS on MLC and considerations for developers. Presented by Richard Weinberger from sigma star gmbh and Boris Brezillon from Free Electrons, this talk provides valuable information for Linux kernel developers and embedded systems engineers working with NAND flash memory.
