LevelX: An Embedded Flash Memory ‘Balancing Master’ to Solve Issues of Uneven Flash Lifespan, Bad Blocks, and Data Loss During Power Outages

2026-06-26 by boardor

Hello, friends! If you’ve ever worked with NAND/NOR Flash, you surely understand the pain: after tens of thousands of erase/write cycles, some blocks start to ‘fail’, leading to data loss and performance degradation… It’s frustrating! Today, let’s talk about a powerful tool—LevelX, which can perform a perfect ‘check-up’ and ‘exercise’ for your embedded flash memory, … Read more

Understanding NAND Flash: From Basics to Abandonment

2026-02-18 by boardor

The price differences of mobile phones with varying storage capacities are significant. For those who are frugal, purchasing an external hard drive to regularly transfer phone data and storing the hard drive in the refrigerator is a practical solution. This anecdote highlights the characteristics of external hard drives, such as the need for periodic power … Read more

littlefs: A Lightweight File System Designed for Microcontrollers (MCUs) and Flash Devices

2026-02-16 by boardor

littlefs (little file system) is a lightweight, embedded file system written in C. It is not as heavy as ext4 on Linux, but it provides POSIX-style file and directory operations (open/read/write/rename/remove, etc.). The focus is on providing “strong power failure fault tolerance” and “dynamic wear leveling,” while tightly controlling RAM/ROM usage, making it suitable for … Read more

Flash Lifetime Prediction and Monitoring in Embedded Systems
