FreeRTOS - Task Creation and Management

What happens if two FreeRTOS tasks have the same priority and are both ready to run?

AThe scheduler picks one randomly and runs it forever

BThe scheduler runs them in a round-robin fashion

CThe task created first always runs first

DBoth tasks run simultaneously on separate cores

Step-by-Step Solution

Solution:

Step 1: Recall FreeRTOS scheduling for equal priority tasks
FreeRTOS uses time slicing (round-robin) to share CPU between equal priority tasks.
Step 2: Understand round-robin behavior
Each task runs for a time slice, then the scheduler switches to the next task of same priority.
Final Answer:
The scheduler runs them in a round-robin fashion -> Option B
Quick Check:
Equal priority tasks = round-robin scheduling [OK]

Quick Trick: Equal priority tasks share CPU time round-robin [OK]
