FreeRTOS - RTOS Fundamentals
How can you ensure that a FreeRTOS task does not starve lower priority tasks in a system with many high-priority tasks?
ADisable the scheduler and run tasks manually
BAssign all tasks the same priority
CEnable time slicing and use priority inheritance mechanisms
DUse only one task to avoid conflicts
Step-by-Step Solution
Solution:

  1. Step 1: Understand task starvation causes

    High-priority tasks can prevent lower priority tasks from running.

  2. Step 2: Apply FreeRTOS features to prevent starvation

    Time slicing allows equal priority tasks to share CPU; priority inheritance helps with resource locking.

  3. Final Answer:

    Enable time slicing and use priority inheritance mechanisms -> Option C

  4. Quick Check:

    Time slicing + priority inheritance prevent starvation [OK]
Quick Trick: Use time slicing and priority inheritance to avoid starvation [OK]
Common Mistakes:
  • Disabling scheduler breaks multitasking
  • Assigning same priority ignores task needs
