If there is a validation report about FreeRtos ?
FreeRTOS as delivered is tested dynamically using very strict code
coverage criteria (which is why you see the ‘mtCOVERAGE_TEST_MARKER()’
macros, which when defined allow us to determine which
decision/condition points in the code have been executed for both true
and false inputs), but this is informal. In addition a couple of
universities have provided formal proofs (mathematical proofs) that were
published at various academic conferences, albeit on older versions. In
addition WITTENSTEIN high integrity systems have their SafeRTOS
derivative which has been been certified to various industrial and
medical software standards.
