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.

WebCalls to taskENTER_CRITICAL or taskEXIT_CRITICAL each provide a spinlock object as an argument. The spinlock is associated with a shared resource requiring access protection. When entering a critical section in ESP-IDF FreeRTOS, the calling core will disable interrupts similar to the vanilla FreeRTOS implementation, and will then take the spinlock and enter … WebJul 12, 2024 · Jul 13, 2024 at 14:17. The FreeRTOS website says: "The taskENTER_CRITICAL () and taskEXIT_CRITICAL () macros provide a basic critical section implementation that works by simply disabling interrupts, either globally, or up to a specific interrupt priority level." So, in my humble opinion, the taskENTER_CRITICAL () not only "lock all task ...
Webissues contain lock and unlock hooks. The lock hook is called at entry of the critical section, and the unlock hook is called at the exit of the critical section. The thread-safe solution implements the required lock-related functions.

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 ().
