WebSep 26, 2024 · Entering a critical section means that interrupts ( up to a certain priority ) are suppressed. Now you call xSemaphoreTake() during a critical section: how can it block when interrupts are not allowed. PS. Have you defined configASSERT() in a proper way ? I would recommend to either use a semaphore, or a critical section, preferably the former.

It looks working fine but when I try to exit the critical section with …
WebOct 20, 2024 · The reason for calling vTaskDelay () is to give other tasks a chance to run while this task is delaying. So it seems counterproductive to disable interrupts with taskENTER_CRITICAL. If you don't want other tasks to run during the delays then call a non-blocking delay function rather than vTaskDelay (). WebApr 13, 2024 · This is exactly what critical sections were designed for. We also discussed a few times that there are more fine granularity mechanisms to accomplish mutual exclusion - for example, if the exclusion is only against one single thread of execution, then a mutex (if the other thread is a task) or a “surgical” diasable of a particular interrupt (if the other …
