Hallo i use the ATSAME70Q21 and want to use FREERTOS (8.2.3). In my example projekt i have 2 Tasks with a binary semaphore. The first task “task monitor” should notify the second task “task\_led”. I have bebugged my code:

Program sequence while debugging:

1. xSemaphoreGive() was called in task monitor() and went over.
2. xSemaphoreTake() was called in task\_led() and went over.
3. xSemaphoreTake() was called in task\_led() and stoped there.
4. xSemaphoreGive() was called in task monitor() went over and called after that the HardFault\_Handler().

Can you help me? Tank you for your support. Why was the HardFault\_Handler() called? Where ist the problem?

Best regards  
Andre

What does delay\_ms() do? What happens if you replace delay\_ms() with  
vTaskDelay()?
