![]() If a single block is written to over and over, it will become unable to store new data. Each block of flash memory supports only a limited number of erases, after which they become unreliable. Second, LittleFS implements wear leveling to extend the life of the flash memory chip. Instead, the file system's state will simply reflect the last successful write. If power is lost while updating the file system, the update being written may be lost, but the file system will not be corrupted. ![]() This is critical for embedded devices that can lose power at any time, especially battery powered products. It provides two different features to help with this.įirst, LittleFS organizes its on-disk data structures to be resilient to loss of power. LittleFS is designed to ensure that the file system does not become corrupted and does not wear out from overuse. ![]() File names can use UTF-8 encoding, allowing non-ASCII characters to be included in file names, which can be convenient for projects deployed world-wide. While long file names are not always essential, they can ease development by allowing more descriptive file names to be used. LittleFS also allows file names of up to 254 bytes. Many embedded systems are so-called flat file systems which don't support directories. This is very important for managing a large number of files and for interoperability with code that runs both on embedded devices and computers. LittleFS supports real directories, just like the file system on your computer. Benefits of LittleFSīoth the design and implementation of LittleFS meet the needs of today's embedded projects, combining essential features with ease of use. This blog post explains the benefits of LittleFS and how to start using it in your projects. LittleFS is now fully supported in the Moddable SDK. ![]() The LittleFS file system created by ARM is an excellent alternative to both SPIFFS and FAT, that is also easier for developers to use. These file systems work well, but have limitations that make them difficult for developers to work with, especially developers more familiar with the full featured file systems on computers. Popular choices include the FAT file system and SPIFFS, and the Moddable SDK supports both. Projects that need a file system have a choice of which file system to use. Microcontrollers don't usually have a built-in file system. LittleFS – the Best File System for Embedded Projects? Introduction ![]()
