Bootloader con Radice di Confidenza Hardware e Architetture MCAL Zero-Wait State
AutomotiveFirmware definisce l'interfaccia critica tra silicio e servizi per ECU zonali. Implementando catene di avvio misurato ancorate all'hardware e rimappatura atomica A/B, garantisce avvii sicuri in frazioni di millisecondo.

Stabilire la Radice di Confidenza Hardware per Architetture di Calcolo Zonali
In un veicolo software-defined, ogni microcontrollore periferico rappresenta una porta di accesso per potenziali attacchi. AutomotiveFirmware impone la verifica crittografica prima del rilascio del reset della CPU: la boot ROM di stadio 0 convalida gli hash memorizzati negli eFuse OTP.
Core Engineering Areas
- Hardware Root-of-Trust Secure Boot — Deploying hardware security modules (HSM/SHE) to verify RSA-3072 or Ed25519 digital signatures on application firmware before releasing core reset lines.
- AUTOSAR MCAL Driver Architecture — Configuring low-level Port, Dio, Spi, and Can drivers to operate with zero CPU polling via Direct Memory Access (DMA) ring buffers.
- Dual-Bank Atomic Firmware Flashing — Partitioning on-chip flash memory into symmetric Bank A and Bank B regions to enable seamless background flashing and instantaneous rollback.
