Development of a Safe Architecture for Embedded Systems Using Linux and Zephyr RTOS

Embedded systems often involve safety critical applications, meaning that the malfunctioning of these systems would lead to catastrophic consequences. In this thesis project, a cross domain comparison of the industry specific standards for safety in embedded systems is be provided. After this, following the guidelines provided in ISO-26262/IEC-61508, a failure modes and effects analysis was performed on the implemented system, which consists of a STM32MP157F-DK2 board, on which two cores of the same SoC communicate through Remote Processor Messaging. One core runs OpenSTLinux, and the other the real-time operating system Zephyr. Based on the results of the failure modes and effects analysis, a combination of the addition of some headers to the message, and the implementation of cyclic redundant check, solved some of the issues pointed out
