FreeRTOS - Task Priorities

You have tasks with priorities 2, 3, and 3. How does FreeRTOS handle scheduling if all are ready?

ARuns tasks randomly regardless of priority

BRuns priority 2 task first, then priority 3 tasks

CRuns only one priority 3 task forever

DRuns priority 3 tasks in round-robin, then priority 2

Step-by-Step Solution

Solution:

Step 1: Identify highest priority tasks
Priority 3 is higher than 2, so those tasks run first.
Step 2: Understand round-robin for equal priorities
Tasks with same priority (3) share CPU time round-robin.
Final Answer:
Runs priority 3 tasks in round-robin, then priority 2 -> Option D
Quick Check:
Higher priority runs first; equal priority shares CPU [OK]

Quick Trick: Equal priority tasks share CPU before lower priority runs [OK]
