We integrate the network, not just a single node.
Vehicles are moving from domain controllers to zonal layouts. OEMs need partners who understand routing, gateway firmware, LIN/CAN-FD coexistence, SecOC, and diagnostics — and can wire multiple ECUs together on a bench.
This experiment is that bench: two MPC5748G gateways, an S32K144 edge node, secured traffic, and a UDS stack running end to end.
Technical Overview
Hardware: MPC5748G DevKit pair, S32K144EVB, dual CAN-FD interfaces, diagnostic CAN channel, scope, and debug links.
Tool flow: DBC/ARXML conversion → architecture diagram → bus load → gateway routing (Gateway Core C) → SecOC → rest-bus test → UDS flash.
Gateway Core C deploys on MPC5748G with a single platform transmit hook. UDS SecurityAccess uses generated seed-to-key DLLs. SecOC uses generated authenticators, not seed-to-key.
What This Demonstrates
- Multi-ECU gateway network (CAN-FD + LIN)
- Cross-bus routing and translation
- SecOC-authenticated onboard traffic
- UDS diagnostic stack
- Gateway Core C on real gateway silicon
- Rest-bus simulation of missing ECUs
- Bus stress testing with signal integrity checks
