About the course

Course Overview

This hands-on course equips learners with the skills to implement, test, and secure Automotive Ethernet applications using the Gettobyte AutoBoardV1 powered by the NXP S32K344 MCU.
Through ten structured lab experiments, participants will progress from basic Ethernet driver bring-up to secure, real-time data streaming. The course focuses on AUTOSAR MCAL Ethernet Driver, LwIP TCP/IP stack, mbedTLS security stack, and FreeRTOS task management, using professional debugging and verification tools.

By the end, learners will have the expertise to develop and validate Ethernet-based communication for modern automotive ECUs, integrating both performance and security best practices.

Key Practical Experiments

1. Ethernet Driver Bring-Up & Link Verification – MAC & PHY initialization, link testing, ARP/ping verification in Wireshark.

2. UDP Echo Server – Lightweight, low-latency communication using LwIP/UDP.

3. TCP Echo & Throughput Test – Reliable communication and bandwidth measurement with iperf3.

4. Embedded HTTP Web Server – Live ADC/GPIO data display accessible in a browser.

5. Secure TCP Client (TLS) – Encrypted client connection to a PC-based TLS server.

6. HTTPS Web Server – Secure dashboard hosting with self-signed certificates.

7. Secure MQTT Client over TLS – Secure publish/subscribe for telemetry and control.

8. FTP/TFTP File Transfer – Log/config file exchange between MCU and PC.

9. Secure OTA over Ethernet – Firmware image download, verification, and storage.

10. Real-Time Sensor Streaming via WebSocket – Low-latency data streaming to a web client.
