Nettet3. mar. 2024 · Race condition between thread/interrupt signalingPosted by wiwix on February 26, 2024Hi all, I’m trying to debug a serial driver. A binary semaphore has been used to signal data reception from the serial line interruption and the reading task. In rare conditions, my reading task is not awoken, whereas the received byte has been … NettetEven though the if condition on line 23 makes a check for a value which is divisible by 5 and it only then prints randInt, it is just after the if check and before the print statement, i.e. in-between lines 23 and 26, that the value of randInt is modified by the modifier thread! This is what constitutes a race condition. For the impatient, the fix is presented below …
