(Prepared 17 April 2026) 1. Executive Summary The Flash Loader 7.2.4 (Sec 2.4) family, comprising the Lite and Slave variants, is a firmware‑upgrade utility used primarily in embedded‑systems development and field‑service environments. It enables secure, in‑field programming of microcontroller‑based devices (e.g., automotive ECUs, industrial controllers, and IoT gateways) via a host PC or a dedicated programming console.

| Aspect | Lite | Slave | |--------|------|-------| | | Stand‑alone host application that initiates and manages the flashing process. | Minimalist agent that runs on the target device, receiving commands from the Lite host. | | Typical Deployment | Windows/Linux host PCs, development benches, or service‑tool laptops. | Embedded target hardware (often with limited RAM/Flash). | | Security Level | Implements Secure 2.4 protocols – mutual authentication, encrypted payload, and integrity‑check (SHA‑256). | Mirrors the host security model but with a trimmed code‑footprint. | | Licensing | Commercial, usually bundled with the OEM’s development kit or provided under a signed agreement. | Distributed together with Lite under the same license terms. | | Supported Interfaces | CAN, Ethernet (TCP/UDP), USB‑Serial, SPI (via external adapters). | CAN, UART, or direct memory‑mapped interface to the host. | (Prepared 17 April 2026) 1
