When Flash Isn’t Just Flash: Real-World Lessons Using FATFS, LittleFS & Other Filesystems in IoT Devices
Choosing a filesystem in embedded firmware looks simple — until real devices start writing logs, staging firmware updates, caching sensor data, or recovering from unexpected resets. What starts as a neat API turns into challenges involving corruption, wear, mount-time failures, memory stalls, directory explosions, and behavior that rarely shows up in
