We are happy to announce support for LittleFS file system images. The new LittleFS Format package lets you browse and extract files from LittleFS images directly within the application.
LittleFS is a block-based file system designed for microcontrollers, with a focus on power-loss resilience and wear leveling. It is widely used in embedded devices built on platforms such as ESP32, STM32, nRF52, RP2040, and Mbed OS. LittleFS stores metadata in redundant block pairs and organizes file data using either inline storage or a CTZ skip-list structure that provides efficient random access. Having native support in Cerbero Suite means analysts can inspect firmware dumps and flash images from IoT devices, sensor nodes, and consumer electronics without needing external tools.
