MISRA is specific to embedded automotive systems. I believe it specifies C or C++ standards exclusively - or rather, subsets of several releases of those language standards. As a matter of practicality, it requires automated support for MISRA compliance checking. So if those tools are not available for a development environment, that environment would not be practical to use.That's interesting. Do they also limit what languages\compilers you're allowed to use?
Beyond the compiler, there is a requirement for controlling the impact of any single point of failure. So not just any microprocessor or any operating system can be used.
