Which of the following is a common cause of deadlocks in FreeRTOS applications?
ANot enabling the FreeRTOS scheduler
BUsing too much heap memory for dynamic allocation
CIncorrect task priority assignment causing starvation
DTwo tasks waiting indefinitely for each other's resource
Step-by-Step Solution
Solution:

  1. Step 1: Understand deadlock concept in RTOS

    Deadlock happens when two or more tasks wait forever for resources held by each other.

  2. Step 2: Identify the scenario causing deadlock

    Two tasks waiting indefinitely for each other's resource is the classic deadlock cause.

  3. Final Answer:

    Two tasks waiting indefinitely for each other's resource -> Option D

  4. Quick Check:

    Deadlock = Mutual waiting [OK]
Quick Trick: Deadlock means tasks wait forever for each other's resource [OK]
Common Mistakes:
  • Confusing deadlock with priority inversion
  • Thinking heap size causes deadlock
  • Assuming scheduler not started causes deadlock
