WebAfter running these lines of codes, all of the values at those memory locations stay the same and are not altered with the operations that were supposed to be performed. E.G. : //DWT_CTRL_CYCCNTENA_Msk = 1 DWT->CTRL = DWT_CTRL_CYCCNTENA_Msk Should result in the value of DWT->CTRL being 0x40000001 but it remains at its default … WebAlso check the data value before the delay, and re-check the data value after delay; if the values mismatch, we infer a race of unknown origin. To detect data races between plain and marked accesses, KCSAN also annotates marked accesses, but only to check if a watchpoint exists; i.e. KCSAN never sets up a watchpoint on marked accesses.
