Embedded Firmware Types

In embedded systems, not all firmware is the same.

✅ System firmware → the foundation: bootloaders, drivers, HAL, RTOS. It initializes hardware and provides core services.
✅ Application firmware → the behavior: sensor fusion, motor control, logging, IoT logic. It defines what the device does.

Difference? System = infrastructure. Application = functionality. Together, they make a complete embedded stack.
