Tasks / Responsibilities:
* Safety-Critical Firmware Development: Design, develop, and validate safety-critical firmware for the Cortex-R5 MCU cores in accordance with ISO 26262 standards, including driver development for peripherals like I2C, SPI, and GPIO.
Low-Level Driver and HAL Implementation: Implement and maintain hardware abstraction layers (HAL) and low-level drivers, directly interacting with SoC registers and ensuring precise hardware control.
SoC Safety Mechanisms: Configure and utilize the inherent safety features of the TI TDA4Vx SoC, such as lock-step cores, Memory Protection Units (MPUs), and error signaling modules (ESM). System Bring-Up and Bootloader:
Take a lead role in board bring-up, bootloader development (e.g., SBL), and configuring the system boot flow to establish a secure and safe operational environment. Inter-Processor Communication (IPC): Architect and implement robust, high-performance IPC mechanisms for communication between the safety domain (R5/RTOS) and the application domain (A72/QNX), ensuring freedom from interference.
RTOS & Bare-Metal Development: Develop and optimize real-time applications on safety RTOS (ETAS RTA-OS, FreeRTOS) or bare-metal environments, focusing on interrupt handling, DMA, task scheduling, and memory management for the R5 cores.
Debugging and System Analysis: Perform deep-dive debugging of complex, system-level issues at the hardware/software interface using JTAG debuggers (Lauterbach Trace32), oscilloscopes, and logic analyzers.
Collaboration and Documentation: Work closely with hardware engineers to review schematics, define hardware requirements, and produce detailed technical documentation for firmware design and validation.
