The IMUtility (IncorporatedMISRAUtility Code) originated as a sub-repository of theIMBootloader project. After a thorough review of the available safety-critical utility open-source projects in C, we realized that none of them met our standards. Therefore, we made the decision to create our own project and make it publicly available.

Our team has meticulously laid the foundation for everything necessary to ensure the code meets the rigorous standards required for safety-critical applications. Presently, we have incorporated unit tests using theUnity framework, code coverage using gcov/lcov, ensured code style conformance through Astyle formatting, and implemented cppcheck with all checks enabled. Additionally, we have enforced MISRA C 2012 checks using both cppcheck andECLAIR, sponsored by Bugseng (lastcommit with ECLAIR analysis).

However, to further enhance the project's quality, we intend to achieve 100% coverage where feasible. This will serve as an additional layer of assurance that the code is of the highest quality and complies with safety-critical standards.

ECLAIR version 3.13.1, is certified for use in safety-related development in compliance with the prescriptions of the following functional-safety standards:

• ISO 26262 up to ASIL D
• IEC 61508 up to SIL 4
• EN 50128 up to SIL 4
• EN 50657 up to SIL 4
• IEC 62304 up to Class C
• ISO 25119 up to SRL 3
• ISO 19014 up to MPLr e

We are happy to see contributions. You can add utility code that you see is missing, improve existing one, or open issue tickets.Before you open PR:

• write unit tests for your code
• runmake format
• runmake cppcheck
• runmake misra

After PR is opened, we will review your code, and after that code can be merged into the main branch.
